Which blood group has the strongest immune system? Dependence of diseases on blood type. Which group is the least common?

The predisposition to the development of oncological diseases of certain organs is affected by a person's blood type. The information received from researchers of this dependence warns us to pay more attention to those organs that are most at risk.

Take care of yourself, eat right and!

Any tumor sends a signal about itself, which can be detected in the blood serum. A preliminary study showed 95 percent accuracy in detecting breast cancer at stages 0 and 1 and lung cancer at stages 1 and 2. At the same time, the symptoms of the disease usually begin to appear only in the second stage. The test works by mixing enzymes from patients' blood with a dye and some amino acids.

Not everyone knows about the relationship between blood type and susceptibility to certain diseases. Research began in the twenties of the last century and continues to this day. Recently it became known that scientists have learned to determine the presence of oncology by blood. The new diagnostic method was tested on three thousand people.

Among the subjects were those who suffered from cancer and those who were completely healthy. The effectiveness of the new method, to the surprise of scientists, is amazing. The result confirms other scientific data. After all, it is in the blood that antibodies are produced that can resist the invasion of viruses, microbes and toxins into the body. And since the blood of different people is different, it is logical to assume that the ability of this blood to suppress the development of certain diseases is also different.

What risks await representatives of different blood groups?

The first blood group. You should be careful about your stomach, because they have a 35% higher risk of developing an ulcer than other people. In addition, the first group is susceptible to lung diseases such as tuberculosis and asthma. But such people suffer from heart disease much less often.

Second blood group. The risk of cancer, you should beware of stomach cancer and leukemia. In addition, such people often develop cholecystitis and stones appear in the gallbladder and kidneys.

Third blood group. The risk of tumors, heart attacks and other heart diseases, women are more likely to have various diseases of the urogenital area.

Fourth blood type. The risk of facing stomach cancer, as well as susceptibility to disease. With age, such people have an increased risk of mental illness and memory loss. But lung diseases often bypass these people.

The presence of risks does not mean that a person will necessarily get sick according to the blood type. There is a risk, but with a certain diet and lifestyle, this risk is reduced significantly, you should not panic, but you should still take care of the prevention of diseases of your blood type.

I continue to collect and accumulate materials on the topic of the division of mankind into several species that are quite different from each other. When I consider that there are enough materials, I will make a review, but for now I have posted it as a reference.

About blood types

In 1907, the Czech scientist J. Jansky established that a person has four blood groups. He divided blood groups according to their ability to stick together red blood cells of other blood types. If the blood type is not defined, then when blood is transfused from one person (donor) to another (recipient), as a result of the interaction between the erythrocytes and the blood plasma of the donor and the recipient, erythrocytes can stick together (agglutination) and their subsequent destruction (hemolysis). The reason for the gluing of erythrocytes is the presence in the blood of special substances associated with blood proteins: in plasma - agglutinins (denoted by the Greek letters ALPHA and BETTA) and in erythrocytes - agglutinogens (denoted by Latin letters A and B). Bonding of erythrocytes occurs with homogeneous agglutinins (A + ALPHA or B + BETTA), which is a factor, the so-called blood incompatibility group.

Agglutinogens and agglutinins in the blood are in different ratios. Thus, agglutinogens are not contained in the first blood group - it is designated O (I), and agglutinins ALPHA and BETTA are present in the plasma.

Blood group II contains agglutinogen A and agglutinin BETTA; this group is designated A (II).

Group III contains agglutinogen B and agglutinin ALPHA.

Group IV contains - agglutinogens A and B, but does not contain agglutinins. Designated AB.

It has been proven that in the human body there are many genetically determined, inherited blood factors combined into antigen systems. The strongest antigens are antigens of blood groups of the ABO system.

The problem of the relationship between blood group antigens and various organ diseases has long attracted the attention of researchers. Already in the 20s of the XX century. studies were conducted to establish a relationship between blood groups and diseases of internal organs and body systems.

Each type of blood is its own defense system against infections, viruses, bacteria, toxic compounds. The main guardians of our body - antigens - are attached to red blood cells like antennae. Detecting an invasion of their territory, say, by a virus, antigens produce antibodies that rush to the enemy and stick to him. As a result, the virus loses its mobility and becomes very sticky. What happens next is what scientists call agglutination: viruses stick together in groups, as a result of which they are expelled from the body.

Human defense mechanisms have evolved over thousands of years. His habitat, lifestyle, nutrition system changed - in response to this, the entire immune system, blood composition were transformed, new mutations of antigens were created. According to the most powerful of them, the blood type is determined.

If you mix two different blood groups on a glass plate, the rejection reaction will be so strong that it can be observed with the naked eye: cells of the same group will bind with foreign blood antigens.

But few people know that the same binding reaction (agglutination) occurs when blood is mixed with certain foods: antigens contained in food will agglutinate blood cells of one group, but interact perfectly with another. This is because many food antigens are similar to the A and B antigens in human blood - such substances are called lectins. The nature of their perception or rejection by our blood is dictated by the genetic heritage transmitted to us with the blood group. The emergence of various blood groups occurred as a result of natural selection, in the course of the evolutionary development of man. The most ancient is the first blood type, which was among the Neanderthals, Cro-Magnons: This is followed by the second and third blood types, which, respectively, were possessed by people of later eras - settled tribes and the first emigrants to Europe and Asia. The fourth, the youngest blood type, is the result of a mixture of all blood types.

Blood groups and diseases of the gastrointestinal tract

People with the first blood group (it is the most common among Europeans) have a predisposition to gastric and duodenal ulcers. The presence of the first blood type increases the risk of developing gastric and duodenal ulcers by 35% compared with individuals with other blood types. There is an opinion that the first blood type causes the development of membrane receptors on the gastric mucosa that are sensitive to Helicobacter (bacteria that causes peptic ulcer and chronic gastritis, in some cases is one of the causes of stomach lymphoma). For this reason, in people with this blood group, the resistance of the gastric mucosa to the action of digestive enzymes is reduced.

The second blood group is a predisposition to gastritis with low acidity. People with this blood type are also more vulnerable to the formation of stones in the bile ducts, they often develop chronic cholecystitis (inflammation of the gallbladder).

The third blood type is a predisposition to colon tumors.

The fourth blood group - there is no data on predisposition to diseases of the stomach and intestines in the literature.

Blood types and dental caries

Caries - the destruction of hard tissues of the tooth - can occur due to many, currently insufficiently studied, causes. The development of caries is often complicated by pulpitis, manifested by pain. For the first time, the relationship between the occurrence of dental caries and the presence of one or another blood group was mentioned in 1930. It was found that caries occurs most often in people with the second and third blood groups. These people are carriers of genes that predispose to the development of this disease.

Caries is rarely found in people with the first blood group.

Resistant to caries are also people with AB fourth blood group, especially women. They have a minimal risk of caries and a more favorable course of this disease.

In persons with the second blood group, the development of the pathological process in the hard tissues of the tooth is acute (rapidly progressing). Inflammation very quickly spreads to the pulp (soft part of the tooth) and periodontal tissues, in a short time a large number of teeth are affected by caries.

In people with the third blood group, despite the high risk of developing caries, the course of the disease is more favorable (it develops slowly and can be treated).

Blood groups and purulent-inflammatory diseases of the soft tissues of the face

It has been established that the course of purulent-inflammatory diseases of the soft tissues of the face and neck (furuncles, phlegmon, abscesses) is more severe in people with the second and fourth blood groups. Sometimes the disease is complicated by sepsis (purulent lesion of the whole organism).

In persons with the first and third blood groups, purulent processes proceed more benignly.

Blood groups and diseases of the cardiovascular system

Diseases of the heart and blood vessels, such as angina ("angina pectoris"), myocardial infarction, atherosclerosis, are the main cause of death in young and middle-aged people.

People with the first blood group have the highest risk of developing hypertension.

The second blood group is a predisposition to the development of coronary disease, acquired mitral heart disease, as well as congenital heart disease such as Fallo's tetralogy (when all four heart valves are affected).

Many heart diseases, including a defect, arise as a result of rheumatism. A tendency to rheumatism is observed in persons with the second blood group.

People with the second and fourth blood groups have a high risk of high cholesterol levels, more likely to develop atherosclerosis and heart disease, obesity. In addition, people with the second and fourth blood groups have diseases associated with increased blood coagulation: thrombosis, thrombophlebitis, obliterating endarteritis of the lower extremities.

Blood groups and tumors

The second blood group causes a predisposition to the development of stomach cancer, acute leukemia ("leukemia", "blood cancer").

The third group is a predisposition to colon cancer.

In people with "the first blood type, colon cancer occurs, but much less often and the prognosis of the disease is more favorable.

Blood groups and diseases of the blood system

The predisposition of people with the first blood group to hemophilia A has been established (a disease in which there is no blood coagulation factor; it is complicated by prolonged bleeding with minor injuries, death from blood loss can occur without medical care); thrombocytopenic purpura (a disease in which the number of platelets, cells involved in the blood clotting process, is reduced). The second blood group is a predisposition to acute leukemia.

Blood types and thyroid disorders

Thyroid diseases are more common in people with the second blood type.

Blood groups and mental illnesses, as well as conditions close to them

Studies conducted by Australian psychiatrists have shown that among patients with schizophrenia, the smallest number of patients with the first blood group. While among people with the third and fourth blood groups there is a large number of patients suffering from neurosis and psychosis

It is also assumed that the genes of the blood group are so close to the genes of the mental state that this can later serve as a marker of disease processes.

Blood groups and diseases of the kidneys and genitourinary system

The most predisposed to the development of nephrolithiasis are people with the first and second blood groups. The first blood group is distinguished by nephrologists as the highest risk factor for the development of this disease.

Women with the third blood group are most susceptible to frequent urinary tract infections (especially if the infection is caused by Escherichia coli, since there is a similarity between the structure of the antigens of Escherichia coli and the third blood group). The most resistant to the development of kidney disease are people with the fourth blood group.

Blood groups and skin diseases

Egyptian scientists have found that people with the first blood group, especially those with negative Rh, are more likely to suffer from skin diseases. Less commonly, skin diseases occur in people with the fourth blood group.

Blood groups and lung diseases

Individuals with blood type O (I), especially those with a negative Rh, are most predisposed to the development of diseases of the bronchi and lungs. Among them, pulmonary tuberculosis, chronic allergic bronchitis, allergic conditions accompanied by pathology of the bronchial system, and bronchial asthma are in the lead. The least susceptible to lung diseases are people with the fourth blood group.

Let's take the plague epidemic as an example. People with the first blood type are most susceptible to plague (at one time this led to the death of a population of people with this blood type).

People with II, III, IV blood groups acquired immunity as a result of the disease, which, in turn, led to the death of the microorganism and the preservation of the human population.

Smallpox mainly affects people with the second and fourth blood groups. People with type I blood are more likely to get influenza A.

Features of nutrition in I-IV blood groups

The four blood groups are a reflection of the characteristics of human development.

Those with group I bear the features of our hunter ancestors.

II blood group - farmers.

People with the III blood group in their lifestyle are wanderers who are in constant motion.

People with IV are organizers and administrators.

This also determines the peculiarities of the digestive system in people with different blood groups.

First blood group

The main products are meat and fish. They can be eaten every day. Herbal products are also helpful. The exceptions are all types of cabbage, which affects the functioning of the thyroid gland, and corn, which affects the production of insulin. It is also worth limiting the consumption of fruits with a high content of acid - oranges and tangerines.

Dairy products and eggs should be strictly limited. Cereals and products from them slow down the metabolic processes in the body of the owners of this blood type, resulting in excess weight - therefore, their consumption must be minimized, or even better eliminated altogether.

Second blood type

The most useful food is vegetable, and preferably raw. Meat is recommended to be excluded completely. If this is not possible, then it is better if it is lean poultry meat. The gastrointestinal tract in people with the second blood type simply cannot cope with the digestion of meat products. Dairy products and beans, as well as in people with the first blood group, slow down the metabolism - their amount in the diet should be limited.

Third blood type

Give up corn, buckwheat, wheat - they slow down the metabolism. If you want to lose weight or never gain weight, cut them out completely. Meat, dairy products, eggs are useful. However, it should be noted that chicken meat is less useful than, for example, lamb.

Fish, unlike seafood (they are simply harmful to people with the third blood type), has a beneficial effect on the entire digestive system. Of vegetable oils, olive oil is preferable. Oils made from nuts and seeds, however, like nuts and seeds themselves, are harmful. From vegetables, tomatoes are harmful. Try to eliminate them from your diet.

Fourth blood type

Meat is not the most useful product for people with this blood type, but it is necessary. It is recommended to eat meat in very small portions. Red meat is not suitable, as well as chicken. Seafood / fish, snails and crayfish are very useful (flounder is an exception). Consumption of beans, corn, buckwheat and wheat should be limited - they slow down the metabolism. Dairy products do not pose any danger, on the contrary, they improve the production of insulin. Oil - olive oil is better, rice - instead of pasta, vegetables are useful for everything. Bananas and oranges are best avoided.

Each of them can be Rh-positive or Rh-negative, which means that there are 8 types of blood. The question may arise as to which one is the best. It is possible to consider any blood better than others only if it is always possible to quickly find a donor for its owner with significant blood loss. Thus, we can conclude that the best group is the most common.

According to statistics, about half of all the inhabitants of the planet have the blood of the first group, about 40% are carriers of the second, about 8% of the population have the third group, and only 2% of people have the fourth. The vast majority (85%) are owners of Rh-positive blood, and only 15% do not have a specific protein, the Rh factor, on the surface of red cells. From this we can conclude that the best group is I positive, and this means that such blood can always be found, in contrast to the fourth negative.

The best one is universal?

The blood of group 0 (first) is called universal, since it is believed that it can be transfused to everyone. The fact is that she does not have A and B antigens on erythrocytes, which means that the recipient's body will not begin to produce antibodies against them. Thus, the first group can be considered the best, since its carrier can save any person in case of blood loss.

On the other hand, AB can be transfused only to owners of the same, and to no one else. At the same time, anyone with a fourth can become a donor, since there are no antibodies to antigens A and B in the AB blood plasma.

Blood type and predisposition to diseases

There is an assumption that, depending on the blood, people are prone to certain diseases, but this has no scientific justification.

It is believed that these people are mentally stable. As for diseases, they have a predisposition to arterial hypertension and diseases of the digestive system. Due to the increased acidity of the gastric juice, they may develop gastritis, peptic ulcer, colitis. They are more likely than others to suffer from influenza and SARS, they have a tendency to form stones in the urinary system, poor blood clotting. With a negative Rh, skin pathologies can be observed.

These people are not very resistant to stress. Their weak point is the thyroid gland (insufficient production of hormones). They are prone to dental diseases. In addition, they are advised to be more attentive to the heart: diseases such as coronary artery disease, hypertension, heart attack are not excluded. They are prone to gastritis with secretory insufficiency, cholelithiasis and urolithiasis, osteoporosis, and diabetes mellitus. It is recommended to monitor the weight and keep it normal, quit smoking and lead an active lifestyle.

Blood type can indicate a predisposition to certain diseases

III(B)

Among the carriers of this group, neurasthenics and people prone to psychosis are most often found. There is a high risk of developing hypertension, pancreatitis, rheumatism, Parkinson's disease. Women are particularly susceptible to urinary tract infections. It is believed that people with the 3rd group are less likely than others to have a heart attack. They are advised to give up bad habits, move more, exclude fatty foods.

IV (AB)

The owners of this blood are resistant to SARS, influenza, bronchitis, pneumonia. They do not have skin problems, they can boast of healthy teeth, kidney pathologies are rarely observed. There is a tendency to hypertension, atherosclerosis, obesity, hepatitis, anemia. These people quickly coagulate blood, hence thrombosis, thrombophlebitis.

Conclusion

In fact, there is no better or worse blood, and many more factors influence the development of pathologies or, conversely, good health. Even if the tendency to disease depends on it, then, as a rule, if there are strengths, there are also weaknesses. Thus, if we consider that there is a best group, then this is the most common.

What blood type is considered the best?

Today, in the world, human blood is classified according to the AB0 system, as well as the Rh factor. According to this classification, a person can be one of four groups:

• the first is denoted by the number 0;
• the second letter A;
• the third letter B;
• the fourth is a combination of their AB.

Moreover, each can have a positive or negative Rh factor. Accordingly, human blood can be divided into four groups or eight types. In this regard, the question often arises, which is the best.

Most often, the question of what kind of blood is the best arises when it comes to donation. That is, it is assumed that it is best to have a type that occurs most often. That is, the most common blood should be the best, but is it really so?

Prevalence and versatility

The most common worldwide, according to research, the first. About half of the inhabitants of the world have this type. The second one is in second place. Approximately forty percent of people have it. The fourth one is the least numerous. Only two percent of people have it, and the remaining eight are in the third. Thus, the most common option is the first or second group.

However, it is necessary to take into account not only the group, but also the Rh factor. Most people - about 85 percent, it is positive. By and large, it means that the Rh factor is present in the blood. The remaining 15 percent do not have it, that is, we are talking about the fact that the Rh factor is negative. From this, many conclude that the best blood is the first positive, since it is the easiest to find, and the worst is the fourth negative.

The first group can also be attributed to the universal. It is believed that in donation it can be used for any person, since it lacks the A and B antigens. Accordingly, the recipient's body will not perceive the blood as something alien. Therefore, the first group is considered one of the best for donation. Since everyone can transfuse it, it means that almost anyone can be saved with it.

But, despite the fact that this group is very popular, its owners can only be transfused with the same first group. At the same time, the fourth group, which is not the most popular, is able to accept any type, due to the absence of antibodies to antigens A and B in the plasma.

Transfusion Basics

It must be understood that in the modern medical world it is forbidden to transfuse, unless absolutely necessary, blood that differs from the recipient group. Under a complete ban is a blood transfusion with an excellent Rh factor. Ideally, you need to transfuse the same type that the recipient has.

The Rh factor in donation is an important indicator that passes to children by inheritance. It is located in the components of the blood, various organs, amniotic fluid. When a person with a negative Rh factor is transfused with a positive type, the body begins to produce specific antibodies. We can say that the body is protected from something alien.

Often, a different Rh factor of parents becomes a problem for bearing a child. Therefore, pregnant women with a negative Rh, in the presence of a positive husband, are examined more carefully.

You can be sure that if not the first, then the second transfusion can be fatal for a person with a different Rhesus from the transfused blood. It is also worth emphasizing that in people with a positive Rh, it can be of several types or one. That is, you can see a combination of different types, which is also important to consider when transfusing. Therefore, it is important to determine what kind of blood the recipient has and what kind of blood the person who donated the material for donation has.

In most cases, modern physicians distinguish six antigens in the Rh factors of the two systems. In humans, the presence of both systems or only one can be distinguished.

At the moment, almost three dozen combinations are distinguished in laboratory studies. Before performing a transfusion, the presence of Rh is established, as well as an analysis for Rh compatibility. Returning to the question of the best type, doctors note that this by and large does not exist. The fact is that rare phenotypes do not speak of their special demand, because with the rarity of the phenotype, we can say that it will be useful to a smaller number of people.

Transfusion specialists are sure that it is wrong to consider rare groups as bad. Every day the need of clinics for certain components and blood of a particular group changes. Therefore, a situation often occurs in which the rarest on this day is the most common. Why do doctors call for donation of all healthy people, regardless of their group and Rh affiliation.

What blood type is the rarest

A blood transfusion often saves a person's life. But in order for the procedure to really help, and not harm, it is necessary to match the group and Rh factor of the blood of the recipient and the donor.

There are four types of this biological fluid. Among them there is the rarest blood type in humans, and the most common.

How group and rhesus are determined

At the beginning of the 20th century, scientists developed a conditional classification into groups from 1 to 4, each of which is divided into two subspecies - negative or positive - depending on the Rh factor.

The difference lies in the content on the surface of red blood cells of specific proteins - agglutinogens A and B, whose presence affects the belonging of the plasma of a particular person to a certain group.

If the D antigen is present, then the Rh is positive (Rh+), if it is absent, it is negative (Rh-). This separation made it possible to perform a safe transfusion, but earlier the procedure often ended in death due to the patient's body not accepting the donor material.

Group Determining Factors

In Russia, the designation is valid:

• the first is 0 (zero), or I, the antigen is absent;
• the second - A, or II, there is only antigen A;
• the third - B, or II, there is only antigen B;
• the fourth - AB, or IV, in the presence of both antigens A and B.

The blood type is laid at the genetic level, by transferring antigens A, B to offspring.

Principle of classification

Over the centuries, the type of plasma has been formed as a result of natural selection, when people had to survive in various climatic conditions. According to scientists, initially there was only 1 group, which became the ancestor of the rest.

1. 0 (or I) - the most common, was present in all primitive people, when the ancestors ate what nature gave and managed to get - insects, wild plants, parts of animal food left after the meal of large predators. Having learned to hunt and having destroyed most of the animals, people began to move from Africa to Asia, Europe, in search of better places to live and live.
2. A (or II) arose as a result of forced migrations of peoples, the emergence of a need to change the way of existence, the need to learn to adapt to live in a society of their own kind. People were able to tame wild animals, took up farming and stopped eating raw meat. Currently, most of its owners live in Japan and Western Europe.
3. B (or III) was formed in the process of merging populations, adaptation to changing climatic conditions. It first appeared among the Mongoloid race, who gradually moved to Europe, entering into mixed marriages with the Indo-Europeans. Most often, its carriers are found in Eastern Europe.
4. AB (or IV) is the youngest, which arose about 1000 years ago not as a result of climate change and living conditions, but due to the mixing of Mongoloid (type 3 carriers) and Indo-European (type 1 carriers) races. It turned out as a result of the merger of two different types - A and B.

The blood group is inherited, however, not always the descendants coincide with the parent. It remains unchanged throughout life, even a transfusion or bone marrow transplant is not able to change its appearance.

Rare and common blood

Most often in any country there are people with types 1 and 2, they account for 80–85% of the population, the rest have 3 or 4 groups. Species differ from one another in biological characteristics, the presence of a negative Rh factor or a positive one.

Nationality and race determines the presence of a certain type of plasma.

Among Europeans, residents of Russia, 2 positive prevails, in the East - the third, among representatives of the Negroid race, the first dominates. But in the world IV is considered the rarest, in isolated cases there is a fourth negative.

Most of the world's inhabitants are Rh positive (almost 85% of the European population), and 15% are Rh negative. As a percentage of residents of Asian countries, Rh "Rh +" occurs in 99 cases out of 100, in 1% it is negative, in Africans - 93% and 7%, respectively.

The rarest blood

Many people are interested in whether or not they have a rare group. You can find out from the table below by comparing your own data with statistical data:

What type of blood can we talk about as the most demanded in donation?

Blood transfusion is a common and effective method of treatment. If there is little of this biological fluid in the body, or it has acquired pathological properties, death may occur. Therefore, donors are needed to save lives and fight serious diseases. Thanks to blood transfusion, doctors successfully save the lives of thousands of people. Hemotransfusion has been used since the middle of the century before last.

Blood transfusion is a procedure for which doctors must carefully prepare so as not to harm the patient. If the blood of the donor and the recipient is incompatible, this will lead to serious problems and even death.

If you mix different groups, an agglutination reaction occurs when red blood cells stick together and no longer perform their functions, or antibodies are released in the recipient's body and destroy foreign cells.

The AB0 system (by group) is used to classify blood. According to her, there are only four groups: the first is 0, the second is denoted by the Latin letter A, the third is B and the fourth, it is marked with two letters - AB.

According to the Rh factor, there are only two types: positive and negative. Based on this, 8 combinations of blood types are distinguished. The question often arises, which blood type is the most popular in donation?

Immediately it is worth clarifying that there is a universal blood that suits everyone, it is safe to transfuse it to any person. It is common, therefore it is not considered the most popular in donation. And there is blood, the carriers of which are very few on Earth, it is considered rare.

Blood group and Rh factor, let's take a closer look

The combination of antigens in erythrocytes and blood plasma determines the group. It never changes in humans, since the set of proteins in cells is always the same.

Scientists have made several classifications of blood, they appeared because there are many antigens on the cells that form antigen systems. In practice, only one AB0 classification is used.

There are three types of antigens on human red blood cells: H - inactive, A, B and AB - active. Groups are encrypted with these Latin letters. Only instead of the letter H they write the number 0 for convenience, which means that there are no antigens. Near the letter designation write I, II, III or IV. By these Latin numbers, people can understand what kind of blood type is encrypted.

In addition, there is a special protein in the blood, it is called agglutinin. It is denoted by two Greek letters - beta and alpha. It is he who leads to the destruction of red blood cells if they carry a mismatched set of proteins. This happens when a different blood type than the recipient enters the body.

Based on this, it is clear that there is a specific combination of antigens and agglutinins, according to which the blood group is determined. The second group contains antigen A and agglutinin beta. In the third, on the contrary, B and alpha. In the first group, there are both agglutinins, since there are no antigens. In the plasma of the fourth group, there are A and B antigens, so there are no agglutinins.

Human blood has a constant Rh factor, it is written as Rh, + or -, depending on whether it is positive or negative. The Rh factor is also determined by the presence of antigens on the surface of red blood cells. There are 6 proteins that encode the Rh factor. If the cells have protein D, or C + E, then the blood is Rh +. If these antigens are not present - Rh-.

This indicator also determines whether it is safe to do a transfusion or not. But if the situation is critical, it is permissible to mix positive and negative Rh.

Which group is the most common

What is the most demanded blood in medicine for donation, rare or common? let's figure it out.

Based on the statistics, we note that the first group is more common than others. Approximately half of the entire population of the planet is its carrier. C II (A) - 40% of the population. Only 9% of people with the third group, and 4% - with the fourth. The vast majority (85%) have Rh+. Only 15% are Rh-negative.

We conclude that people with I (0) Rh + blood are the most, so it is the most common. IV (AB) Rh- is considered the rarest. Sometimes it is very necessary, therefore it is collected and stored in special banks, where it can be purchased. How much does the 4th blood group cost, you can find out at the bank or from the doctor.

Universal means the best?

There are universal donors - these are people with the first group. This is because there are no antigen proteins on their erythrocytes, so the recipient's body does not perceive it as foreign, and does not produce antibodies that destroy the infused cells. Due to its versatility, the first group is considered the best.

And blood groups with A and B proteins can only be injected into people with the same set. There is also a universal recipient - a person with the fourth group. His body will accept any set of antigens.

However, the rules listed above do not apply in practical medicine. Today it is forbidden to mix different groups and Rh factors. Therefore, both the donor and the recipient must have the same set of proteins. An exception is made only in emergency cases.

And yet, which group is the most in demand?

Based on the above information, two conclusions arise:

1. The most demanded blood type is I (0) Rh +, since the vast majority of people with this group.
2. IV (AB) Rh-positive and negative are much smaller, therefore it is more difficult to find it. All because there are very few people in whose veins such blood flows. And if the patient has to do a transfusion, it will be difficult to find a donor.

When is a blood transfusion required?

Transfusion is done due to severe blood loss. If the patient loses about 30% of the blood within a few hours, then this procedure should be performed. It is also urgently done if a person is in a state of shock after treatment with surgical methods.

Often, transfusion is prescribed to patients who have been diagnosed with anemia, serious blood diseases, inflammatory processes in the body and purulent-septic diseases, severe and severe intoxication of the body.

The procedure is prescribed for people with such diseases:

• leukopenia - a sharp decrease in the level of leukocytes;
• hypoproteinemia - low levels of protein in the blood;
• sepsis - infection of the blood with microbes;
• ESR violation.

For transfusion, blood is mixed with all its components, drugs and blood substitutes. Medications are added to the donor's normal blood, which increase the therapeutic effect, while reducing the risk of complications after the procedure.

Often, an erythrocyte mass is injected into the patient's body. To do this, the erythrocytes are first separated from the frozen plasma. After that, a liquid with a high concentration of red cells is poured into the recipient's body. This method is used for anemia, acute blood loss, with the development of malignant tumors, after tissue and organ transplantation.

A mass of leukocytes is infused with agranulocytosis, when the level of these cells is rapidly decreasing, and the treatment of severe complications of diseases of an infectious nature. After the procedure, the level of white cells in the blood increases, which favorably affects the course of recovery.

When to use fresh frozen plasma:

• severe blood loss;
• DIC;
• hemorrhages - blood flows out through the damaged walls of blood vessels;
• overdose of coagulants;
• diseases of an infectious nature.

Patients with blood diseases are in particular need of transfusion. Some patients have to do this procedure once a week, or even more often.

Transfusions are also given to people after chemotherapy. If the tumor has affected the bone marrow, after therapy, not only malignant cells stop growing, but also healthy ones.

Often, women need a transfusion after a difficult birth, during which they lost a lot of blood. Sometimes doctors do not recommend using a man's blood for this. Women are considered safer, and for a young mother this is especially important.

Contraindications

This is a complex and risky procedure. In case of failure, a number of violations of vital processes in the body will occur. Therefore, doctors always take this issue seriously. Examine diseases and information about transfusions that have already been done to the patient.

The procedure is contraindicated in patients with malformations and other serious heart diseases. With violations of blood flow in the vessels of the brain and protein metabolism in the body, with allergies.

Often, even in the presence of contraindications and serious diseases for the treatment of which a transfusion is required, doctors perform this procedure. But at the same time, they prescribe drugs to the patient to prevent diseases that may appear after it.

Therefore, the answer to the question of which blood type is most in demand in modern donation is ambiguous. Since only the native group is transfused to the recipient, and there are more people with I (0) Rh +, and they are transfused more often, it is in demand. And there are much fewer people with IV (AB) Rh + or -, but if a person with such a group needs to have a transfusion, it is problematic to find a donor.

Which blood type is the most expensive and why?

The most expensive blood type is the first (both positive and negative Rh factor). Because it is universal and suitable for transfusion to people with all other blood types.

The majority of the population of our country has the second blood group.

Usually, the same amount is paid for donating blood of any group, but since the fourth blood type, especially with negative Rh, is the rarest, they will not pay clearly more on the black market or in any private organizations than for the rest.

The fourth is only suitable for the fourth, the first is not suitable for the fourth, it’s good to write nonsense

Officially, for any blood type in government agencies and hospitals, they pay the same. But in any private clinics or illegally, the largest amount is most likely paid for the 4th blood group with a negative Rh, since there are not very many people with such a combination, and they have more opportunities to dictate their conditions and price.

In total, there are four main most common blood types:

The popularity of the group decreases from the first to the fourth:

At the same time, the fourth positive is more common than the fourth negative.

If a donor donates blood, then the price for all types is the same, as far as I know. It's just that there is more valuable blood compared to others in terms of the possibility, if anything, to get it.

And I have the rarest blood type - the fourth negative. So if anything, it will be difficult for me to find a donor.

What is the rarest blood type in the world and why

There are many classifications that divide blood into groups. All of them are designed with different antigens and antibodies in mind - small particles that are either attached to the membrane of red blood cells or float freely in the plasma.

The first experiments on blood transfusion most often ended in the death of the patient. The thing is that then people did not have the slightest idea about blood types. To date, the most common classifications are the AB0 system and the Rh factor system.

According to the AB0 system, blood is classified as follows:

What determines the rarity of a blood type?

The rarity of blood types, like many other features of our body, depends on natural selection. The fact is that throughout the two-million-year history of mankind, people had to adapt to new conditions of existence.

The climate changed, new diseases appeared, and our blood developed with them. The oldest and most common group is the first. Scientists believe that it was she who was the original, and all the groups known today went from her.

Rare groups appeared much later, so they are not so common in the population.

Which group is the least common?

In the world, the 4th negative blood type is the leader in rarity. Despite popular belief, 4 positive is about 3 times more common. There are more people with it than the owners of blood of the 3rd negative group.

Why is group 4 the least common?

The fact is that its very appearance can be considered a peculiar phenomenon. It combines the properties of two opposite types of blood - A and B.

People with blood group 4 have a strong immune system that easily adapts to environmental conditions. By the standards of biology, this group is the most complex.

This type of blood appeared only a couple of thousand years ago. At the moment, it is the most demanded at any blood transfusion station, since there are still not so many of its carriers.

The youngest and rarest group is the fourth to the content

What is the most common blood type?

The most common blood of the first group (or zero according to the AB0 classification). The second is a little less common.

The third and fourth are considered rare. The total percentage of their carriers in the world does not exceed 13-15.

The most common types (1 and 2) arose at the dawn of mankind. Their carriers are considered the most prone to allergies of various origins, autoimmune processes and other diseases. The blood of this type has changed little over hundreds of thousands of years, therefore it is considered the least adapted to modern conditions.

The percentage of blood types also determines the Rh factor. Positive is much more common than negative. Even 1 negative group, which is the leader among negative blood types, occurs in 7% of people.

The distribution of blood into groups also depends on race. In a person of the Mongoloid race, the blood will be positive for Rh in 99% of cases, while in Europeans, positive Rh is about 85%.

Europeans are the most common carriers of group 1, Africans are 2, among Asians 3 is the most common.

Blood types: percentage prevalence

As statistics show, different types of blood vary greatly in prevalence in the world. Type 0 people are easy to find, and type AB blood is unique in its own way.

The following table will help you finally understand which of the groups are the most common, and which are much less common:

Which blood type is the most expensive and why?

Donation is valued the same regardless of your blood type. But the rarest and most deficient group is 4 with ANY Rhesus.

In total, there are four main most common blood groups:

The popularity of the group decreases from the first to the fourth:

At the same time, the fourth positive is more common than the fourth negative.

Most often, if a person is a carrier of a rare blood group, then he can be rewarded more for passing tests than others. The increased reward is aimed at compensating for the deficiency of the required blood type. You can read more about paying donors here.

The fourth with a negative Rh is the rarest, as far as I understand). As for "dear" - so it is not known how to evaluate? By the way, I was interested recently at the transfusion station in our city - is donation paid or free? And it turned out that it is free, completely).

If a donor donates blood, then its price for all types is the same, as far as I know. It's just that there is more valuable blood compared to others in terms of the possibility, if anything, to get it.

And I have the rarest blood type - the fourth negative. So if anything, it will be difficult for me to find a donor.

The rarest blood type is the fourth negative, in my opinion about 4% of the world's population have it. But I can’t say how expensive it is, I don’t know how donated blood is evaluated. When donating to a donor, if a reward is paid, then it does not depend on the blood type.

The fourth blood type is considered the most expensive - this is because it is the least common in people, there are very few of it. Also relatively expensive is the first blood type - as it suits all blood types.

The smaller the supply of something in the market, the higher the price at a certain level of demand. The fourth blood type with a negative Rh factor is the least common. Basically, especially abroad, money for donating blood is not paid. This is done so that drug addicts and others who may be infected do not perceive blood donation as income. Even now, not all viruses can be detected in a timely manner and there is still a risk of infection during blood transfusion.

What is the most popular blood type for donation?

You can answer this question in different ways. Many people who are not related to medicine have an opinion that the most universal, and therefore in demand, is the first, Rh negative group 0 (I) Rh (-). Yes, it is universal, but there is a law according to which only blood or blood components corresponding to the blood of the recipient are used in blood transfusions. Those. if a person has a second Rh positive group, then ONLY the second Rh positive can be transfused to him.

Therefore, it is difficult to say what kind of blood is in demand. There are statistics:

80% of the world's people have Rh positive blood

Blood type 0 (I) is the most common on the planet - it flows in the veins of 45% of humanity.

A (II) blood group prevails among Europeans - its carriers are approximately 35% of people.

B (III) blood type is less numerous - it can be found in only 13% of us.

AB (IV) blood type is the rarest on Earth, it is found in only 7% of people.

Based on the statistics, several conclusions can be drawn: 1) most likely, blood of the first group, Rh positive, is most often needed, because it is most often found and there should be more people who need it;

2) on the other hand, blood of the fourth group, and even Rh negative, is much more difficult to find, if only because there are extremely few people on earth with this group and Rh! If a person with a fourth negative blood needs a transfusion, then a second person with identical blood will be extremely difficult to find.

There is another point, the most demanded blood type is the one that is the least in the storage of the donor center)

Is there a better blood type

Everyone knows that in the medical environment there is a traditional typology of blood groups - AB0, as well as an indicator of the Rh factor, but which blood type is considered the best. Based on this, there are the following types of blood groups:

Rh factor

There is also a negative and a positive Rh factor. Such features are given to us by nature itself and to a greater extent biological parents influence this. And it depends on what groups the father and mother have. And many are interested in what type of blood is the best in a person. Of course, this question arises when blood is needed for donation.

Blood Rh factor table

The conclusion suggests itself that the best blood type is the most common in the population and the most accessible to physicians.

Statistics

According to the data, the most common is blood type 1. According to statistics, its owners are one second of the population of the planet Earth. And it is more common in medical practice.

But its positive qualities, in principle, are limited by its prevalence, and it is suitable for transfusion. In previous times, people did not take into account the plasma group factor, which was a mistake. Science does not know the reason for the quantitative superiority of a certain group.

On the topic of the Rh factor, it should be mentioned that only about 15 percent are Rh negative. The red cells of these people are deprived of such a protein as the Rh factor.

Approximately forty percent are owners of 2 blood groups. The third type of plasma is inherent in about 8 percent. The rarest is the 4th blood group, it has about 1.5-2 percent of the population. Let's try to determine if there is a better blood type for a person.

Features of blood groups

The blood of the first group is supposed, as mentioned above, to be the most common and it is suitable for all other types of blood. Her secret lies in the fact that her erythrocytes do not possess substances such as antigens (A) as well as (B). For this reason, the body of the person to whom it is transfused will not create antibodies against them. It can be awarded the title of the most functional. The owner of the fourth blood group can accept any type of blood.

It is also important for pregnancy to match the plasma types of the father and mother. The reason for this is the lack of antibodies to the above antigens in the blood plasma of type AB. A, also B.

But this type can only be transfused to people of the same group.

But this is only theoretical information. At the moment, donation is prohibited if the recipient and donor groups are of different types and have a different Rh factor.

Table of blood group compatibility for transfusion

Predisposition to diseases

Of course, there are opinions that diseases and certain characteristics of a person can be predicted by blood type.

For example, people with the first type of blood are the most stress-resistant and their psyche is quite well tolerated by a variety of stressful incidents. Increased pressure is their frequent companion.

But they tend to suffer from various diseases of the digestive system.

For example, they also have poor blood clotting. They can suffer from ailments associated with a variety of skin problems. But they have a high life expectancy, as the apologists of this theory believe. They may also be at risk for hemophilia.

The owners of the second (2) group are less psychologically stable. There is an assumption that they are prone to problems with the thyroid gland. Thus, there are problems with the production of hormones. They are also susceptible to dental diseases. Tendency to cancerous diseases of the stomach.

People of the third type of plasma are subject to psychological instability. They are also more likely to suffer from chronic fatigue syndrome. A heart attack avoids people with 3 blood types. Tendency to colon cancer. In general, they are prone to acute experience of stressful situations.

People with the fourth blood group are more prone to hematological diseases. But dermatological diseases bypass them, as well as those associated with the genitourinary system.

Of course, these data are not confirmed by science. But, however, these facts should be approached deliberately. And you can listen to these health tips. We hope you now know which blood type is best for human health and pregnancy for women.

The rarest blood type

When can a child with the fourth blood group IV be born? A child with the fourth blood type, or the rarest blood type, can be born in the following cases:

1. If one of the parents was a carrier of the second group II, and the other of the third III, then the chance that a child will be born with the fourth blood group IV is 25%.

2. If one of the parents is a carrier of the fourth blood group IV, and the second parent is with the second II or with the third blood group III, then the chance that a child will be born with the fourth blood group IV is 50%.

3. And the rarest option is when both parents are happy owners of the fourth blood type, which is incredibly rare.

Carriers of the fourth blood group are considered universal recipients. Surprisingly, the rarest blood type is unique and convenient in its own way - it is the ideal blood type. People with the fourth group can be transfused with the blood of any other group, from the first to the fourth. That is, if the owner of the fourth blood group needs a transfusion, he does not need to look for a donor of a rare, fourth group - any blood will do, but doctors will have to deal with the Rh factor.

But the blood of the fourth group can only be transfused to people with the fourth group, this blood will not suit people with either the first blood type, or the second, or the third blood type.

Rh factor is the rarest blood type

But everything is not so simple, the rarest blood type is divided into Rh positive and Rh negative groups. Rh negative blood type can be transfused to Rh positive, but Rh positive blood type cannot be transfused to Rh negative group.

The most common type of blood among people is Rh positive. The rarest blood type is Rh positive fourth, most often found in Turkey - in 7% of the population, followed by countries such as China, Israel, Poland and Finland - 7%, and in the world about 5% of the population can boast of the rarest blood type with a positive rhesus.

The fourth blood type with negative Rh is even rarer, in the world it is 0.40% of the population, while in China it is the least common - 0.05%. In other countries it does not exceed 1%.

And most often on our planet there are carriers of the first positive blood group - almost 37%.

Determination of blood groups according to the avo system, and if correct av0.

This is when the analyzed blood is added to special sera of four blood groups, and they look at the glass where clotting occurs. Coagulation occurs with incompatible blood groups, which is why the blood group is determined. The blood type should only be determined by a doctor. It happens that the blood type and Rh factor are determined incorrectly. It is very important to know not only your blood type, but also the Rh factor, as in an emergency it can save a life. Of course, you need to know the blood group of your children.

Blood is one of the most important tissues in the body and performs many vital functions. Today, in medicine and science, various classifications are used. The most familiar and frequently used is the Karl Landsteiner system, which distinguishes 4 groups (I, II, III, IV) and 2 Rh factors (positive and negative). There is still debate about which blood type is the best.

Theory about the blood group system

On the membrane of erythrocytes (red blood cells that carry hemoglobin) are agglutinogens (AG) (A, B), causing the formation of antibodies (AT) (α, β) in the plasma. Meeting in various combinations, AG and AT create 4 types:

• The first, or 0-I. Does not contain agglutinogens, but has both antibodies α, β.
• The second, or A - II. Contains AG A and AT β.
• Third, or B - III. In the composition - AG B and AT α.
• Fourth, or AB - IV. Retains both AG (A and B), but AT are absent.

In addition, the rh antigen can be located on the erythrocyte, which indicates a positive Rh factor, if it is not present, the Rh factor is negative.

For donation

Group I is suitable for donation, as it does not contain agglutinogens. And the presence of the same name AG and AT (A and α, B and β) leads to gluing (aggregation) of erythrocytes.

In the world, according to statistics, the first group is the most common, found in 45% of the world's population. Because of this fact, people with this group are less likely to donate blood for donation.

This is fundamentally wrong, since it is also required more often than others.

Type IV - on the contrary, a rarity (2% of the population). Due to the absence of antibodies in the plasma, this blood group is considered the best for the recipient.

For Sport

Blood type is associated with physical indicators: endurance, flexibility, reaction speed and strength. Let's take a look at these features and the sports that are most likely to be suitable for different GCs.

00

People with this type are distinguished by endurance and high coordination of movements, thanks to which they achieve success in many sports.

What to do: rhythmic and artistic gymnastics, long-distance running, walking, figure skating, synchronized swimming.

0A

People with the second GC are not suitable for martial arts, but they succeed in tactically difficult sports. Often involved in weightlifting and athletics, team sports.
What to do: athletics, curling, tennis, football, hockey, basketball, triathlon, biathlon.

0V

It was believed that this blood type is best suited for sports that require high rates of speed and coordination. Among martial arts professionals, there are many people with the third GC.

Things to do: boxing, karate, jiu-jitsu, all-around, diving, swimming.

AB

People with IV GC are distinguished by muscle strength. Power sports that do not require speed of movement are suitable.
Things to do: Windsurfing, powerlifting, weightlifting.

For good health

Many believe that the best blood type is the most universal, that is, the first. But each type has its own advantages and disadvantages, so it is impossible to say so unambiguously. There are statistics on the frequency of occurrence of diseases in people with each type of blood.

00

Persons with this type are less susceptible to cardiovascular diseases, there are no problems with the liver, red bone marrow, and spleen. The risk of acquiring diseases of the gastrointestinal tract is increased: ulcers, gastritis, inflammation of the appendix.

These pathologies occur in people with the first GC 3 times more often.

0A

In the second group, people with healthy intestines and genitourinary organs. But they are prone to caries and pathologies of the thyroid gland, have problems with hair, nails and skin.

0B

Type 0B is characterized by resistance to infectious diseases such as plague, tuberculosis, influenza, but a higher risk of developing malignant tumors.

AB

The fourth type is characterized by strong immunity, stable nervous system. But due to the presence of both agglutinogens, blood clotting is increased, which leads to blockage of blood vessels by blood clots.

For conception

In the issue of conceiving and bearing a child, the question of the Rh factor comes first. Approximately 85% of Europeans have a positive Rh factor. If a man and a woman have different Rh factors, then the health of a pregnant woman must be taken seriously. If the child inherits the Rh factor of the mother, there will be no problems. If a Rh conflict occurs, a miscarriage can occur without medical help.

Thus, the best blood type for conception will be the same for a man and a woman in terms of the Rh factor.

The dependence of a person's character on blood type

Psychologists believe that the blood type can be used to learn about a person's character.

People with I CC are active and courageous. Talented managers. The disadvantage is constant aggression.

Holders of the II Civil Code are distinguished by a quiet, complaisant character. They worry about the little things. Create and maintain a home.

People with III GC are impulsive natures.

They are easy-going, and the routine plunges them into depression.

The owners of group IV are considered balanced, reasonable people. They can quickly get out of a controversial situation by finding a compromise.

More than a hundred years ago, the main human blood groups were discovered. Among them, the proportion of the prevalence of the first group is the highest, and the fourth, on the contrary, the lowest. However, the person himself is not able to predict the group affiliation of his blood laid down by genetics. This determines his interest in understanding which blood type is the best and which is bad.

The formation of group affiliation of the main biological environment of the body, in fact, is the result of a long process of transformation of the digestive, endocrine and immune systems of a person, accompanied by a modification of the genetic composition of the population and its adaptation to various environmental conditions.

The blood type is directly determined by the parents. Inheriting a blood type is a rather complicated process. Some believe that it can pass from parents, but science has proven that this is not entirely true. Like any hereditary trait, blood grouping is inherited according to the laws of gene transfer described by classical genetic science.

There are cases where the fetus and mother occurs. This applies to various Rh factors for pregnant women. If, and the erythrocytes of the fetus contain an Rh-positive factor that he inherited from his father, the so-called during pregnancy may occur. The baby's blood antigens begin to be perceived by the mother's body as foreign and are destroyed by the antibodies generated in response to this.

Blood for donation

The most common are 1 and . Almost 80% of all inhabitants of the Earth possess them. As a rule, there is no shortage of donors of these blood groups. The third and fourth groups are less common.

You can try to determine which and which is bad, based on its compatibility. People with the first blood group are considered universal donors; no antigens are presented on the membrane of their erythrocytes. Such blood of the first group is compatible with all other groups.

Holders are defined as universal acceptors. They can be transfused with any blood type, because there are no antibodies on the surface of their red uniforms. A slightly different situation with blood transfusion for Rh blood. only with matching Rh factor.

Positive qualities of blood types

Considering that blood carries important genetic information, we can talk about certain qualities of character inherent in all its owners. The positive qualities of the blood types of the most common groups are considered to be the strength, integrity, stability and endurance of the nature of their owners. They are leaders by nature, quite confident and purposeful.

The carriers of the third () and fourth have excellent health, but are more cautious, insinuating, have a calm, gentle character. They love home peace and comfort, hardworking and economic.

Negative qualities of blood types

Negative sides can be considered. Carriers of the first and second groups are more prone to injuries, serious somatic diseases. The negative qualities of blood types for the third and fourth groups are reduced to an increased likelihood of viral diseases, diseases of the stomach and intestines.

To reduce the chance of developing these diseases by blood type, scientists recommend eating according to your blood type. So, a variety of meat foods are suitable for people with, while with the second, on the contrary, plant foods are suitable. The third group should not abuse dairy products, and the preferred diet for people with the fourth group is fish, seafood and vegetables.

With knowledge of your blood type, you can discover a lot of new things about yourself. However, it will not be possible to clearly indicate which blood type is the best for health. After all, the best blood type is the one with which a person was born.

Knowing the features and properties of each blood group and observing the simple rules of nutrition and lifestyle dictated by it, you can feel great and keep in great physical shape.
