The saddest blood type. The rarest blood group in the world

Designated by the absence or content of special substances (antigens) of type A and B in it: I - 0 (antigens are absent), II - A (type A antigen is present), III - B (type B antigen is present in the blood), IV - AB (contains both types of these substances).

Blood is also classified by the presence or absence of the Rh factor in it. The Rh factor is an antigen found on the surface of red blood cells. The rarest is determined by both indicators. According to statistics, this status is the fourth with a negative Rh factor. It has less than one percent of the world's population (mostly).

It is allowed to transfuse blood only of the same group and Rh in the patient and the donor. If absolutely necessary, it is allowed to transfuse other groups with the first blood group that has the same Rh factor.

How did the fourth blood type appear

According to scientists, in ancient times, almost all people had one blood group - the first, and therefore it is most common on most continents. Thanks to mutations, the second and third blood groups arose. Such mutations arose due to the restructuring of the primitive organism, which learned to eat, in addition to meat, fish, berries, leaves, and vegetables. According to scientists, the third blood group appeared on the territory of South Asian countries, whose inhabitants ate products obtained from animals (milk, cottage cheese, cheese, thermally processed meat, and so on).

The rarest fourth group appeared no more than 10 centuries ago, its origin is still unknown. However, there are suggestions that it arose as a result of mixing races. Since such marriages are a phenomenon, there are very few people with the fourth blood type. There is also an opinion that this type of blood appeared due to a significant increase over the past five hundred years in the human diet of foods that have undergone heat treatment, as well as synthetic and semi-synthetic foods.

According to one version, the fourth blood group was formed as a result of the defeat of the human body by viral infections.

People with the fourth have a unique ability to adapt to nutritional conditions and the environment, and their body has a high resistance to disease. Such people have a sensitive digestive system and a very tolerant immune system.

More than a hundred years ago, the main human blood types 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.

Formation of group membership of the main biological environment organism, 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, group affiliation blood 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 type of blood, because on the surface of their red shaped elements no antibodies. 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.

Carriers of the third () and fourth have excellent health, but more careful, insinuating, have a calm, gentle nature. 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 injury, serious somatic diseases. Negative qualities blood types for the third and fourth groups are reduced to increased likelihood occurrence 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, people with a variety of meat food, with the second, on the contrary, - vegetable. 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 group blood - this 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.

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 Rh positive blood, and only 15% do not have a specific protein on the surface of red cells - the Rh factor. 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 digestive system. Because of hyperacidity gastric juice they may develop gastritis, peptic ulcer, colitis. They are more likely than others to get the flu and SARS, they have a tendency to form stones in the urinary system, poor clotting blood. With a negative Rh, skin pathologies can be observed.

These people are not very resistant to stress. Their weakness – thyroid(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, bile and urolithiasis, osteoporosis, diabetes. It is recommended to monitor the weight and keep it normal, quit smoking and active image life.

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 especially susceptible to urinary infectious diseases. 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, eliminate fatty foods.

IV (AB)

The owners of this blood are resistant to SARS, influenza, bronchitis, pneumonia. They don't have skin problems, they can brag healthy teeth, rarely seen renal pathologies. 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 the worst blood, and on the development of pathologies or, conversely, on good health affects much more factors. 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 that the Rh factor is negative. From this, many conclude that the most 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 complete ban there 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 important indicator which passes to children by inheritance. It is located in the components of the blood, various bodies, 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 Rh negative, if the husband has a positive one, they 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 should also be emphasized that people with Rh positive, it can be of several types or one. That is, you can see the combination 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.

On this moment V laboratory research almost three dozen combinations stand out. 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 allowed for a safe transfusion, but in the past, the procedure often ended. lethal outcome due to non-acceptance of the patient's donor material by the body.

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 a meal 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 the best places for living and food.
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 is the 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 are different biological features, the presence of a negative Rh factor or positive.

National and racial affiliation determines the presence a certain kind 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 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 recipient is incompatible, this will lead to serious problems and even to death.

If mixed 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 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?

Eat universal donors are the people in 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 above rules practical medicine do not apply. 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, in this case, it is necessary to carry out this procedure. It is also urgently done if a person in state of shock after surgical treatment.

It is not uncommon for a transfusion to be given to patients diagnosed with anemia, serious blood disorders, 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 level 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. Drugs are added to the donor's normal blood, which increase healing 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 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 treatment severe complications diseases 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 invaded 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 vitality will occur. important processes in organism. 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 illnesses for 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 type.

Usually for donation blood of any group is paid the same amount, but since the fourth blood type, especially with a negative Rhesus, is the rarest, then on the black market or in any private organizations they will not pay clearly more than 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 public institutions and hospitals 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. Just eat 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 group?

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?

The world leader in rarity is 4 negative group blood. 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 conditions. environment. 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 susceptible to allergies. 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 kinds blood types vary greatly in prevalence around 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 rare group blood, then for the delivery of tests he can be rewarded more than the rest. Increased remuneration aims to compensate for the deficit necessary group blood. 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 how expensive it is, I can’t say, I don’t know how it is evaluated donated blood. 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 may be infected people Donating blood was not seen 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 from the fourth negative blood a transfusion is necessary, it will be extremely difficult to find a second person with identical blood.

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 blood types:

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 her positive traits in principle and 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.

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. High blood pressure their frequent companion.

But they tend to suffer various diseases digestive system.

For example, they also have poor blood clotting. Can get sick with a variety of ailments skin. 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 thyroid gland. Thus, there are problems with the production of hormones. They are also subject 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 the syndrome chronic fatigue. A heart attack avoids people with 3 blood types. Tendency to colon cancer. In general, they tend to acute experience stressful situations.

People with the fourth blood group are more likely 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 group Blood III, then the chance that a child will be born with the fourth blood type IV is 50%.

3. And the rarest option is when both parents are happy owners of the fourth blood group, 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 ideal group blood. 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 group blood - 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. Rolling occurs with incompatible groups blood, this is how the blood type 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 loss is a dangerous phenomenon, fraught with sharp deterioration well-being, death. Thanks to advances in medicine, doctors are able to compensate for blood loss by transfusing donor biomaterial. It is necessary to carry out transfusions, taking into account the type of blood of the donor and recipient, otherwise the patient's body will reject someone else's biomaterial. There are at least 33 such varieties, of which 8 are considered the main ones.

Blood type and Rh factor

For successful transfusion you need to know exactly her blood type and Rh factor. If they are not known, a special analysis must be done. By their own biochemical features blood is conditionally divided into four groups - I, II, III, IV. There is another designation: 0, A, B, AB.

The discovery of blood types is one of the most significant developments in medicine in the last hundred years. Prior to their discovery, transfusions were considered a dangerous, risky business - only sometimes they were successful, in other cases the operations ended in the death of the patient. During the transfusion procedure, another important parameter is also important - the Rh factor. In 85% of people, red blood cells contain a special protein - an antigen. If it is present, the Rh factor is positive, and if not, the Rh factor is negative.

85% of Europeans, 99% of Asians, 93% of Africans are Rh positive, the rest of the people of these races are negative. The discovery of the Rh factor took place in 1940. Doctors were able to determine its presence after long studies of the biomaterial of rhesus monkeys, hence the name of the antigen protein - “rhesus”. This discovery made it possible to drastically reduce the number of immunological conflicts observed during gestation. If the mother has the antigen, but the fetus does not, a conflict occurs that provokes hemolytic disease.

What blood type is considered rare: 1st or 4th?

According to statistics, the most common group is the first: its carriers are 40.7% of the world's population. There are slightly fewer people with type B biomaterial - 31.8%, these are mainly residents of European countries. People with the third type are 21.9% of the world's population. The fourth blood type is considered the rarest - it is only 5.6% of people. According to the available data, the first group, unlike the fourth, is not considered rare.

Due to the fact that not only the group of the biomaterial, but also the Rh factor is important for transfusion, it must also be taken into account. So, people with a negative Rh factor of the biomaterial of the first variety in the world are 4.3%, the second - 3.5%, the third - 1.4%, the fourth - only 0.4%.

What you need to know about the fourth blood type

According to research data, the AB variety appeared relatively recently - only about 1000 years ago as a result of mixing blood A and B. People with the fourth type are distinguished by strong immune system. But there is evidence that they are 25% more likely to suffer from diseases of the heart and blood vessels than people with blood A. People with the second, third group suffer from cardiovascular diseases 5 and 11% less often than those with the fourth.

According to therapists and psychologists, the carriers of the AB biomaterial are kind, selfless people who are able to listen, show sympathy and provide assistance. They are able to feel the depth of feelings - from great love to hatred. Many of them are real creators, they are people of art, sensitive to music, appreciating literature, painting, sculpture. There is an opinion that among the representatives of creative bohemia there are many people with this kind of blood.

Their creative nature is in constant search for new emotions, they fall in love easily, and have an increased sexual temperament. But they have their drawbacks: they are poorly adapted to real life, are absent-minded, offended by trifles. Often they cannot cope with their emotions, their feelings take up over reason and sober calculation.

Features of transfusion

The transfusion procedure should be carried out taking into account the Rh factor - both the donor and the recipient. If these laws are ignored, the recipient's immune system will reject the donor's biomaterial, which causes kidney failure, agglutination of erythrocytes, shock and death of the patient.

In order for the donor biomaterial to be ideally combined with the recipient's immune system, it must be of the same type and Rh factor. However, in some cases, blood of different types and Rh factors is well combined, as can be seen from the erythrocyte compatibility table (horizontally - the recipient, vertically - the donor).

In Japan, you're more likely to be asked about your blood type than your zodiac sign. Accounting and blood type tests here they call it "ketsu-eki-gata" and take it very seriously. After all, each group has certain characteristics of character and health.

The blood group is a set of specific substances, individual for each person, called group antigens. It does not change throughout a person's life and can be inherited. The most common is the first blood type, it is possessed by about 40% of all inhabitants of the planet. But many consider it the worst.

Features of blood groups

The first blood group 0 (I) according to the AB0 system means that human erythrocytes are completely devoid of antigens. It is worth noting that the first positive can be used as universal blood for the transfusion procedure. If a person is injected with blood with a negative Rh, then as a result, red cells, that is, erythrocytes, will stick together, with a subsequent deterioration in the person's condition. But despite this, you can often hear that people with the 1st blood group are more susceptible to various diseases.

And this is connected with the research of Japanese scientists: people with this group have worse blood clotting. But in many cases it is rather a merit. Because of this, they are much less likely to have thrombosis and all the diseases associated with them: thromboembolism, heart attacks, stroke ... The fact is that almost every blood type is associated with some problems and advantages, and it is wrong to say that one is worse than the other . Here are the diseases associated with each blood type.

How diseases are related to blood group

1. I group

   Due to reduced clotting, thrombosis, vascular disease, myocardial infarction, and ischemic stroke are less common. Also, people with this blood type are less prone to pancreatic cancer, but more prone to developing stomach and duodenal ulcers than others. They also have a lower ability to conceive, especially after 30 years. Therefore, do not delay too much with the firstborn.

2. II group

   People with this blood type are often distinguished by longevity and good immunity. They are less prone to colds and infectious diseases. But the second blood type increases the risk of gastritis with low acidity, the appearance of stones in bile ducts And chronic cholecystitis. Also, people with this blood type are more likely to acute leukemia and stomach cancer. Japanese scientists say that people with the second blood group are more important than the rest of quality rest to maintain health.
