The rarest blood group. What is the rarest blood type in humans?
To date, many features of the body’s activity have not yet been fully studied by scientists. Some blood characteristics also remain a mystery. IN modern medicine It is customary to distinguish between blood different people by group, as well as by Rh factor. In any laboratory, employees can determine these human characteristics, which are then used by doctors when it is necessary to carry out various medical procedures (mainly blood transfusions). Today we are talking about what is the most rare blood and the Rh factor of human blood.
What is Rh factor and blood group?
Today, a system known as AB0 is used to evaluate blood group; it was proposed by the scientist Landsteiner, who lived at the beginning of the last century. Wherein:
0 – considered the first blood group;
A – second blood group;
B – third blood group;
AB – fourth blood group.
In addition to blood group, doctors distinguish another difference - the Rh factor. Such a particle is essentially an antigen present on the surface of red blood cells in approximately 85% of people and, accordingly, readers of Popular About Health. Accordingly, people who have this antigen are called Rh-positive, and those who do not have it are called Rh-negative.
The rarest human blood type in the world
The fourth group with a negative Rh factor is considered the rarest in humans. The fourth positive blood group is found a little more often: even more often than the third negative, second negative and first negative.
Scientists claim that the fourth blood group as a whole is quite mysterious and, most likely, the youngest - it appeared in people not so long ago as a result of the fusion of two other blood types A and B.
There is a theory that people with this blood type are quite flexible immune system. Also, some scientists are confident that the emergence of the fourth blood group is a consequence of the practice of mixed marriages. And this group is characterized by high biological complexity. Sometimes its features are similar to the second blood group, sometimes to the third. But much more often, this blood type is a kind of combination of both groups A and B.
Some scientists are confident that the fourth blood group in the world arose about a thousand years ago, due to the mixing of the Mongoloid race and Indo-Europeans.
Today, carriers of the fourth positive group blood can be considered 5% of the world's population, and the fourth negative is observed only in 0.4%.
The rarest Rh factor in the world in blood
So, as we already understood, the most rare is the absence of the Rh factor, in other words, a negative Rh factor. This feature is typical for only 15% of the planet's population. And to date, not a single scientist can explain why a small number of people do not have antigen on their red blood cells.
In most cases, the rare negative Rh factor does not affect the quality of life at all. But sometimes such a criterion is very important, for example, during blood transfusion and donation, as well as during pregnancy. After all, if the mother is Rh-negative and the fetus is Rh-positive, a so-called Rh conflict arises, which requires the use of a number of medications to maintain the pregnancy.
Bombay blood
Bombay blood or bombay phenomenon- this is an amazing name new group blood, which, according to scientists, was discovered in the middle of the last century in India.
Bombay blood does not have antigens A or B (which are characteristic of the second - A, third - B, or fourth blood group - AB). It would seem that in such a situation, it is identical to the first blood group - Oh, but this is not so. Bombay blood does not contain the H antigen, which is present in the first blood group. Research shows that this phenomenon occurs in approximately 0.01% of Indian residents. Bombay blood does not cause any problems to its owner, except that only the same blood can be used for blood transfusion. At the same time, Bombay blood is surprisingly suitable for donation - it is compatible with all four blood groups.
Thus, we can conclude that the rarest blood group is still the fourth negative. Bombay blood is not yet recognized as the rarest, since it is a phenomenon (only in a given area and in too few people) and cannot be used to obtain statistical data.
Additional Information
Some experts are confident that a particular person’s blood type has a direct impact: on his health, taste preferences and even character. So, according to such scientists, owners of the fourth negative blood group are different strong immunity, but at the same time suffer from weak digestive system. They quite often encounter viral infections, which are able to penetrate the body through the gastrointestinal tract.
People with fourth negative group blood differ strong character, but at the same time they are touchy and vulnerable. Quite often such individuals seem strange. At school and university they are attracted to various Mind games and all kinds of activities. They are also distinguished by their curiosity.
Scientists also suggest that people with blood type IV are especially prone to developing anemia. They need to stick dietary nutrition to prevent recruitment excess weight.
In fact, the rare Rhesus and the rarest blood groups do not in any way affect a person’s life and do not distinguish him from the rest, with the exception of situations where the need for blood transfusion arises, and also with the exception of pregnancy.
Blood differs by group and Rh factor, and each group has its own Rh factor - negative or positive. Depending on the composition of the blood, today there are four groups: the first (0), the second (A), the third (B) and the fourth (AB). Let's figure out which one is the best rare group blood in the world.
Blood type: percentage for all people on the planet
If you pay attention to the statistical data, you will see that forty percent of people on Earth have the first blood group. The second blood group is characteristic of thirty-two percent of all people on the planet. Twenty-two percent of people have the third blood group. The fourth blood group is found in only six percent of the total population of the planet. Based on this, we can make an absolutely reliable conclusion - the rarest blood group is the fourth.
Taking into account the Rh factor, the rarest group is the fourth negative. This blood type is determined in 0.4 percent of people worldwide. In general, on average, 85 percent of people are Rh positive by blood, while only 15 percent are Rh negative. It is much more common to find people with fourth positive blood, which is considered quite young. And the fourth negative is distributed very unevenly across the territory of our planet. For example, only 0.05 percent of people with such blood are Chinese.
Fourth negative
So, judging by the statistical information presented, the fourth blood group with a negative Rh factor can truly rightfully be classified as the rarest. This blood differs in its biochemical properties, so sometimes it is simply very difficult to find donors with such blood when they are so badly needed. Scientists note that today blood groups are not subject to change at all. Although with the development of primitive man quite dramatic changes took place in this regard. Why on this moment no new blood groups arise, researchers do not know. But they suggest that the emergence of a fifth blood type is not excluded.
Bombay blood is a real phenomenon!
A person born into the world receives a blood type depending on the hereditary factor. For example, if the parents have the first blood group, then the child will also be born with the first blood group, if the parents are the owners of the second and third groups, then the child can have any of the four blood groups. However, there are always exceptions to the rules, and children may be born with an unintended hereditary factor blood group. In this case, the blood is called “Bombay”. It lacks antigens A and B. When analyzed, it is easily confused with blood of the first group, but the difference is that it does not contain antigen H.
Scientists discovered this peculiar phenomenon in 1952, when Bombay blood was discovered in a resident of Bombay. In India, 0.01 percent of people have such blood flowing in their veins, but throughout the world, only 0.0001 percent of the population can be found with such blood.
And it is hardly possible to judge which one is the most the best group blood, but if the owner of Bombay blood urgently needs a transfusion, then finding a donor will not be easy. Although Bombay blood can be transfused to people with different group blood, and no blood at all negative consequences for a person it will not be.
Fourth negative: character traits of people
By their nature, people with this blood type are distinguished by their nobility, kind heart, selflessness, and calmness. As a rule, they are altruists and prone to creative professions. They should also be especially concerned about their health - heavy physical activity is contraindicated for such people, since their body is not very adapted to “overload.” Instead of serious sports, they should prefer yoga classes, which will be truly beneficial to health and quite feasible for the body.
Otherwise, a person with this blood type is no different from other people with more common groups. In any case, the character can turn out to be the same even if absolutely different groups blood. However, the main problem for people with fourth negative is finding a donor if necessary.
The defining component of blood is the Rh factor or antigen. It is located on the surface of red blood cells (erythrocytes). More than 85 percent of the population have this Rh factor and are classified as Rh positive.
Those people who do not have it are considered Rh negative. The present and future of a person depends on his blood type. Each group has its own type of immunity, which to a certain extent determines a person’s life resource.
How to find out your blood type
So, there are four blood groups in total, each of which differs in certain biochemical characteristics. This fact has been established by science a long time ago - around the beginning of the twentieth century.
Throughout the world, these groups are designated by the following symbols: I(0), II(A), III(B), IV(AB). The first is the most common throughout the world, since approximately 45 percent of the inhabitants of our planet have it.
The blood of the second group belongs to the majority of European residents, and almost 35 percent of the population have it. The third group is not very numerous, since it is found in only 13 percent of the world's population.
Well, the fourth blood group is the rarest, because only 7 percent of the planet’s population are its carriers. And if owners of the first blood group with a negative Rh factor are quite common, then Rh-negative owners of the fourth blood group are very rare.
Donate blood for donation
It is worth saying that positive blood A negative one can overflow, but the opposite should not be done under any circumstances.
The first blood group can be transfused to any group, but it is important to remember that under no circumstances should blood of another group be transfused to it - only the first.
Blood of the second group is suitable for the second and fourth, but for her only the first or second.
The third blood group can be transfused to the third or fourth, but the first or third is suitable for it.
The fourth blood group, the rarest, is allowed to be transfused only to people who have a similar blood type, but for the fourth, any blood type is suitable.
Most common blood type
The most common first blood group
This group is the oldest, which appeared a long time ago. Those with the first blood group usually have a predisposition to allergies, arthritis, decreased thyroid function, and also a tendency to blood clotting disorders. In addition, such people often suffer from stomach ulcers and other diseases directly related to the gastrointestinal tract.
As for personal characteristics, those with the first blood group are, as a rule, leaders in life. They are quite successful in sports and are often workaholics. This is very purposeful people who always try to achieve their goals.
The rarest blood type
The rarest blood type is fourth negative. The fourth positive is much more common. The fourth group is generally a mystery, because it appeared as a result of the merger of two completely different types- A and B.
This is a young group, and people who have it have a flexible immune system. This group is unique in that it appeared not due to the influence of the external environment, but as a result of mixed marriages. It is worth saying that this group is the most biologically complex.
Antigens sometimes make it similar to the second, and sometimes even to the third. Sometimes it also happens that this rare group is something of a combination of both of these groups.
It is believed that the fourth blood group appeared later than all the others - about a thousand years ago as a result of the mixing of Mongoloids and Indo-Europeans. There is also another version of the so-called “bohemian” blood group, which says that after a person was able to simply provide shelter and food for himself, he was “drawn to the beautiful” and he had a desire to express himself in creativity.
Indeed, representatives of the fourth blood group are considered the most creative individuals. The lives of such people are dominated by fantasies, emotions, love of beauty and intuition. They have a rich mental organization, a subtle perception of reality and impeccable taste.
The positive qualities of such people are kindness, compassion, selflessness and altruism. Such a person will always listen, reassure and sympathize. But at the same time, the sensitivity of such people can be considered their disadvantage.
Due to the fact that those with the fourth blood group take everything too seriously, they sometimes get carried away. These people often go to extremes. They, as a rule, act under the influence of feelings that are so intense that the mind is simply unable to curb them.
By the way, there are many fanatics among such people. But even if it doesn’t come to the point of fanaticism, the owners of the fourth group most often look like people slightly “not of this world.” They are impractical, absent-minded, often completely unsuited to solving everyday problems, and they are also very touchy about all this.
The craving for beauty in those with the fourth blood group can also manifest itself in different ways: from the creation of works of art among the most developed representatives, right up to psychological dependence from romance, sex and pleasure among the more primitive, which sometimes leads them to a vicious lifestyle.
It cannot be said that those with the 4th blood group are quite multifaceted and spiritual. They often rush from one extreme to another, and can be both harsh and indecisive. Such people can often be seen in lists of the most talented and remarkable personalities.
In general, despite many advantages, owners of the fourth blood group would still benefit from some qualities that are characteristic of people with the first blood group - discipline and fortitude, for example. But even if the named character traits were not inherited by a person from birth, he may well develop them throughout his life, because habit, as they say, is a second character.
Behind long history existence, humanity was forced to adapt to the changing conditions of the earthly world. The man himself and his biochemical properties. IN modern world It is known that people's blood does not have the same Rh factor and group affiliation. The rarest of them is described in the article.
What is blood in general or rare blood - what is it? Blood is a special mobile tissue in a liquid state that connects the entire internal fluids, that is, it is plasma, and it contains cells, red blood cells. Each blood has its characteristics, including immunity.
Human bodies have different working resources, plasma has its own needs. The blood indicator is the Rh factor, that is, a special protein on the surface of red blood cells called erythrocytes. Rhesus is divided into positive with a sign (Rh(+)) and negative with a sign (Rh(–)).
Various processes can occur in the body; our most precious biological fluid reacts to each of them. The reaction is reflected in the results of human blood tests. Based on research and scientific data, tables are compiled so that people can compare their ideas with accurate information.
The tables contain symbols indicating the groups: I(0), II(A), III(B), IV(AB). Among the indicators there are rare ones, there is data on prevalence, each line provides certain knowledge.
The most common group in the world is the first; almost half of the inhabitants of planet Earth have such blood. Most Europeans are carriers of the second group, the third group is small, found in only 13% of earthlings.
The rarest in the world is the fourth. There are quite a lot of people with the first blood group with a negative Rh factor, for some reason the fourth Rh negative blood group is considered rare. The first two groups are recognized as the most common, the third is less common, but the rarest is the fourth negative. Of all the varieties, it has become the most rare species, the most mysterious. A small number of earthly inhabitants were lucky enough to become owners of the fourth group. So this is the rarest group blood in people.
A conditional rating was formed based on the demand for all known types of blood transfusions. Each type differs from the others in its resistance or susceptibility to different diseases.
About the rarest blood group
In the twentieth century, many scientific discoveries occurred, among them the conditional classification of blood into groups. This was a good advance in medicine, especially with in case of emergency saving people. Bleeding is a very life-threatening situation. The discovery made it possible to find donors and prevent unnecessary blood mixing, thereby saving many, many human lives. As it turned out later, in nature there are different subtypes of blood, explained by the presence of Rh factors. It turned out that among all the groups there is the rarest group IV. The types differ in the content of agglutinogen proteins on the surface of red blood cells.
People need to know where they belong. To the question, what is the rarest blood group, there is a simple answer - IV (–), phenomenal. And the first negative is inherent in 15% of Europeans, about 7% of Africans and is almost absent among Indians. Science continues its research on these topics.
Why is group 4 singled out?
About two millennia ago, a new amazing sign of blood was formed. Then it turned out that this is the rarest group. The exclusivity lies in combining into one whole the complete opposites of blood type - A and B. But it is the most needed at all blood transfusion stations. Scientists have noticed that the owners of this phenomenon are endowed with a flexible system of protecting the body from diseases (immune).
Modern biology considers this group complex, which did not appear under the influence environment, but due to the mixing of people of different religious denominations or belonging to different racial communities. In addition, IV is inherited only in half of the cases when both parents have such blood. If one parent has type AB, then there is only a 25% chance that children will be born with this group. The antigens present affect its properties in different ways, sometimes similarities with the second appear, sometimes signs of the third are noticeable. And sometimes this rare group demonstrates a peculiar combination of both groups.
Regarding features, indicators characteristic features, health status there are some conclusions. For example, people with a rare group are less adapted to long-term physical activity. It is advisable to replace burdensome sports activities with light, acceptable yoga. Psychological characteristics These people are manifested in nobility, sincerity, composure and calmness. They show more of their spiritual organization in creativity.
The carriers of the rare fourth group are not deprived by nature; they live and develop like all other inhabitants of the planet. The only concern may be the issue of donation.
Most common
There is a group in nature that is much more common than the fourth. This is the first one, it is called universal. The rest are placed somehow in order of priority. About half the population has it. However, such statistics are relative and approximate. The fact is that every nationality has specific features according to groups and Rh factor, it is believed that this phenomenon is associated with heredity.
The first is not only the most common, but also the most, one might say, universal. If during transfusion it is necessary to carefully approach the combination of blood groups, then the first one is suitable for all patients, regardless of their group affiliation. This versatility is explained by the absence of antigens; this is confirmed by the marking number 0.
World distribution statistics
There are about 3 dozen varieties of blood groups known in the world. In our country, the classifier of the Czech scientist Jan Jansky is used, according to which liquid tissue divided into 4 groups. The classification is based on the presence of antigens (substances foreign to the body) on the surface of red cells -.
The separation occurs according to the ABO system:
I (0) – absence of antigens;
II (A) – antigen A is present;
III (B) – antigen B is present;
IV (AB) – antigens A and B are present.
Statistics show the prevalence of people by blood type:
| Blood type | Found in the population |
| (I) 0 + | 40% |
| (I) 0 | 7% |
| (II) A+ | 33% |
| (II) A – | 6% |
| (III) B + | 8% |
| (III) B – | 2% |
| (IV) AB + | 3% |
| (IV) AB – | 1% |
This shows that the percentage of people with blood group 4 is the smallest. In emergency cases, group affiliation marks in a passport or military ID can help.
The rarest Blood group in the world is IV. The child inherits 50% of the group from his parents. Regarding Rh, Rh is individual compatibility. It is very important for the conception and development of a child that these indicators coincide in both parents. Often miscarriages during pregnancy occur for precisely these reasons.
Blood group affiliation usually does not change in people throughout their lives, including after a transfusion.
Transplantation and manipulation features
Often people find themselves in extreme situations when acute blood loss represents real threat life. The main indication is blood transfusion, and this is a very serious, responsible manipulation. This complex action has its own characteristics and characteristics. This requires strict adherence to the rules approved for such cases and highly qualified specialists. The rules for conducting a kind of operation without incisions on the patient’s skin are strict and provide for these manipulations in inpatient conditions, to instantly respond to all kinds of reactions or complications. Medical workers If possible, try to find a life-saving method without such a procedure.
The reasons for performing a transplant from a donor to a patient may be:
- heavy bleeding;
- state of shock;
- prolonged bleeding, including during complex surgical operations;
- low content in severe anemia;
- deviations in the processes of blood formation.
During a transfusion, the patient's health is directly dependent on the coincidence of group affiliation and the Rh factor. Rh mismatch leads to fatal outcome. Universal groups are I and IV.
In the human community, the phenomenon of voluntary donation of blood or its components is widely practiced. For donation, people all over the world donate their biological tissues. Donor material is used for scientific, research, educational purposes, and is used to make medicines. It is also needed for emergency transfusion. The effect is achieved only when full compatibility blood of the donor and the recipient of care. This must be a group match, according to Rhesus, and also individual compatibility.
Thus, human blood represents a mysterious natural phenomenon with which the very existence of man and his characteristic features are connected. This living organism exhibits wonderful properties, which have not yet been fully studied. Scientists continue to find answers, but there is a lot ahead interesting work requiring attention and full dedication.
Blood loss is a dangerous phenomenon, fraught sharp deterioration well-being, the death of a person. Thanks to advances in medicine, doctors are able to compensate for blood loss by transfusion of donor biomaterial. Transfusions must be carried out taking into account the type of blood of the donor and recipient, otherwise the patient’s body will reject the foreign biomaterial. There are at least 33 such varieties, of which 8 are considered basic.
Blood type and Rh factor
For a successful transfusion, you need to know exactly the blood type and Rh factor. If they are not known, a special analysis must be done. According to its biochemical characteristics, blood is conventionally divided into four groups - I, II, III, IV. There is also another designation: 0, A, B, AB.
The discovery of blood types is one of the most significant events in medicine over the last hundred years. Before their discovery, transfusions were considered a dangerous, risky business - only sometimes it was 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 it is not, the Rh factor is negative.
85% of Europeans, 99% of Asians, 93% of Africans have a positive Rh factor, while the rest of the people of the listed races have a negative Rh factor. 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 macaques, hence the name of the antigen protein - “Rhesus”. This discovery made it possible to sharply reduce the number of immunological conflicts observed during pregnancy. If the mother has an antigen, but the fetus does not, a conflict occurs that provokes hemolytic disease.
Which blood group 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 make up 21.9% of the world's population. The rarest blood type is considered to be the fourth - this is only 5.6% of people. According to available data, the first group, unlike the fourth, is not considered rare.
Due to the fact that not only the group of biomaterial is important for transfusion, but also the Rh factor, it must also be taken into account. Thus, in the world there are 4.3% of people with a negative Rh factor of biomaterial of the first variety, 3.5% of the second, 1.4% of the third, and only 0.4% of the fourth.
What you need to know about the fourth blood group
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 have a strong immune system. But there is information that they are 25% more likely to suffer from heart and vascular diseases than people with blood A. People with the second and third groups suffer from cardiovascular diseases 5 and 11% less often than those with the fourth.
According to therapists and psychologists, carriers of AB biomaterial are kind, selfless people who are able to listen, show sympathy and provide help. They are able to feel the full 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, and sculpture. There is an opinion that among representatives of the creative bohemia there are many people with this type of blood.
Their creative nature is in constant search of new emotions, they easily fall in love, and have a high sexual temperament. But they have their drawbacks: they are poorly adapted to real life, are absent-minded, take offense over trifles. Often they cannot cope with their emotions; their feelings take precedence 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 neglected, the recipient’s immune system will reject the donor’s biomaterial, which causes renal failure, adhesion of red blood cells, 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 combines well, as can be seen from the red blood cell compatibility table (horizontal - recipient, vertical - donor).
