Blood group o i rh is positive. Characteristics of the first blood group. Inheritance of AB0 blood groups

Just a century ago, people did not yet have such a detailed understanding of the composition of the bloodstream, much less how many blood groups there are, as anyone interested can now obtain. The discovery of all blood groups belongs to Nobel laureate Austrian scientist Karl Landsteiner and his colleague in the research laboratory. Blood group as a concept has been used since 1900. Let's figure out what blood groups exist and their characteristics.

Classification according to the AB0 system

What is blood type? Each individual has about 300 different antigenic elements in the plasma membrane of red blood cells. Agglutinogenic particles at the molecular level are encoded in their structure through certain forms of the same gene (allele) in the same chromosomal regions (loci).

How are blood types different? Any blood flow group is determined by specific erythrocyte antigen systems controlled by established loci. And the category of blood substance will depend on which allelic genes (indicated by letters) are located in identical chromosomal regions.

The exact number of loci and alleles currently does not yet have accurate data.

What are the blood types? About 50 types of antigens have been reliably established, but the most common types of allelic genes are A and B. Therefore, they are used to designate plasma groups. Features of the type of blood substance are determined by the combination of antigenic properties of the bloodstream, that is, inherited and transmitted gene sets with blood. Each blood group designation corresponds to the antigenic qualities of red blood cells contained in the cell membrane.

The main classification of blood groups according to the AB0 system:

The types of blood groups differ not only by category, there is also such a thing as the Rh factor. Serological diagnosis and designations of blood group and Rh factor are always made simultaneously. Because for blood transfusion, for example, it is vital important is both the group of the blood substance and its Rh factor. And if a blood group tends to have a letter expression, then Rh indicators have always been designated by mathematical symbols such as (+) and (−), which means positive or negative Rh factor.

Compatibility of blood groups and Rh factor

Rh compatibility and blood flow groups are given great importance during transfusion and planning pregnancy, in order to avoid conflicts of the erythrocyte mass. Regarding blood transfusion, especially in emergency situations, this procedure can give the victim life. This is only possible if all blood components match perfectly. At the slightest discrepancy in group or rhesus, red blood cells may stick together, which usually entails hemolytic anemia or kidney failure.

Under such circumstances, the recipient may suffer state of shock, which often ends in death.

In order to eliminate the critical consequences of blood transfusion, immediately before blood infusion, doctors conduct a biological compatibility test. To do this, the recipient is infused a small amount of whole blood or washed red blood cells and his well-being is analyzed. If there are no symptoms indicating aversion to blood mass, then blood can be infused in the full required volume.

Signs of blood fluid rejection ( blood transfusion shock) serve:

  • chills with a pronounced feeling of cold;
  • blue discoloration of the skin and mucous membranes;
  • temperature increase;
  • the appearance of seizures;
  • heaviness when breathing, shortness of breath;
  • overexcited state;
  • decreased blood pressure;
  • pain in lumbar region, in the chest and abdomen, as well as in the muscles.

The most characteristic symptoms which are possible when a sample of an inappropriate blood substance is infused. Intravascular administration of a blood substance is carried out under the constant supervision of medical personnel, who, at the first signs of shock, must begin resuscitation actions in relation to the recipient. Blood transfusion requires high professionalism, so it is carried out strictly in a hospital setting. How blood fluid levels affect compatibility is clearly shown in the table of blood groups and Rh factors.

Blood groups table:

The diagram shown in the table is hypothetical. In practice, doctors prefer classical blood transfusion - this is a complete match of the blood fluid of the donor and recipient. And only if absolutely necessary medical staff decides to transfuse acceptable blood.

Methods for determining blood categories

Diagnostics to calculate blood groups is carried out after obtaining venous or blood material from the patient. To establish the Rh factor, you will need blood from a vein, which is combined with two serums (positive and negative).

The presence of one or another Rh factor in a patient is indicated by a sample where there is no agglutination (sticking together of red blood cells).

To determine the blood mass group, the following methods are used:

  1. Express diagnostics is used in in case of emergency, the answer can be received within three minutes. It is carried out using plastic cards with dried reagents applied to the bottom. Shows group and rhesus at the same time.
  2. Double cross reaction used to clarify dubious result research. The result is assessed after mixing the patient's serum with red blood cell material. The information is available for interpretation after 5 minutes.
  3. Colcloning with this diagnostic method natural serums are replaced by artificial zoliclones (anti-A and -B).
  4. Standard bloodstream categorization is performed by combining a few drops of the patient's blood with serum samples with four instances of known antigenic phenotypes. The result is available within five minutes.

If agglutination is absent in all four samples, then this sign indicates that this is the first group. And in contrast to this, when erythrocytes stick together in all samples, this fact indicates the fourth group. With regards to the second and third categories of blood, each of them can be judged in the absence of agglutination in the biological sample of serum of the determined group.

Distinctive properties of the four blood groups

The characteristics of blood groups allow us to judge not only the state of the body, physiological characteristics and food preferences. In addition to all the above information, thanks to a person’s blood groups, it is easy to obtain psychological picture. Surprisingly, people have long noticed, and scientists have scientifically proven that categories of blood fluid can affect the personal qualities of their owners. So, let's look at the description of blood groups and their characteristics.

The first group of the human biological environment belongs to the very origins of civilization and is the most numerous. It is generally accepted that initially all inhabitants of the Earth had blood flow group 1, free from the agglutinogenic properties of erythrocytes. The most ancient ancestors survived by hunting - this circumstance left its mark on their personality traits.

Psychological type of people with the “hunting” blood category:

  • Determination.
  • Leadership skills.
  • Self-confidence.

Negative aspects of personality include traits such as fussiness, jealousy, and excessive ambition. It is quite natural that it was the strong-willed qualities of character and the powerful instinct of self-preservation that contributed to the survival of the ancestors and, thereby, the preservation of the race to this day. To feel great, representatives of the first blood type require a predominance of proteins in the diet and a balanced amount of fats and carbohydrates.

The formation of the second group of biological fluid began to occur approximately several tens of thousands of years after the first. The composition of blood began to undergo changes due to the gradual transition of many communities to plant species food grown in the process of agriculture. Active cultivation of the land for the cultivation of various cereals, fruit and berry plants led to the fact that people began to settle in communities. The way of life in society and joint employment affected both the changes in the components of the circulatory system and the personality of individuals.

Personality traits of people with “agricultural” blood type:

  • Conscientiousness and hard work.
  • Discipline, reliability, forethought.
  • Kindness, sociability and diplomacy.
  • Calm disposition and patient attitude towards others.
  • Organizational talent.
  • Quick adaptation to a new environment.
  • Perseverance in achieving goals.

Among so many valuable qualities There were also negative character traits, which we will designate as excessive caution and tension. But this does not obscure the overall favorable impression of how humanity has been affected by dietary diversity and changes in lifestyle. Special attention Owners of the second bloodstream group should pay attention to the ability to relax. As for nutrition, they prefer food with a predominance of vegetables, fruits and grains.

White meat is allowed; it is better to choose easily digestible proteins for nutrition.

The third group began to form as a result of the wave-like resettlement of residents of African areas in Europe, America, and Asia. Features of an unusual climate, other food products, the development of livestock farming and other factors caused changes in the circulatory system. For people of this blood type, in addition to meat, dairy products from livestock are also useful. As well as grains, legumes, vegetables, fruits and berries.

The third group of the bloodstream says about its owner that he:

  • An outstanding individualist.
  • Patient and balanced.
  • Flexible in partnerships.
  • Strong-willed and optimistic.
  • Slightly crazy and unpredictable.
  • Capable of original image thoughts.
  • Creative personality with a developed imagination.

Among so many useful personal qualities, only the independence of the “nomadic pastoralists” and their reluctance to obey the established foundations differ unfavorably. Although this has almost no effect on their relationships in society. Because these people, distinguished by their sociability, will easily find an approach to any person.

The characteristics of human blood have left their mark on representatives of the earth’s race from the very beginning. rare group blood substance - the fourth.

The extraordinary individuality of the owners of the rare fourth blood category:

  • Creative perception of the surrounding world.
  • A passion for everything beautiful.
  • Pronounced intuitive abilities.
  • Altruists by nature, prone to compassion.
  • Refined taste.

In general, carriers of the fourth blood type are distinguished by their balance, sensitivity and innate sense of tact. But sometimes they tend to be harsh in their statements, which can create an unfavorable impression. Fine mental organization and lack of assertiveness often force one to hesitate in making a decision. The list of permitted products is very diverse, including animal products and plant origin. It is interesting to note that many personality traits that people usually attribute to their merits turn out to be just characteristics of their blood type.

In contact with

Since time immemorial, blood has attracted the attention of observant people. Life was identified with her. However, its appropriate use, based on the discovery of blood groups and the development of methods for its preservation, became possible only a few decades ago. Blood is mobile internal environment the body and is characterized by a relative constancy of composition, while performing the most important diverse functions that ensure the normal functioning of the body.

Blood type is a trait that is inherited. It is an individual set of specific substances for each person, called group antigens. It does not change throughout a person's life. Depending on the combination of antigens, blood is divided into four groups. Blood type does not depend on race, gender, or age.

In the 19th century, when studying blood on red blood cells, substances of a protein nature were discovered; different people they were different and designated as A and B. These substances (antigens) are variants of one gene and are responsible for blood groups. After these studies, people were divided into blood groups:

  • O(I)- first blood group
  • A (II)- second blood group
  • B (III)- third blood group
  • AB (IV)- fourth blood group

Blood groups are inherited on a multiple basis. The variants of manifestation of one of the genes are equal and do not depend on each other. The pairwise combination of genes (A and B) determines one of the four blood groups. In some cases, it is possible to determine paternity based on blood type.

What blood type can a child's parents have?

Rh factor refers to one of the blood group indicators and refers to the innate properties of human blood. It is inherited and does not change throughout life.

Rh factor refers to proteins and is found in the red blood cells of humans and rhesus monkeys (hence the name). The Rh factor was discovered in the first half of the twentieth century by K. Landsteiner (laureate Nobel Prize for the discovery of blood group) and A. Wiener.

Their discovery helped to distinguish, based on the presence or absence of the Rh factor, Rh-positive organisms (~87% of people) and Rh-negative (~13% of people).

When transfused to Rh-negative persons Rh positive blood immune complications are possible, up to the development anaphylactic shock with fatal outcome.

In Rh-negative women, the first pregnancy proceeds without complications (without the development of Rh conflict), with repeat pregnancies the amount of antibodies reaches a critical level, they penetrate the placental barrier into the fetal blood and contribute to the development of Rh conflict, manifested by hemolytic disease of the newborn.

Determination of Rh antibodies in the blood is usually carried out in the 9th week of pregnancy. For warning severe complications anti-Rhesus gamma globulin is administered.

What can you find out about yourself?

"Ketsu-eki-gata"

If we in Russia are asked: “What is your zodiac sign?” - then in Japan - “What is your blood type?” According to the Japanese, blood largely determines character and individual characteristics human than distant stars. Carrying out tests and recording blood type is called “ketsu-eki-gata” here and is taken very seriously.

0 (I) "Hunter"; 40 to 50% of all people have it

Origin

The oldest and most widespread appeared 40,000 years ago. The ancestors led the lifestyle of hunters and gatherers. They took what nature gave them today and did not care about the future. Defending their interests, they were able to crush anyone, regardless of who he was - friend or enemy. The immune system is strong and resilient.

Character qualities

These people have strong character. They are determined and self-confident. Their motto is: “Fight and search, find and don’t give up.” Excessively mobile, unbalanced and excitable. They painfully endure any, even the most fair, criticism. They want others to understand them perfectly and immediately carry out their orders.

Men very skillful in love. They are most turned on by unavailable women.

Women greedy for sex, but very jealous.

Adviсe

Try to get rid of narcissism and arrogance: this can seriously interfere with achieving your goals. Stop fussing and rushing things. Remember that a person who strives to achieve his goal at any cost, who is indomitably striving for power, dooms himself to loneliness.

A (II) “Farmer”; 30 - 40% have it

Origin

Generated by the first forced migrations of the population, it appeared when the need arose to switch to eating agricultural products and accordingly change the way of life. Appeared between 25,000 and 15,000 BC. Each individual was required to be able to get along, get along, and cooperate with others within a densely populated community.

Character qualities

They are very sociable and easily adapt to any environment, so events such as changing their place of residence or work are not stressful for them. But sometimes they show stubbornness and an inability to relax. Very vulnerable, hard to bear insults and grief.

Men are characterized by shyness. Romantics at heart, they express their love with their eyes. They love to feel maternal care, and therefore often choose women older than themselves.

Women Shy too. They make excellent wives - loving and devoted.

Adviсe

Don't strive for leadership positions. But try to find like-minded people so that they support your interests. Don't relieve stress with alcohol, otherwise you will become addicted. And don't eat a lot of fatty foods, especially at night.

In (III) Nomad; 10 - 20% have it

Origin

Appeared as a result of the merging of populations and adaptation to new climatic conditions more than 10,000 years ago. It represents nature's desire to establish a balance between enhanced mental activity and demands of the immune system.

Character qualities

They are open and optimistic. Comfort does not appeal to them, and everything familiar and ordinary brings boredom. They are drawn to adventure, and therefore they will never miss an opportunity to change something in their lives. Ascetics by nature. They prefer not to depend on anyone. They do not tolerate unfair treatment: if the boss yells, they will immediately leave work.

Men- true Don Juans: they know how to beautifully look after women and seduce.

Women very extravagant. They can quickly win a man’s heart, but they are afraid to marry them, not believing that they are capable of a reverent attitude towards the family hearth. And completely in vain! Over time, they become good housewives and faithful wives.

Adviсe

Think about it: maybe individualism is your weakness? If there are no people close to you in spirit around you, then this is the result of your independence. The reputation of a “womanizer” or “whore” only masks the fear of love. The wives of such people have to get used to cheating, because in all other respects they are good family men.

AB (IV) "Riddle"; only 5% of people have it

Origin

It appeared unexpectedly about a thousand years ago, not as a result of adaptation to changing living conditions, like other blood groups, but as a result of the mixing of Indo-Europeans and Mongoloids.

Character qualities

People of this type love to boast that Jesus Christ had type AB blood. The proof, they say, is the analysis of blood found on the Shroud of Turin. Whether this is true has not yet been proven. But, in any case, people with the fourth blood group are quite rare. They are distinguished by a soft and meek disposition. Always ready to listen and understand others. They can be called spiritual natures and multifaceted personalities.

Men attracted by their intelligence and originality. Very sexy. But their desire to make love day and night does not mean that they are filled with deep feelings.

Women They also have sexual attractiveness, but they are very demanding in choosing men. And it won’t be easy for her chosen one, because she requires a lot of attention.

Adviсe

You have a significant drawback: you are very indecisive. Perhaps this is partly the reason for your lack of conflict: you are afraid of ruining your relationship with someone. But you are in constant internal conflict with yourself, and your self-esteem suffers greatly from this.

What is the AB0 system

In 1891, Australian scientist Karl Landsteiner conducted research on erythrocytes - red blood cells. And I discovered an interesting pattern: in some people they differ in sets of antigens - substances that cause an immune reaction and the formation of antibodies. The scientist designated the found antigens with the letters A and B. Some have only antigens A, others only B. And still others have neither A nor B. Thus, the research of Karl Landsteiner divided all of humanity into three parts, in accordance with the properties of the blood : Group I (aka 0) - there are neither A nor B antigens; Group II - there is A; III - with antigen B.

In 1902, researcher Decastello described the fourth group (antigens A and B are found on red blood cells). The discovery of two scientists was called the AB0 system. Blood transfusion is based on it.

Red blood cell compatibility

The blood flowing through our vessels has certain immunogenetic characteristics. It is by these that the antigens present in this biological fluid are determined. Many of them are similar. Some are even identical. Based on their similarities, it is customary to group them into. Today, it is customary to distinguish four of them. But there is information that another one will appear soon. And this will be blood of group zero. But before talking about these developments, it is worth noting the already existing 0(I).

Total information

Many people wonder: what is blood type zero? The first one, actually. It is designated in the system as follows: “AB 0:0”. Although this option is more common - 0(I).

Scientific research confirms that this group blood is the most common in the world. For a long time there were no other options on the planet. This group is the simplest in its structure, which is confirmed by its chemical analysis.

A child with 0(I) can be born to parents, each of whom has 0(I). Or if at least one of them has the first group, and the second has the third or second.

Reflection on preferences

Surprisingly, a person’s first (zero) blood group affects his life (meaning the everyday level). People with, as a rule, love meat, do not have digestive problems, and have excellent immune system and react positively to physical exercise and loads. But it’s difficult for them to adapt to new living conditions.

They also say that blood type affects character. Scientists assure: this is due to the fact that our biological fluid was transformed under the influence of changes in the environment and the “legacy” of our ancestors. So, people with 0(I) are very emotional, sociable, purposeful and active. Besides good health, they still have well-developed willpower. However, negative qualities often appear, which include hot temper, aggressiveness and even cruelty to some extent.

With a plus sign

Now it is worth considering such a moment as the Rh factor. And we will start with the “plus”. Positive zero blood group - what is its characteristic biological fluid? Especially chemical structure We won’t go into detail; it’s better to note its reflection on human physiology.

People with 0(I) Rh+ live longer than others, this is confirmed by research from the University of Göttingent, which proved that 60% of people over 75 years of age have a positive first group. They are resistant to neuroses and rheumatoid diseases, but are susceptible to ulcers and skin diseases. And also people from the first positive group usually look younger than their age.

With a minus sign

Now it’s worth talking about the owners of 0(I) Rh-. If we talk about ailments, these people are susceptible to allergies, obesity and hypertension. They are also more often exposed to diseases such as pneumonia, tuberculosis, influenza, and ARVI. They have weak immunity. These people are also very strong-willed, but they can be narcissistic, overly jealous and intolerant of criticism. What about the pros? Holders of 0(I) Rh- have a well-developed sense of self-preservation. Perhaps, among the positive things about the named owners, the “negative” is all.

That's all, by the way. general information about the biological "category" known as 0(I). But is there a zero blood type under the usual designation “0”? Let's talk about this in a little more detail.

Donation problem

Unfortunately, cases often occur that require But not all groups and Rh factors are compatible. For a person with the first negative, for example, only identical blood is suitable. And the owner of the fourth negative can be given any - he is

The point is that incompatibility different groups leads to problems associated with donation - not everyone who needs it can be saved. And scientists believe that if you create universal blood zero group, then the issue will be resolved.

But this is a very serious task. It is necessary to remove agglutinogens from it, which glue red blood cells together. Various attempts have been made to achieve this - they have also been used coffee beans, driving down agglutinogen B, and various bacteria. On this moment Scientists are working on creating a device that could create type O blood from any other.

Research

Naturally, doctors would not have such ideas without compelling reasons. But they exist. Type 0 blood is not just a project, but a theory supported by research. However, little is known about them. But there is information that certain observations have been carried out over the course of 20 years.

Doctors regularly interviewed patients who, by their consent, had been transfused with “nullified” blood. They were about 27,500 men (from 40 to 75 years old) and more than twice as more women(from 30 to 55). Analyzes were performed using a log stepwise test. We took into account age, attitude towards nicotine and alcohol, body weight index, history hereditary diseases and especially the presence of one of the relatives coronary disease heart disease, diabetes or high cholesterol.

Is there a zero blood group now, is blood transfusion practiced? It is safe to say that the research is not completed. And it is unlikely that there will be a result soon. At the moment, the safety of using current developments is not 100% ensured. Therefore, we can only wait for progress and believe in science.

The first blood group 0 (I) according to the AB0 system means that human red blood cells are completely devoid of antigens. This means that when transfused, a reaction (antigen + antibody) is not possible; this property is well known in medicine.

The prevalence of people with this group is the highest. They number up to 33% of the world's inhabitants, in some territories - half of the population.

Origin of blood group 1

400 centuries ago, it was people with this blood type who began to be called “human”. They laid the foundation of our civilization. Although at that time they did not differ in special mental abilities. But they were able to ensure the survival of their family. The main activity is hunting animals. It was physical strong people. They did not know how to negotiate; those who disagreed were immediately destroyed.

No democracy was allowed. People with the first group were the founders of the principle “those who are not with us are against us.”

Who can have children with the first group

The fetal blood type depends on genetic preferences for maternal or paternal characteristics.

The first group is formed if:

  • both mother and father have the same group - the first;
  • at least one of the parents is the owner of the first group, and the other - the second or third.

If a parent with group 4 has AB antigens, the baby will definitely get one of them. Therefore, geneticists know that the combination of the first and fourth groups does not give the fetus the first group.

Rh compatibility problems

Rh in the blood is considered as an additional erythrocyte antigen. It is either present (Rh+) or absent (Rh-).

If both parents have blood type 1 Rh-negative, then the baby will also be (Rh-). In conditions where only one of the parents does not have the Rh factor, the probability of having a Rh positive and Rh negative baby is divided equally.

Rh compatibility matters for birth healthy child and the course of pregnancy, as well as if blood transfusion is necessary for a patient with the first group.

Family happiness depends on timely examination of parents

Implications for pregnancy

During pregnancy, for women without an Rh factor in the blood, compatibility with the Rh factor of the fetus is important. And this depends on the genes of the child’s father. For an Rh-positive mother, the characteristics of the child’s blood do not matter. The absence of the Rh factor in a woman’s blood can cause an outbreak of conflict with the fetus when the child chooses a positive paternal gene.

By the end of the first pregnancy or immediately during subsequent ones immune cells The mother's body is trying to get rid of the foreign protein.

IN best case scenario the child will be born with many diseases (jaundice, impaired liver function, anemia). During the second pregnancy, placental rejection and early miscarriage occur.

To prevent complications and birth healthy baby parents must take a blood test for group and Rh factor. Timely administration of anti-Rhesus globulin, which binds maternal antibodies, allows the fetus to develop normally and does not interfere with the proper course of pregnancy and the health of the mother.

Implications for blood transfusion

People with the first Rh negative group are considered universal donors. Their blood has no antigens at all. Such blood can be transfused in emergency cases to any person if single-type blood is not available at the moment.

The owner of the first groups will suit only blood of the same group according to the AB0 and Rhesus system. Any excess antigens will cause an intolerance reaction, which will complicate the patient's condition.


Planned blood transfusions are prohibited due to the presence of other individual incompatibility indicators

Character traits

To combat difficulties, people with the first group are endowed by nature with high volitional abilities. Such people become leaders, regardless of what they call the people to. They are able to achieve a goal without worrying about moral characteristics.

The study of character traits made it possible to establish the presence of increased emotionality and a developed sense of self-preservation. Such qualities of a leader allow him to calculate the degree of risk, think first of all about his own benefit, and analyze the result of his work.

They do not tolerate criticism and are jealous. They are more likely to be suited not for professions, but for positions with a leadership focus.

What to watch out for

Typical pathologies can affect endurance:

  • hypertension with crises;
  • peptic ulcer;
  • decreased function thyroid gland;
  • in males - hemophilia;
  • various allergic manifestations and autoimmune diseases;
  • diseases of the respiratory system, especially the tendency to respiratory infections, influenza, complicated by pneumonia, predisposition to tuberculosis;
  • joint damage (arthritis, arthrosis).

Nutritional Features

The diet for blood group 1 takes into account health risk factors, the typical metabolism of “hunters” and a set of optimal products for the functioning of the digestive system. In addition, attention should be paid to the predisposition of people in the first group to be overweight. Most often this is due to a violation of nutritional principles (this is the opinion of supporters of the blood group diet).

To lose weight, it is recommended to “return” to natural purpose. Opinions on this matter are completely opposite: nutritionists have already proven the inconsistency of this approach to health. But for those who are interested and believe, we offer oriental recommendations for the menu.


Constantly eating meat seriously takes a toll on the family budget

Although modern representatives of the first group do not have to chase animals all day long, defeat a mammoth or participate in a fight with a rhinoceros, they are still considered to need a large amount of animal proteins from meat and fish.

What is possible

All varieties of dark meat, fish, and liver are shown. In second place is the bird. Fish fat helps improve blood clotting, contains Omega 3 unsaturated acids, helps to absorb protein. Others seafood allow you to saturate the body with iodine for the synthesis of thyroid hormones (sea kale).

Protein from dairy products is less digestible, but is essential due to calcium (especially for women). Therefore, people of non-African origin are allowed to eat a little cheese and drink kefir. The same attitude should be towards eating eggs.

Buckwheat is a useful cereal. Vegetables and fruits are necessary in large quantities: pineapples, spinach, broccoli, radishes, parsley. Only rye bread. Best drink- green or herbal tea.

What not to do

All legumes are contraindicated (it is believed that they are less harmful to Asian residents due to established cultural traditions), and corn. You can include some legumes (beans, peas, lentils) in food recipes to improve digestion, but do not make them the main dish.


Not everyone is able to withstand the position of leader

What to pay attention to during treatment

Due to the tendency to blood clotting disorders, medications containing aspirin and Gingko Biloba should be taken with caution. To protect the intestines, it is recommended to use probiotics to maintain intestinal flora.

Herbal treatment works well for people with the first blood group. Soothe decoctions of mint, rosehip, tinctures with lime color, ginger. Not recommended: aloe in different forms, tinctures of burdock, corn silk.

Psychologists advise people with blood type O to stop fussing and fight narcissism and arrogance towards others. You should not rush things and seek power at any cost. This can lead to total loneliness.

Blood is a liquid that has a number of individual, evolutionarily determined characteristics. Some of them, designated as blood groups and Rh factor, are taken into account during blood transfusions and other types of transplantation of donor material.

Also for people with various groups certain characteristics of character and health are attributed to blood.

Blood groups and their features

Human blood groups are a classification that takes into account the characteristics of erythrocytes - red blood cells. Information about them, as well as about rhesus, made it possible to begin transfusing blood from person to person with a minimum of risks: before the discovery, attempts at blood transfusions ended in the deaths of recipients - people who receive donor material.

Human blood groups were discovered by Karl Landsteiner, a famous scientist from Austria, who received for his research

Nobel Prize. The discovery was made in 1900, and 40 years later, in 1940, humanity learned that blood has the Rh factor, and this characteristic was also discovered by Landsteiner together with three students.

His research gave people the opportunity to understand what blood is like and use this information to save lives.

The red blood cell proteins that define the group are called antigens.

The absence or a certain combination of antigens makes it possible to determine a person’s blood type. There are only two of these protein compounds; they are given letter names: A and B. They trigger the reaction of producing special antibodies - agglutinins.

When determining blood types in the laboratory, a reaction is triggered, and its results allow laboratory technicians to determine the characteristics of the blood.

  • Group I. There are no antigens, agglutination does not start with any of the coliclones.
  • Group II. Antigen A is present in the blood, reaction with zoliclon anti-A positive, there is no reaction with other zoliclones.
  • III group. Antigen B is present in the blood, the reaction with anti-B tsoliclone is positive, but there is no reaction with other tsoliclones.
  • IV group. Both antigens are present in the blood; the reaction with both types of cyclones is positive.

Coliclones - a solution containing monoclonal antibodies placed on outside red blood cells

How many groups does a person have?

There are six human blood groups, which are of key importance in blood transfusions. But various researchers have expanded this list to 33, depending on the characteristics of protein compounds and their combinations.

In the future, the list of blood types will expand even more.

In 2012, researchers discovered two additional groups human blood, which are also taken into account during transfusion: Junior and Langereis. The fifth and sixth groups are most often found among Gypsies and Japanese.

In the practice of blood transfusions, the approach in which blood is divided into four types is still relevant, and rare species blood are not taken into account in all cases, with the exception of those situations where transfusion of inappropriate material is fraught with serious complications (serious condition of the recipient, certain diseases).

How are each blood group spelled?

The AB0 system is widespread throughout the world, in which blood groups are designated by letters and numbers, depending on the presence and characteristics of antigens:

  • Type I - 0, since there are no antigens;
  • Type II - A;
  • III type - B;
  • Type IV - AB.

What other group classifications are there?

Research in the field of hematology is gradually expanding the list of classifications that are taken into account during blood transfusions and can reduce the likelihood of developing both quickly occurring and delayed complications.

There are the following additional systems identification:

NameDescription
KellThe factors included in this classification follow Rhesus and the ABO system in terms of immunogenicity. This means that it is impossible not to take into account the peculiarities of these antigens during transfusions: this will end disastrously for the recipient. The classification is taken into account not only for blood transfusions, but also when monitoring the course of pregnancy in cases where the risk of an immune conflict is increased. There are two specific proteins in this system, and they are designated by the letters: “k” and “K”.
DuffyIn terms of the severity of the immune response, it follows the Kell system, but to the development hemolytic disease During pregnancy, these protein compounds do not result. Complications may develop during blood transfusions.
KiddContains two antigen proteins that form three possible varieties. They do not lead to severe immune reactions if uncontrolled, but can still lead to some complications. Few people have them.
MNSsIt has four factors that give a total of nine genotypes. Belongs to the most difficult categories. Antibodies are inactive, but in some cases lead to hemolytic disease and complications during transfusions.
LutheranThis type of antibody is rare and inactive: immune reactions associated with it have not been identified.
LevisIt includes two types of antigens that form three phenotypes and rarely lead to complications.
Vel-negativeIt is rare and can lead to significant complications, especially in the presence of severe diseases. The protein compound was discovered in 2013, but medicine encountered incompatibility due to it earlier.

Clinics that do not specialize in hematology do not have the ability to thoroughly determine blood characteristics. And usually this is not necessary: ​​the classical AB0 and Rh systems are sufficient for transfusions.

What is the Rh factor?

Rh factor is the name for a number of erythrocyte antigen proteins that influence the occurrence of various immune reactions. This indicator is taken into account during transfusion (transfusion) activities so as not to jeopardize the life and health of the recipient (the person receiving the transfusion).

There are 50 types of rhesus antigen proteins, but six of them are of key importance. Central protein - D.

Briefly about protein D:

  • It causes Rh conflict during pregnancy;
  • Its absence or presence is defined as “negative” (Rh-) or “positive” (Rh+) group membership;
  • Present in 85% of people on the planet.

When transfusing, Rhesus values ​​are always taken into account: if you transfuse to a person without an antigen protein positive blood, this will lead to severe consequences and can result in death.


Distinguishing Antigones in humans

Antigens are present not only in red blood cells, but also in other cellular elements of the blood:

  • Platelets. They are similar to epitopes (part of an antigen molecule) of erythrocytes, but the severity of their reactions is reduced during research, so they are not used in laboratories to determine the characteristics of the material.
  • Plasma proteins. More than ten varieties of them have been found.
  • Nuclear cells, this is especially true for lymphocytes. The discovery of antigens of these cells made it possible to increase the safety of tissue and organ transplantation, and to make a number of discoveries in genetics (the field of hereditary diseases).

The number and characteristics of the set of specific proteins vary from person to person, but some rare blood types are more common in certain countries of the world. For example, there are more Kell-positive people in England (8.66%).

How are human blood types determined?

Methods for determining human blood groups in the laboratory:

  • Standard. Used in most clinics. Capillary blood is separated, mixed with four types of special serums and after 5 minutes the results of the reaction are looked at. If the reaction is nonspecific, additional studies may be required.
  • Cross reaction. Used to clarify the result when standard method if the reaction was nonspecific. Donor red blood cells with certain characteristics are mixed with the patient’s material, the result is also ready after 5 minutes.
  • Colicloning. This method is characterized by increased accuracy: instead of classic serums based natural blood zoliclones are used ( saline solution monoclonal antibodies to antigens located on the surface of human red blood cells).
  • Express method. Suitable for those cases when there is no possibility to use other methods, and there is an urgent need to find out the characteristics of the blood. Apply special sets with cards containing dry antibodies in the wells. Blood is applied to them, and its characteristics become known after 3 minutes.

To determine Rh, blood from a vein and two types of serum are used. Serum is added to the material, and then it is placed in a laboratory type of water bath for ten minutes.

Blood type compatibility

Compatibility rules. This information will make it possible to understand how many blood groups are suitable for other types of transfusion.

RecipientDonor material
I, Rh-I, Rh+II, Rh-II, Rh+III, Rh−III, Rh+IV, Rh-IV, Rh+
I, Rh-+
I, Rh++ +
II, Rh-+ +
II, Rh++ + + +
III, Rh−+ +
III, Rh++ + + +
IV, Rh-+ + + +
IV, Rh++ + + + + + + +

But later more and more new factors were discovered that were important to take into account. Now in medical institutions They transfuse blood to patients, which is pre-tested for compatibility and fully corresponds to their basic characteristics.

IN in some cases material from universal donors is used, but this usually happens when there is no access to suitable material, and action needs to be taken as quickly as possible.


Hematologist - medical specialist involved in an area that is related to circulatory system.

He knows everything about human blood groups and treats diseases in which hematopoietic structures do not function correctly.

Complications of transfusion of inappropriate donor material

If the patient is transfused with inappropriate blood, acute hemolysis develops (destruction of red blood cells with the release of environment hemoglobin), in which pronounced disturbances in the coagulation processes, acute abnormalities in kidney function and circulatory shock are observed.

If the patient develops hemolysis, he requires urgent infusion therapy.

The severity of complications depends on the amount of material transfused and the health status of the recipient.

What determines the inheritance of human blood groups?

Mechanisms of inheritance of human blood groups:

  • I gr. If both parents have this group, the child will be born with it one hundred percent. It is also obtained by combining I and II, I and III, II and II, III and III.
  • II gr. Obtained by combining I and II, I and IV, II and II, II and III, II and IV, III and IV, IV and IV.
  • III gr. Combinations I and III, I and IV, III and IV with a 50% chance lead to the birth of a child with the third variety. Highest probability(75%) is obtained by combining III and Group III. Combinations II and III, II and IV, IV and IV - 25% probability.
  • IV gr. Combinations II and III, II and IV, III and IV - 25% possibility. If both parents have the fourth group, the child will receive it with a 50% probability.

If one parent had the fourth type of blood, the child would not be born with the first. And a child with the fourth cannot be born if one of the parents is a carrier of the first.

  • I- leadership abilities, organizational skills, energy. These people are strong-willed and strong, strive to reach maximum heights, but are prone to excessive aggression and selfishness.
  • II- patience, calmness and balance are inherent in people with this type of blood. These individuals have a keen sense of the world, love comfort, but are prone to self-hatred, and their judgments are not always flexible.
  • III- love of creativity, desire for knowledge. These people are distinguished by a philosophical outlook on life. They cannot stand routine, monotony, everyday life, and are prone to depression.
  • IV- gentleness, balance, pleasant character. These people are friendly, communicative, tactful, but they find it difficult to make decisions.

How should people from different groups eat?

Traditional medicine does not support the selection of diets for blood types, but ideas about what foods are suitable for which group may be of interest.

  • I - meat eaters. They are instructed to give preference to meat, dairy products and refuse baked goods.
  • II - vegetarians. Complete refusal from meat is inadvisable: the creators of the theory report that people in this group are recommended to exclude from their diet fatty meat cooked with big amount spices Seafood and plant foods are beneficial.
  • III - mixed food. Any food is suitable for them: meat and herbal products. A well-chosen diet will reduce the risk of diseases in old age.
  • IV - moderately mixed food. Both meat and plant foods suit them well, but it is recommended not to overeat and avoid junk food.

Where can I find out my blood type?

Information about blood can often be found in medical card, just go to the therapist and ask him to take a look. If it is not available, you can take a test in public clinics, the referral for which will be given by a therapist.
