❤ What is the difference between different blood types, what is the Rh factor and does it all affect health and character.

Blood type can tell you a lot about a person. As a rule, it determines his character. The blood type remains unchanged throughout life, performing its main function, which is to support the vital functions of the human body.

Thus, a man and a woman must have perfect compatibility before planning a child. Blood type 4 positive is considered the rarest. It consists of AB antigens. Among the people it is also called mixed.

What is the Rh factor?

Rh factor (Rh factor) is a blood protein that is found on the surface of blood cells - red blood cells.
If this protein is present, then this means that the person has a positive Rh factor, but if it is not there, then it is negative. Rh factor is determined by antigen. There are five main antigens, but it is the D antigen that indicates Rh. 85% of the world's population have positive Rh factors. How to determine your Rh factor? It is enough to donate blood from a vein just once. This indicator does not change throughout life. The Rhesus status of the embryo is formed already in the first trimester of pregnancy. Determining this indicator is very important for the expectant mother, since in the case of an Rh-negative mother and an Rh-positive child, various pregnancy complications are possible. In this case, it will be especially important to follow the doctor’s instructions, avoid infectious and colds, as well as stress. Also on various websites there are so-called calculators that determine the Rh factor of the unborn child. It must be remembered that blood is donated on an empty stomach. A rapid Rh test can be taken at any independent laboratory where blood is taken (for example, Invitro). The price depends on the price list of the clinic itself. You can find out about the cost of the analysis immediately before delivery. You can also donate blood and find out your Rh factor for free if you become a donor. To do this, you need to fill out a form to register yourself as a blood donor at the appropriate institution.

The Rh factor also plays a big role in blood transfusions. A transfusion involves two people: the recipient (the one who receives the blood) and the donor (the one who donates the blood). If the blood is incompatible, the recipient may experience complications after the transfusion.

The most common myth among couples is that blood type (like the Rh factor) is inherited from a man. In fact, the inheritance of the Rh factor by a child is a rather complex and unpredictable process, and it cannot change during life. But it is worth remembering that in rare cases (about 1% of Europeans) a special type of Rh factor is determined - weakly positive. In this case, Rh is determined either positive or negative. This is where questions arise on forums: “why did my Rh minus change to plus?”, and legends also appear that this indicator may change. The sensitivity of the testing method plays an important role here.

An equally popular search on the Internet is “horoscope by blood type.” For example, in Japan, great attention is paid to deciphering blood type. Believe it or not - it's up to you.

In the world there is such a thing as a medical tattoo, photos of which can be easily found on the Internet. What do these tattoos mean and what are they for? Its designation is quite pragmatic - in case of a serious injury, when an urgent blood transfusion or surgery is required, and the victim is not able to give the doctor information about his blood type and Rh. Moreover, such tattoos (a simple application of the blood type and Rh factor) should be in places accessible to the doctor - shoulders, chest, arms.

Some facts

Representatives of the fourth blood group in question are distinguished by their endurance. They can easily adapt to completely new climate and living conditions. In addition, such people calmly tolerate changes in diet. Therefore, the diet is not scary for them.

Resistance to all kinds of diseases is also observed. As for the digestive system, it is sensitive in owners of blood group 4. Therefore, most people require a diet. Another well-known fact is that Jesus Christ had the fourth blood type. True, there is no exact confirmation of this.

The characteristics of people of this blood group are as follows. They are calm, tactful, balanced and friendly. In addition, such a person has sociability, he will easily get along with other people. Sadness and depression visit him quite rarely.

Despite the external positivity and balance, the inner world of these people is full of worries. They are often afraid of making mistakes and making the wrong decision. Sometimes it is quite difficult for them to decide something. In order to suppress anxiety within oneself, active mental activity is used, various physical activities are performed that can take away a large amount of energy. People with blood type 4 are subject to mysticism. Thus, they are often able to foresee various events.

The fourth blood group, as a rule, belongs to creative people.

The following plays a big role in their lives:

• emotionality;
• fantasy;
• perfect taste;
• sincerity;
• love for everything beautiful;
• developed intuition.

Due to their sophisticated perception of reality, such people are capable of going to extremes. Under the influence of intense emotions, they sometimes fail to gain control over themselves. A person who has compatibility of A and B antigens often creates idols for themselves. They are characterized by absent-mindedness, impracticality, they are not always ready to solve problems that arise, and are sensitive to insults.

Rh factor and pregnancy

Compatibility of Rh factors during pregnancy is one of the tests that is carried out in the antenatal clinic. When a woman registers with a gynecologist, she will need to donate blood to determine her group and Rh factor. It can significantly affect the course of the next nine months. If the baby inherits the positive Rh of the father, and the mother has a negative Rh, then the protein in the child’s blood is unfamiliar to the mother’s body. The mother's body "considers" the baby's blood a foreign substance and begins to produce antibodies, attacking the baby's blood cells. If there is a Rhesus conflict during pregnancy, the fetus may experience anemia, jaundice, reticulocytosis, erythroblastosis, hydrops fetalis and edematous syndrome of the newborn (in the latter two cases there is a high probability of death of the child).

Boy or...

For many centuries, the blame for the lack of an heir in the family was placed on the woman. To achieve the goal of having a boy, women resorted to diets and calculated favorable days for conception. But let's look at the problem from a scientific point of view. Human sex cells (eggs and sperm) have half the set of chromosomes (that is, there are 23 of them). 22 of them are the same for men and women. Only the last pair is different. In women these are XX chromosomes, and in men they are XY.

So the probability of having a child of one sex or another depends entirely on the chromosome set of the sperm that managed to fertilize the egg. To put it simply, the father is entirely responsible for the gender of the child!

Blood type and Rh factor: compatibility

The cause of incompatibility may be not only Rh blood type, but also blood type.

What are the different blood types? They are distinguished by the presence of specific proteins.

Four groups:

• the first (occurs most often) - O - there are no specific proteins in it;
• the second - A - contains protein A;
• the third - B - contains protein B;
• the fourth (the rarest of all) - AB - contains both type A and type B proteins.

First

(Rh negative) can provoke a conflict in the mother:

• for protein of the second group (A);
• for protein of the third group (B);
• for Rh protein (positive).

Second

(Rh negative) can provoke a conflict in the mother:

• for protein of the third group (B);
• for protein of the fourth group (B);
• for Rh protein (positive).

Third

(Rh factor is negative) the mother can provoke a conflict:

• for protein of the second group (A);
• for protein of the fourth group (A);
• for Rh protein (positive).

Fourth

does not conflict with any other group. The only case when an immune reaction is possible is if the mother has group IV and is Rh negative, and the father is positive.

Key Strategies

People who have compatibility of A and B antigens in their blood should adhere to the following recommendations:

• express social activity, try to avoid situations of intense competition;
• create a plan of tasks that need to be solved over a certain period of time and strictly follow it;
• you need to change your lifestyle slowly;
• It is advisable to do physical exercise or some kind of sport, stretch, it is recommended to give preference to yoga or meditation;
• take an active part in social activities;
• find time to be alone with yourself;
• conduct exercises in psychological visualization techniques every day;
• If there are malfunctions in the digestive system, you must consult a doctor, who will develop a special diet.

People who have blood type 4 of any Rh factor lack disciplined decisions. However, it must be noted that each person is an individual. He creates himself on his own. In many ways, everything depends on the influence of the society in which he lives.

Thus, it is not so important what kind of blood a person has. The main thing is what are the goals set for him. It is also important to determine for yourself ways to achieve them. The information presented gives only a general idea about people with the fourth blood group. The rest depends on the person himself, his character, characteristics and willpower.

Rh positive during pregnancy

If you are Rh positive, then your husband’s Rh negative will not affect the course of your pregnancy. In the case when a child inherits a negative Rh factor, there is no protein in his blood that is “unfamiliar” to the mother’s immune system, and a conflict will not arise.

• Rh-positive mother + Rh-positive father = Rh-positive fetus
  The child has inherited the positive Rh factor of the parents, and the pregnancy will pass without complications.
• Rh-positive mother + Rh-positive father = Rh-negative fetus
  Even if the parents' Rh factor is positive, the baby can be negative. In this case, we can still talk about the compatibility of Rh factors during pregnancy: the mother’s body is “familiar” with all the proteins in the child’s blood.
• Rh-positive mother + Rh-negative father = Rh-positive fetus
  Both the mother and the fetus are positive, and there is no conflict during pregnancy.
• Rh-positive mother + Rh-negative father = Rh-negative fetus
  Although mother and fetus have different Rh blood factors (mother and child have positive and negative, respectively), there is no conflict.

As already mentioned, Rh blood is a protein. And since the mother’s body already has this protein, the fetal blood does not contain components unfamiliar to the mother’s immune system.

Table

According to the creators of this method, you can easily find out the sex of a child by blood by comparing the groups of parents in the following table.

Table for determining the sex of a child by blood type

How to calculate?

To determine the sex of your child based on the blood type of the parents, you need to find out the indicators of the parents and find them in the table. The sex of the fetus is located at the intersection of the rows and columns of the table. For example, if the wife has the third (B) group, and the husband has the first (0) group, then the couple will have a daughter. And if both have the third group (B), then you can expect a male child. This may seem like a fairly simple way to determine the sex of the unborn child based on the blood type of the parents, but how reliable is it? Read on.

By Rh factor

According to this method, primary sexual characteristics are also influenced by rhesus, which is also indicated in the table for determining the sex of a pregnant child by blood type.

Table for determining the sex of a child by Rh blood factor

According to this table, it is also easy to find out the gender of the child by blood type by comparing the indicators of the partners. For example, if two parents have the same Rh, then they will only have daughters.

In addition to Rh and the AB0 group, there is another rather interesting method for determining the sex of a child by the blood of the parents. According to it, people's blood is renewed cyclically: in men - every 4 years, in women - every 3 years. And the gender of the spouse, who was “renewed” earlier, is passed on to the baby. For example, if the father’s was “renewed” this year, and the mother’s was three years ago, then the fetus will have male genitalia.

But the test for the gender of the child by blood renewal has a serious drawback: how to find out when this happened last time? Theoretically, the update time can be calculated by date of birth. For example, at the 21st year of life, a woman should undergo the 7th renewal, and a man at the 32nd year of life should undergo the 8th renewal. But this does not mean that the process must begin exactly on your birthday. Although this method of updating the blood of parents to calculate the sex of the unborn child also takes into account transfusions and blood loss, there is no scientific basis for this method.

Can the blood of mom and dad determine the sex of the unborn baby?

So how can you determine the sex of a child based on the blood of the parents and is it even possible to do this? If we are talking about the biological material of the mother, then the primary sexual characteristics of the fetus can be found out, but not with the help of any tables or online calculators. And the male group does not in any way affect the formation of genitalia in the embryo, so any advice and recommendations on how to determine the sex of a child by the blood of the parents have no basis. Why?

Let us remember what the primary sexual characteristics of a person depend on. They are laid at the moment of fusion of the egg and sperm during fertilization. The egg has only an X chromosome, which determines the female sex. The paternal reproductive cell can carry both a female and a male chromosome. If at the moment of fertilization the sex cells of the parents are connected to the X chromosome and the Y chromosome, then there will be a boy. Otherwise there will be a daughter.

How does the antigenic characteristics of blood cells affect this process? Obviously, none. Based on the groups of antigens of the father and mother, it is possible to determine only a similar indicator in the baby, and then with a statistical probability of 25, 50 and 100% according to the summary table.

The type of antigen on the red blood cells in the mother does not in any way determine the sex of the embryo. Therefore, the method of finding out the sex of a child by the blood type of the parents is pseudoscientific and can only serve as entertainment.

Following the logic of this test, all married couples should have either sons or daughters. Then why do families have children of different sexes, including twins? This is a rhetorical question that contains the answer to how to determine the sex of the unborn child by blood type. There is no evidence in official genetics that blood cell antigens have any effect on the embryo.

Another method for calculating the sex of a pregnant child - the parental blood renewal test - is also not scientifically substantiated. There is no medical evidence that red blood cells and plasma are renewed every 3-4 years. Moreover, the life span of an erythrocyte is only 120 days, regardless of the person’s gender.

Rh factor negative during pregnancy

Rh negative during pregnancy is not always a death sentence for the baby. The main thing is that it is the same for both the baby and the mother.

• Rh-negative mother + Rh-negative father = Rh-negative fetus
  The baby inherited the Rh factor of his parents. And since both the mother and the fetus have no protein (Rhesus) in their blood and their blood is similar, then a conflict does not arise.
• Rh-negative mother + Rh-positive father = Rh-negative fetus
  This is one of the cases when the Rh factor is very important: the compatibility of the blood of the mother and the fetus affects the next nine months of intrauterine life. Although a woman is Rh negative during pregnancy, it is good that the fetus is also Rh negative. There is no Rh in either the mother's blood or the fetus's blood.

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. A complete abstinence from meat is impractical: the creators of the theory report that people in this group are advised to exclude fatty meats cooked with a lot of spices from their diet. Seafood and plant foods are beneficial.
• III - mixed food. Any food is suitable for them: meat and plant 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.

Nutrition according to blood types

When does Rh-conflict pregnancy occur?

Rh negative mother + Rh positive father = Rh positive fetus

Please note: no matter what group the mother has, negative Rh during pregnancy becomes a cause of conflict. In this case, the embryo inherits it from the father and brings the “new protein” into the body of the Rh-negative mother. Her blood “does not recognize” this substance: there is no such protein in the body. Accordingly, the body begins to defend itself and produce antibodies. They penetrate the placenta into the baby's blood and attack his red blood cells. The fetus tries to defend itself: the spleen and liver begin to work hard, and they increase significantly in size. If a child has few red blood cells left, he develops anemia, or anemia.

When did it appear?

The history of group 4 is associated with the long development of society and gene mutations. This group is considered the youngest. People with AB blood first appeared in the world about 10 centuries ago. Scientists are considering several hypotheses about the origin of this group.

Researchers found that blood stains of the fourth group were found on the Turin remains. This means that, most likely, Christ was the carrier of such rare blood.

A hypothesis has been put forward that AB (IV) appeared due to interethnic marriages. It is assumed that for the first time children with similar blood characteristics appeared in marriages between Mongols and Europeans. It was not previously allowed to create such families, therefore there was no mixing of blood types giving this group.

Attention! AB (IV) can be inherited by children if the parents have group 2 or 3, but this is not possible if the father or mother has the first group.

There is another theory about how human blood group 4 came about, related to food. Presumably, the composition of the blood is formed and changes according to the principle of mutation. Some geneticists are confident that due to the introduction of new products into the daily diet, such irreversible changes appeared. This means that food that has been chemically processed is responsible for the fourth group. However, this hypothesis does not explain why there are very few such people.

Rh negative during pregnancy

There is a vaccine - anti-Rhesus immunoglobulin, which prevents Rh-conflict during pregnancy. It binds the antibodies that the mother’s body produces and brings them out. Vaccination can be carried out during pregnancy. If you are Rh negative and your husband is positive, this is not a reason to give up motherhood. Over the course of 40 weeks, you will have to donate blood from a vein several times:

• up to 32 weeks - once a month;
• from the 32nd to the 35th week - 2 times a month;
• from the 35th to the 40th week - once a week.

If Rh antibodies appear in your blood, your doctor can detect the onset of a Rh conflict in time. In case of conflict pregnancy, immediately after birth, the newborn is given a blood transfusion: the group and Rh factor must be the same as that of the mother. This is especially important in the first 36 hours of the baby’s life - the mother’s antibodies that enter the child’s body are neutralized when they “meet” familiar blood.

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 hemoglobin into the environment), 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.

When can immunoglobulin prophylaxis be carried out?

To prevent conflict in subsequent pregnancies, women with a negative Rh factor should undergo prophylaxis. This is done after:

• childbirth (within three days);
• abortion;
• analysis of amniotic fluid;
• spontaneous miscarriage;
• ectopic pregnancy;
• placental abruption;
• transfusion.

Remember: if you and your baby’s group and Rh are different, this is not an indication that there will definitely be problems. Group and Rh are just the presence or absence of specific proteins in the blood. The reaction of the body and the development of pathologies in our time can be successfully controlled with the help of medications. Your attentiveness to your body, as well as an experienced doctor, will help you bear a healthy baby.

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 , especially 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 do your chances of conceiving depend on your blood type?

Quite a lot is already known about the influence of blood groups, for example, on the likelihood of developing Alzheimer's disease, cancer, blood clots, etc. However, virtually nothing was known about the effect on fertility. And finally, thanks to the efforts of Turkish doctors, research has appeared in this area.

A study published last week found that men with type O are four times less likely to develop impotence compared to guys with other blood types. Experts from Ordu University in Turkey noted that blood type is as important a risk factor as smoking, excess weight, and high blood pressure. The reason is not clear, but scientists have said that in people with type A blood, the penis has a large number of veins, the lining of which can become damaged, leading to erectile dysfunction.

Blood type also affects female fertility. Girls with the second group are more likely to bear a healthy child for a long time than with the first. Studies have shown that women in the first group quickly deplete their egg reserves early in life. But at the same time, women with type 0 have a lower risk of developing preeclampsia - high blood pressure during pregnancy, which can be dangerous for mother and baby.

Naturally, representatives of the rest of humanity (which, by the way, are a little more than half, because people of the 1st group account for a little more than 40%) should not panic either - a higher probability does not mean a 100% chance. Likewise, representatives of the “happy” group should not relax ahead of time - reduced risk does not mean zero.

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 human blood types that also count for transfusions: 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 types of 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).

Hemolytic disease of the newborn

During pregnancy, Rh compatibility is of great importance. If a mother with a negative factor value develops a fetus that has inherited positive blood from the father, then at a later stage of gestation a Rh conflict often appears.

Some of the positive children's red blood cells can penetrate into the mother's bloodstream, causing her to develop special antibodies - agglutinins. They, breaking through the placental barrier, have a destructive effect on the baby’s red blood cells. When a woman is pregnant for the first time, the amount of antibodies produced in her body is usually small. Their concentration is insufficient to provoke serious pathologies.

And if this is not the first pregnancy (the mother is already sensitized), then the level of antibodies in the maternal blood increases. This happens both after an abortion and after a transfusion of blood that is inappropriate for the factor. Under such circumstances, a Rh positive infant may develop chronic hemolysis (destruction of red blood cells), resulting in severe anemia and accumulation of bilirubin in the blood. Often such babies are born prematurely - premature, and they have jaundice.

Since bilirubin (appearing after the breakdown of hemoglobin) is a dangerous toxic substance, brain pathology can develop at its high concentration. In the worst case, general swelling of the fetus occurs inside the womb. The baby may be stillborn or die without living even a few hours.

Baby in the womb

To save the baby, doctors can resort to completely replacing the child’s blood with donor material that matches the parameters.

Inheritance of traits

For centuries, parents have only wondered what their child would be like. Today there is an opportunity to look into beauty far away. Thanks to ultrasound, you can find out the gender and some features of the anatomy and physiology of the baby.

Genetics allows us to determine the likely color of eyes and hair, and even whether a child has an ear for music. All these characteristics are inherited according to Mendelian laws and are divided into dominant and recessive. Brown eye color, hair with small curls and even the ability to curl the tongue are signs of dominance. Most likely, the child will inherit them.

Unfortunately, dominant signs also include a tendency to early baldness and graying, myopia and gaps between the front teeth.

Gray and blue eyes, straight hair, fair skin, and a mediocre ear for music are considered recessive. These signs are less likely to occur.

Nutrition

The fourth group is not too different in terms of nutrition from all the others. In this case, we can say that it is better not to experiment and not use different product compatibility. Various cereals and moderate consumption of meat are suitable as the main diet. There are no special restrictions on who can do what, because the main thing is to eat a moderate amount of fatty meat. If you do not adhere to this, you can provoke the development of anemia.

It is also worth noting that excessive consumption of all vegetables, herbs and seaweed serves as a good prevention of cancer. There is no specific diet for blood group 4, because such people can consume a wide variety of balanced diets.

The main thing is that such compatibility is acceptable. For example, you should not eat the main dish for lunch and wash it down with milk. This can lead to excess weight, and the 4th blood group is exactly what it is prone to. A diet like this can lead to digestive tract problems, including colon disease.

The nutritional pattern of blood type 4 depends even more on sports, so you shouldn’t be lazy, but regularly engage in at least minimal exercise. It could be as simple as getting up two stops ahead of your assigned seat. More often go up on foot rather than by elevator and the like. Such movements for AB type are very progressive, since these people are less inclined to be overweight. Skiing, skating or rollerblading will be beneficial.
