Are the first positive and the second positive compatible? What you need to know about blood type compatibility in sexual and family relationships
Issues of blood compatibility are a hot topic in modern medicine. It gained its significance with the development of immunohistochemistry and genetics, which were able to substantiate the paradoxical cases occurring in medicine.
What is blood type
The test must be taken in order to find out the genetic predisposition to pathologies and identify compatibility by blood groups. An increased level of white blood cells will reveal the presence of an inflammatory process or infection. Red blood cell counts that deviate from the norm will help determine if body systems or organs are functioning improperly.
Knowing your blood type will help you quickly find a suitable donor or become one yourself. Also, blood compatibility will be a decisive factor if a woman tries to get pregnant.
Blood has the following composition:
- Plasma;
- Platelets;
- Red blood cells;
- Leukocytes.
Previously, people had only one blood type, but over time, man had to adapt to the environment through mutation. And today there are 4 blood groups.
Blood group discovery table
As a result of the study of red blood cells, special proteins (antigens A, B) were identified in some, the presence of which means that the carrier belongs to one of the III blood groups. Later a fourth group was identified.
In 1904, a new discovery was made - the Rh factor (negative - Rh-, positive - Rh+), which is inherited by one of the parents. Based on the information obtained, a classification was developed, expressed in the AB0 system. The table below shows the existing blood types.
| Blood group designation | Opening | Diet features | Personal qualities | Place and time of occurrence |
|---|---|---|---|---|
| First I (0) | Meat food | Physical strength and courage | About 40 thousand years ago | |
| Second II (A) | Karl Landsteiner – 1891, Australia | Vegetarianism | Community | Western Europe |
| Third III (B) | Karl Landsteiner – 1891, Australia | Mono-diet is not recommended | Perseverance and patience | India, Pakistan, Himalayas |
| Fourth IV (AB) | Decastello, 1902 | Drinking alcohol is prohibited | Resistance to allergic reactions | As a result of mixing II (A) and III (B) blood groups about 1 thousand years ago. |
The concept of Rh factor
The set of antigens or proteins that make up any tissue determines the specificity of the organism. Regarding blood and red blood cells, these are antigenic surface complexes, one of which is the Rh antigen or Rh factor. According to its presence, people can be divided into antigen carriers (Rh+) and people who do not have the Rh antigen (Rh-).
All situations in life associated with the need to mix blood are determined by the ability of the blood to maintain its structure after such a procedure. This largely depends on the Rh compatibility factor.
Something to remember! Blood compatible with the Rh factor is blood that the body will perceive as its own. This means that only blood with an identical Rh factor can be such!
Blood groups and their compatibility
The theory of blood group compatibility was developed in the mid-twentieth century. Since then, the procedure of blood transfusion (hemotransfusion) has been used to restore blood volume, replace certain of its components (plasma proteins, leukocytes, red blood cells), to restore pressure, for burns, infections, and hematopoietic aplasia. To receive a blood transfusion, your Rh factor and blood type must be compatible.
There is a rule that determines blood compatibility: donating red blood cells should not be agglutinated by the recipient's plasma.
So, if the same agglutinogens and agglutinins (A and α or B and β) occur, the process of sedimentation and further hemolysis (destruction) of red blood cells starts. Being the main mechanism for oxygen transfer, the blood stops its respiratory function.
It is believed that the first I(0) blood group is universal, and it can be transfused to people with any blood group. Blood group IV (AB) is a universal recipient, that is, carriers of this blood group have the ability to accept blood of any group. In practice, the rule of exact compatibility is usually followed, transfusing blood taking into account the Rh factors of the recipient's blood.
During transfusion, the compatibility of the blood groups of the recipient and the donor determines the success of the blood transfusion procedure. In the absence of compatibility, agglutination will occur (this is the gluing of red blood cells, which leads to the formation of blood clots, which can cause death).
Blood group compatibility table for transfusion:
| Blood group | Recipients | From which donors can a transfusion be given? |
|---|---|---|
| I (0) | I (0) | |
| II (A) | II (A), IV (AB) | I (0), II (A) |
| III (B) | III (B), IV (AB) | I (0), III (B) |
| IV (AB) | IV (AB) | I (0), II (A), III (B), IV (AB) |
From the table above, the following practical conclusions can be drawn:
- Carriers of the first blood group are universal donors, but they themselves can only be recipients of the first blood group;
- People with blood group IV are universal recipients, although they themselves can only be donors for people with group IV;
- Donor compatibility is achievable only if the donor's blood does not contain red blood cells with antibodies that will provoke their destruction after blood transfusion.
Something to remember! Compatibility for the Rh factor is determined only in 2 cases, regardless of belonging to any blood group: people with a negative Rh factor can only receive Rh-negative blood, and for recipients with a positive Rh factor, they can become Rh-negative , and Rh-positive donors!
First blood group
It is the first negative (positive) group that is considered the foundation of civilization. Our ancestors had the habits of excellent hunters, they were ready to spend all their strength to achieve the goal - this was reflected in the character traits of carriers of this blood type. Modern owners of the first group need the ability to plan actions in order to avoid rash actions.
Characteristics of carriers of the first blood group:
| Characteristic | Signs |
|---|---|
| Character Traits | extroversion; |
| organizational skills; | |
| natural leadership. | |
| Strengths | physical endurance; |
| high ability to survive; | |
| strong digestive system. | |
| Weaknesses | increased acidity (increased risk of developing peptic ulcers); |
| poor blood clotting; | |
| predisposition to arthritis and allergies. |
Second group
Gradually, evolution moved forward, as a result of which people began to engage in more farming. Vegetables and fruits began to be used for food - the human digestive system began to adapt to new environmental conditions. Vegetable protein became the main source of energy for humans - this is how the “vegetarian” blood group appeared - the second positive (negative).
Characteristics of carriers of the second blood group:
Third group
When stressed, the body of a group III carrier produces an increased amount of cortisol, so they usually experience a lack of motivation. It is difficult for carriers of blood type III to experience a violation of internal balance and balance in the team.
Characteristics of carriers of the third blood group:
| Characteristic | Signs |
|---|---|
| Character Traits | versatility; |
| openness to people; | |
| flexibility in decisions. | |
| Strengths | a penchant for creativity. |
| easily tolerate changes in diet; | |
| strong immunity. | |
| Weaknesses | lack of self-confidence and motivation; |
| increased susceptibility to autoimmune diseases. |
IV blood group
Carriers of the fourth blood group appeared as a result of the symbiosis of II and III. They quickly get tired of solving everyday issues and have a penchant for creativity. This is the rarest blood group - only about 6% are carriers.
Characteristics of carriers of the fourth blood group:
Pregnancy and compatible blood groups
There is no controversy about the need for such an area of obstetrics as family planning. It made it possible to significantly reduce the number of unwanted or complicated pregnancies, which was reflected in the birth of a much smaller number of sick children. And one of the aspects of family planning can be called the compatibility of the blood of future parents.
Here it is necessary to consider issues of blood compatibility and immunological compatibility of future parents at conception. These aspects have been confused and discussed as one issue, but they are not. Decisions should not be made on the basis of unreliable information and on the results of only a blood test of spouses for compatibility.
You need to understand that:
- If it is impossible to get pregnant, the compatibility of a husband and wife is determined not by the compatibility of the Rh factor or blood groups, but by the immunological compatibility of a man and a woman. This means that the female body produces antibodies to the components of a particular man’s sperm, and he simply does not perceive it. The Rh factor and blood type have absolutely nothing to do with it;
- A mother with Rh- can give birth to an Rh-positive child. This can only affect the condition of the fetus and the course of pregnancy, but is not regarded as incompatibility for conceiving a child;
- Partners with different Rh factors can have healthy children. There is no need to destroy relationships because the Rh factors of the mother and child may be potentially incompatible. However, you should definitely follow the recommendations that will be given by family planning specialists. Some of these recommendations are listed in the next section.
Combination of blood groups during pregnancy
If a couple decides to have a child, they must control this process at all stages from planning the child to its birth. For conception, blood type is less important than the Rh factor.
The fact is that when an antigen (Rh factor) enters the body, which the body does not have, an immunological reaction occurs when the recipient’s body produces destructive proteins (agglutinins) to the Rh factor. When Rh+ erythrocytes enter the recipient's blood again, gluing (agglutination) and destruction (hemolysis) of the resulting erythrocytes occur.
Rh conflict is the incompatibility of the blood groups of the mother with the Rh-negative group and the Rh+ child, due to which the breakdown of red blood cells is observed in the fetus's body.
Regarding the likelihood of rhesus conflict, you should be careful:
- Spouses whose blood mixing could potentially lead to Rh conflict, with previous pregnancies/births. A positive outcome does not guarantee anything. On the contrary, the likelihood of incompatibility between the blood of the child and the mother increases with each new pregnancy;
- Married couples where the woman is Rh- and the man is Rh+. The maximum probability of developing a conflict pregnancy is 25% when the partner is heterozygous (only 1 chromosome of the pair encodes Rh) and 50% when he is homozygous (each chromosome encodes Rh).
Table of Rh conflict during pregnancy:
| Father's Rhesus | Mother's Rhesus | Probability of Rh factor in newborn | The likelihood of developing Rh conflict |
|---|---|---|---|
| Rh+ | Rh+ | If the parents are heterozygous - 50% positive; | |
| If one spouse is heterozygous and the second is homozygous, 75% positive. | |||
| If both parents are homozygous - 100% positive. | |||
| Rh- | Rh+ | If the Rh positive partner is heterozygous – 25% positive; | The probability of a conflict occurring is less than 50% |
| Rh+ | Rh- | If the Rh positive partner is homozygous – 50% positive. | |
| Rh- | Rh- | The child will be Rh negative in 100% of cases. | There is no conflict pregnancy |
Important to remember!!!
- If the mother's blood is Rh positive, then it is always compatible with the blood of the fetus;
- The possibility of Rh conflict exists only if the mother is Rh negative. The risk is no more than 50%;
- Inheritance of the Rh factor is determined not only by the actual Rh factor of the parents. It also depends on the set of genes that the child inherited, but which did not manifest themselves.

Depending on the types of antigens that make up blood cells (erythrocytes), a specific blood group is determined. For every person it is constant and does not change from birth to death.
The number of red blood cells determines the blood type
Who discovered the human blood type
The Austrian immunologist Karl Landsteiner succeeded in identifying the class of human biological material in 1900. At this time, only 3 types of antigen were identified in the membranes of erythrocytes - A, B and C. In 1902, it was possible to identify the 4th class of erythrocytes.
Karl Landsteiner was the first to discover blood groups
Karl Landsteiner was able to make another important achievement in medicine. In 1930, the scientist, in tandem with Alexander Wiener, discovered the Rh factor of blood (negative and positive).
Classification and characteristics of blood groups and Rh factor
Group antigens are classified according to a single AB0 system (a, b, zero). The established concept divides the composition of blood cells into 4 main types. Their differences are in alpha and beta agglutinins in plasma, as well as the presence of specific antigens on the membrane of red blood cells, which are designated by the letters A and B.
Table "Characteristics of blood classes"
People's nationality or race does not affect group membership.Rh factor
In addition to the AB0 system, biological material is classified according to the blood phenotype - the presence or absence of a specific antigen D in it, which is called the Rh factor (Rh). In addition to protein D, the Rh system covers 5 more main antigens - C, c, d, E, e. They are contained in the outer membrane of red blood cells.
The Rh factor and class of blood cells are established in the child in the womb and are passed on to him from his parents for life.
Method for determining blood group and Rh factor
Methods for identifying group affiliation
Several methods are used to detect specific antigens in erythrocytes:
- simple reaction - standard serum of classes 1, 2 and 3 is taken, with which the patient’s biological material is compared;
- double reaction - a feature of the technique is the use of not only standard sera (compared with the blood cells being studied), but also standard erythrocytes (compared with the patient’s serum), which are pre-prepared in blood transfusion centers;
- monoclonal antibodies - anti-A and anti-B cyclones are used (prepared using genetic engineering from the blood of sterile mice), with which the biological material under study is compared.
Method for identifying blood group using monoclonal antibodies
The very specificity of studying plasma for its group affiliation lies in comparing a sample of the patient’s biological material with standard serum or standard red blood cells.
The sequence of this process is as follows:
- collection of venous fluid on an empty stomach in the amount of 5 ml;
- distribution of standard samples on a glass slide or special plate (each class is signed);
- The patient’s blood is placed parallel to the samples (the amount of material should be several times less than the volume of drops of standard serum);
- blood fluid is mixed with prepared samples (simple or double reaction) or with cyclones (monoclinal antibodies);
- after 2.5 minutes, a special saline solution is added to those drops where agglutination has occurred (proteins of group A, B or AB have been formed).
The presence of agglutination (sticking and precipitation of red blood cells with corresponding antigens) in biological material makes it possible to classify red blood cells into one class or another (2, 3, 4). But the absence of such a process indicates a zero (1) form.
How to determine the Rh factor
There are several methods for detecting Rh-relatedness - the use of anti-Rh sera and a monoclonal reagent (group D proteins).
In the first case, the procedure is as follows:
- the material is collected from a finger (canned blood or red blood cells themselves, which were formed after settling of the serum, can be used);
- 1 drop of anti-Rhesus sample is placed in a test tube;
- a drop of the plasma being studied is poured into the prepared material;
- a little shaking allows the serum to be evenly distributed in the glass container;
- after 3 minutes, a sodium chloride solution is added to the container with the serum and blood cells being tested.
After several inversions of the test tube, the specialist deciphers it. If agglutinins appear against the background of clarified liquid, we are talking about Rh+ - a positive Rh factor. The absence of changes in the color and consistency of the serum indicates negative Rh.
Determination of blood group according to the Rh system
The study of Rhesus using a monoclinal reagent involves the use of coliclon anti-D super (special solution). The analysis procedure includes several stages.
- The reagent (0.1 ml) is applied to the prepared surface (plate, glass).
- A drop of the patient’s blood (no more than 0.01 ml) is placed next to the solution.
- Two drops of material are mixed.
- Decoding takes place 3 minutes after the start of the study.
Most people on the planet have an agglutinogen of the Rh system in their red blood cells. If we look at percentages, then 85% of recipients have protein D and are Rh positive, and 15% do not have it - this is a Rh negative factor.
Compatibility
Blood compatibility is a match by group and Rh factor. This criterion is very important when transfusing vital fluid, as well as during pregnancy planning and gestation.
What blood type will the child have?
The science of genetics provides for the inheritance of group affiliation and rhesus by children from their parents. Genes transmit information about the composition of blood cells (agglutinin alpha and beta, antigens A, B), as well as Rh.
Table "Inheritance of blood groups"
| Parents | Child | |||
| 1 | 2 | 3 | 4 | |
| 1+1 | 100 | |||
| 1+2 | 50 | 50 | ||
| 1+3 | 50 | 50 | ||
| 1+4 | 50 | 50 | ||
| 2+2 | 25 | 75 | ||
| 2+3 | 25 | 25 | 25 | 25 |
| 2+4 | 50 | 25 | 25 | |
| 3+3 | 25 | 75 | ||
| 3+4 | 25 | 50 | 25 | |
| 4+4 | 25 | 25 | 50 | |
Mixing groups of erythrocytes with different Rh leads to the fact that the child’s Rh factor can be either “plus” or “minus”.
- If Rh is the same between spouses (group D antibodies are present), 75% of children will inherit the dominant protein, and 25% will be absent.
- In the absence of specific protein D in the membranes of the mother’s and father’s red blood cells, the child will also be Rh negative.
- In a woman Rh-, and in a man Rh+, the combination implies the presence or absence of Rh in the child in a 50 to 50 ratio, with a possible conflict between the antigens of the mother and the baby.
- If the mother has Rh+ and the father does not have anti-D, Rh will be passed on to the baby with a 50/50 chance, but there is no risk of antibody conflict.
It is important to understand that the Rh factor is transmitted at the genetic level. Therefore, if the parents are Rh-positive, and the child was born with Rh-, men should not rush to question their paternity. Such people simply have a person in their family without the dominant protein D in their red blood cells, which is what the baby inherited.
Blood type for transfusion
When performing blood transfusion (blood transfusion), it is important to maintain the compatibility of antigen and rhesus groups. Experts are guided by the Ottenberg rule, which states that the donor’s blood cells should not stick together with the recipient’s plasma. In small doses, they dissolve in a large volume of the patient’s biological material and do not precipitate. This principle applies to transfusions of vital fluid up to 500 ml and is not suitable when a person has severe blood loss.
People with group zero are considered universal donors. Their blood suits everyone.Representatives of the rare 4th class are suitable for blood transfusion of 1st, 2nd and 3rd types of blood fluid. They are considered universal recipients (people who receive blood infusions).
For patients with 1 (0) positive, class 1 (Rh+/-) is suitable for transfusion, while a person with negative Rh can only be given a zero with Rh-.
For people who have 2 positive, 1 (+/-) and 2 (+/-) are suitable. Patients with Rh- can only use 1 (-) and 2 (-). The situation is similar with 3rd grade. If Rh+ - you can pour in 1 and 3, both positive and negative. In the case of Rh-, only 1 and 3 without anti-D are suitable.
Compatibility at conception
When planning a pregnancy, the combination of the Rh factor of a man and a woman is of great importance. This is done to avoid Rh conflict. This happens when the mother has Rh-, and the child inherits Rh+ from the father. When a dominant protein enters a person’s blood where it is not present, an immunological reaction and the production of agglutinins may occur. This condition provokes the adhesion of the resulting red blood cells and their further destruction.
Blood compatibility chart for conceiving a child
Incompatibility of Rhesus of mother and child during the first pregnancy does not pose any danger, but before the second conception it is better to interrupt the production of anti-Rhesus bodies. The woman is injected with a special globulin, which destroys immunological chains. If this is not done, Rh conflict can provoke termination of pregnancy.
Can your blood type change?
In medical practice, there are cases of changes in group affiliation during pregnancy or due to serious illnesses. This is because in such conditions there can be a strong increase in the production of red blood cells. At the same time, the gluing and destruction of red blood cells slows down. In the analysis, such a phenomenon is reflected as a change in markers in the plasma composition. Over time, everything falls into place.
Blood class, like the Rh factor, is determined genetically in a person before birth and cannot change throughout life.
Diet according to blood type
The main principle of group nutrition is to select foods that are genetically close to the body and allow you to improve the functioning of the digestive system, as well as lose weight.
The first person to suggest taking blood type into account when choosing food was the American Peter D'Adamo. The naturopathic doctor published several books in which he outlined his idea of healthy eating. If you choose the right food, you can forget about poor absorption of nutrients and problems with the stomach and intestines.
Table “Diet by blood type”
| Blood group | Allowed food | Foods to limit as much as possible |
| 1 (0) | sea fish Any meat (fried, stewed, boiled, marinated and cooked over a fire) Food additives (ginger, cloves) All types of vegetables (except potatoes) Fruits (except citrus fruits, strawberries) Dried fruits, nuts Green tea |
Milk and its derivatives Flour products Wheat, corn, oatmeal, flakes, bran |
| 2 (A) | Turkey, chicken Chicken eggs Yogurt, kefir, fermented baked milk Fruits (except bananas) Vegetables (zucchini, carrots, broccoli, spinach are especially valuable) Nuts, seeds |
Wheat and corn porridge Flour products Eggplants, tomatoes, cabbage, potatoes Milk, cottage cheese |
| 3 (B) | Fatty fish Milk and dairy products Spices (pepper mint, ginger, parsley) |
Chicken meat Buckwheat porridge Lentils |
| 4 (AB) | Sea and river fish Soy products Cottage cheese, yogurt, kefir Broccoli, carrots, spinach Pickled cucumbers, tomatoes Sea kale |
Chicken, red meat Fresh milk River white fish Buckwheat, corn porridge |
A group diet involves limiting alcohol and smoking. An active lifestyle is important - running, walking in the fresh air, swimming.
Character traits by blood type
Blood type affects not only the physiological characteristics of the body, but also the character of a person.
Zero group
In the world, about 37% are carriers of blood group zero.
The main features of their character are:
- stress resistance;
- leadership skills;
- determination;
- energy;
- courage;
- ambition;
- communication skills.
Holders of the zero group prefer to engage in dangerous sports, love to travel and are not afraid of the unknown (they easily take on any job, learn quickly).
Temperamental shortcomings include hot temper and harshness. Such people often express their opinions unceremoniously and are arrogant.2nd group
The most common group is considered to be 2 (A). Its bearers are discreet people who are able to find an approach to the most difficult personalities. They try to avoid stressful situations and are always friendly and hardworking. Owners of group 2 are very economical, conscientiously perform their duties and are always ready to help.
Character flaws include stubbornness and the inability to alternate work and leisure. It is difficult to motivate such people to do any rash actions or unexpected events.
3 group
A person whose blood is dominated by group B antigens has a changeable nature. Such people are characterized by increased emotionality, creativity and independence from the opinions of others. They easily travel and take on new things. In friendship they are devoted, in love they are sensual.
Negative qualities often include:
- frequent mood swings;
- inconstancy in actions;
- high demands on others.
Those with blood type 3 often try to hide from the realities of the world in their fantasies, which is not always a positive character trait.
4 group
Speakers of group 4 have good leadership qualities, which is manifested in the ability to negotiate and be collected at a crucial moment. Such people are sociable, easily get along with others, moderately emotional, multifaceted and intelligent.
Despite many advantages in character, representatives of group 4 often cannot come to a common decision, suffer from duality of feelings (internal conflict) and are slow-witted.
The specific composition of the blood and the presence or absence of a dominant factor (antigen D) in it is transmitted to a person with genes. There are 4 blood groups and the Rh factor. Thanks to the classification according to the AB0 and Rh system, specialists have learned to safely transfuse donor blood, determine paternity and avoid Rh conflict during the birth of a child. Each person can check their group affiliation in the laboratory by donating biological material from a finger or vein.
People fall in love with each other, get married, start a family, dream of a child... But, unfortunately, sometimes it happens that a couple is unable to conceive a baby, although both spouses are absolutely healthy. Why is this happening?
In medicine, such situations are called incompatibility during conception. The following types of incompatibility exist:
- immune - by blood group/Rh;
- genetic - the birth of children with or with another disability from absolutely healthy parents.
Does this diagnosis become a death sentence for a married couple or do the spouses still have a chance to conceive an heir? And what is this - incompatibility at conception?
Causes of incompatibility during conception
The number of infertile marriages around the world is increasing every year. In Russia itself, approximately 15 percent of married couples cannot conceive a child due to infertility of one spouse or both. The causes of infertility are distributed almost equally between both spouses: one third of cases are associated with women, one third with men, the last third is due to joint projects (20%) and unexplained cases (10%). Research from medical practitioners and scientists indicates the presence of psychogenic changes and psychological trauma in all situations of infertility.
A marriage is said to be infertile when a married couple who have regular sex life does not achieve the desired pregnancy within a year. At the same time, the spouses do not use any type of contraception.
Immunological incompatibility at conception
In such cases, couples are often given the disappointing diagnosis of “immunological infertility.” Although even with such a diagnosis, conception is still possible, in the absence of constant medical supervision and appropriate treatment, pregnancy is terminated in most cases.
First of all, if there is a suspicion of immunological incompatibility of a particular couple, the man must be examined, for which he will have to donate seminal fluid for examination (). This should be done in clinics specializing in family planning. The results of this analysis will determine the number and motility of sperm, as well as evaluate other equally important sperm parameters. In addition, they will confirm or, conversely, refute the presence of inflammatory diseases in the organs of the male genitourinary system.
So what is immunological infertility?
This means that the immune system of a particular woman produces antibodies that destroy the sperm of a particular man. Recent studies show that in approximately 30 percent of cases the cause of infertility in marriages is precisely this form of infertility or the so-called incompatibility factor. We are talking about some kind of allergy to a man’s sperm, or, strange as it may sound, an allergic reaction of the man himself to his own seed. The reason for this is too high the amount of so-called “anti-sperm antibodies”, which prevent the sperm from performing its fertilizing function. They can be formed in the body of both men and women.
Antisperm antibodies not only prevent conception, but also affect the course of pregnancy.
So why does an “allergy” arise to a specific person? And why does the level of antisperm antibodies increase?
Antisperm antibodies are the culprits of incompatibility
There is a scientific opinion that the risk of developing these antibodies in a woman is directly proportional to the number of her sexual partners. Previous sexually transmitted infections can also be an unfavorable factor. But still, the main reason for the appearance of antisperm antibodies in the female body is a specific immune reaction to the semen of a particular man. Both our psyche and brain contribute to this, which directly influence the most subtle mechanisms of the body, incl. and on the reactions of the immune system itself.
The presence of a certain amount of these antibodies in a woman’s body can lead to toxicosis, spontaneous abortion or delay in fetal development. Therefore, both spouses must undergo an immunological compatibility test.
Often the reason for the inability to conceive is additional complications in the form of a bicornuate uterus, ovarian malformation or cervical hypoplasia.
Rh conflict and incompatibility at conception
Incompatibility at conception is also possible if spouses have different Rh factors. To successfully conceive a child, both spouses must have the same - positive or negative.
If the Rh factors are different, then problems may arise not only when conceiving a child and during pregnancy, but also after its birth (meaning the health of the newborn).
If spouses with different Rh blood factors decide to give birth to a child, they must undergo a course of special therapy before conception so that the mother’s body does not subsequently reject the fetus. It should be noted that a healthier child is born to those couples where the father’s blood type is higher than that of the mother.
But there is always hope
Under no circumstances should you despair. Even in such situations, there is a fairly high chance of becoming pregnant and bearing your first child. However, with subsequent pregnancies a number of difficulties may arise.
In some cases, the immunological mechanism of the mother's body may begin to produce antibodies against the father's Rh factor. As a result, maternal antibodies penetrate the placenta and begin to attack the red blood cells of the fetus, thereby causing the development of anemia.
From a genetic and immunological point of view, spouses with different blood groups, but having the same RH (negative or positive), are considered well compatible. But married couples who have the same blood type, but different Rh factors, are very likely to experience incompatibility during conception.
Compatibility test
If the spouses are unable to conceive a baby for a long time, they both need to undergo a compatibility test, for which they will have to take a blood test and undergo other related studies, which will already be prescribed by the attending physician.
But even if, as a result of all the research and testing carried out, incompatibility on any factor is discovered, do not become depressed or despair. Remember: modern medicine is in constant development, in constant discoveries, which always gives potential mothers a great chance to get pregnant and give birth to a healthy baby. And we should not forget that the most important factor for conceiving a child is not so much the compatibility of the spouses as the presence of sincere feelings between them. The birth of a long-awaited baby will overcome all obstacles!
Especially for Anna Zhirko
When planning a child, a woman should consult a gynecologist, undergo a full examination of the body and preventive vaccination to avoid problems during pregnancy. If the third negative and third positive blood groups predominate among sexual partners and future parents, a Rh conflict, which is dangerous for the mother and intrauterine development of the fetus, cannot be ruled out.
3 positive and 3 negative blood groups in parents mean a high risk of developing Rh conflict, which in most cases leads to unwanted termination of pregnancy. In addition, doctors suspect extensive pathologies at the intrauterine level, fetal stillbirth or premature birth. However, with a competent approach to the problem, such consequences for children’s health can be avoided; the main thing is to regularly see a specialist and undergo scheduled and unscheduled screenings in a timely manner.
The appearance of a child with the third blood group
If
3 predominates among future parents
negative and 3 positive, this does not mean at all that the baby
will also be born with the third blood group. To get this result,
The following combinations are required:
Fourth
and third blood group;
Third
(fourth) and first blood group;
Third
(fourth) and second blood group.
The “blood affiliation” of a child can be determined based on the results of laboratory tests of both
parents, however, the composition of the blood, as is known, is updated several more times in
human life.
Some
When planning a pregnancy, women ask their personal gynecologist the same question:
"If I have 3 negative,
My husband has 3 positive, is there any reason for concern?" Actually
In fact, there are significant concerns, since when carrying a fetus in such a combination in
dangerous antibodies can form in a woman’s blood; however, this only happens if the fetus is from
the father will inherit a positive Rh factor. The situation is uncommon, but also
present in extensive obstetric practice.
However
such a medical verdict does not mean at all that a progressing pregnancy
is doomed to be interrupted, since modern medicine knows highly effective methods such as
help a pregnant woman carry and give birth to a completely healthy child.
Of course, you will have to remain under close supervision of a specialist for the entire 9 months, but, as shows
practice, the results are really worth it.
If
If the expectant mother has a positive Rh factor, and the father is negative, then
there is no problem as such, but a Rh conflict during pregnancy
you don't have to worry about it. When such a pathological process does occur,
the expectant mother must understand that in her case there is no question of abortion
Maybe; Otherwise, getting pregnant again will be very difficult.
If

Useful information about donation
Today, the third blood group is considered rare, and its owners are donors who are very valuable for medicine. They can assist patients with blood groups 3 and 4 in accordance with the predominant Rh factor. If they themselves need blood, donors with group 1 or 3 of the corresponding Rh factor will come to the rescue.
Before donating blood as a donor, the doctor studies the clinical picture in detail and asks about the presence of diseases such as a form of hepatitis, HIV and others. If there are no such diagnoses and have not been, then the blood provided is suitable for people in need. Afterwards, the existing blood type is determined using special tests, and the diagnosis takes only a couple of minutes.
Pregnancy with negative Rh factor
If a woman with a third blood group with a negative Rh factor carries her first pregnancy, then complications are possible throughout the entire period. The fact is that the formed antibodies gradually accumulate, and in the third trimester they remind themselves of pathological childbirth and intrauterine pathologies.
It is very important that the first pregnancy is not terminated, since the fetus is surgically removed from the womb, but the formed antibodies in the blood retain their previous concentration. This means that a subsequent pregnancy may not occur, because dangerous enzymes suppress ovulation or contribute to the rejection of a fertilized egg.
Blood is the main carrier of information about the human body. Today, there are 4 groups and 2 types of this substance. Each blood group has its own characteristics. In addition, it is this component that helps to develop certain character traits and preferences in a person. Today we have to understand what 2 positive blood group is. Characteristics, compatibility and nutritional features are topics that will be covered further. All the information offered to your attention may pleasantly surprise you. Few people even think about how a person’s blood affects his life.
General information
Blood is the most informative unit of the human body. Her group is a genetic trait that does not change throughout life. No matter the circumstances, the blood always remains the same. It is laid in a person in the womb, and then accompanies the citizen throughout his life.
Today in science there are, as already mentioned, 4 blood groups: first, second, third and fourth. Blood group 2, according to statistics, is the most common. About 1/3 of the entire population of the Earth are its owners. This blood is often called the blood of landowners. This group is considered the oldest, it existed even before the mixing of human races.
As already mentioned, there are 2 types of blood - positive or negative. The most common option is the first. 2 positive blood group, the characteristics of which will be presented below, is present in a larger number of the population around the world.
It is noted that this type of blood appeared only after the 1st. Some suggest that this is related to the development of humanity. Primitive people were able to eat carbohydrates. They began to engage in gathering and farming. During this, the 2nd blood group was formed.
If you briefly describe people with this “substance”, you will notice that they are sociable and flexible. In addition, they tend to idealize the world. People with blood group 2 are excellent organizers.
About genetics
Now a little about the genetic properties of the studied information unit of the human body. The second blood group is designated as A (II). This is exactly the interpretation proposed in the AB0 system. The only thing that distinguishes this blood group is the presence of A-antigens in red blood cells.
In order for the properties of an information unit to be inherited by a child, one of the parents must have a similar antigen. Accordingly, positive blood group 2, the characteristics of which are given below (and negative ones too) can be combined with other blood. There are 3 different combinations in total.
It is necessary to understand genetic characteristics at the stage of planning a child. The thing is that problems with conception often occur due to the characteristics of the parents’ blood. In addition, complicated pregnancy and health problems in the child can also be associated with blood. Especially with the Rh factor.
If the baby’s parents have the same antigens, then the child will definitely inherit them. Otherwise, the strongest component will “win.” It can come from either the mother or the father.
Blood type of parents and children
In order to answer this question correctly, it is necessary to thoroughly study genetics. But for ordinary people, scientists have come up with various calculators and compatibility tables.
If the parents have blood type 2+, most likely the child will also have A (II). But the Rh factor can be negative. In addition, it is possible that the baby will have blood type 1. This is normal, although very rare. It occurs in approximately 6% of cases.
To be able to give birth to a baby with blood group 2, the following combinations of this substance must be present in the parents:
- 2nd and 4th;
- second or fourth + 1st (without antigen);
- fourth or second + 3rd.
Parents with blood types 1 and 3 will never produce a child with blood types 2. All this is due to the lack of antigens. Such a combination is a reason for a medical examination. The point is that if the mother and father have blood types 1 and 3, they cannot be the parents of a baby with group 2.
Blood compatibility during transfusion
But this is not all the interesting and important facts. 2 positive blood group, the characteristics of which will be fully studied further, has its own characteristics of compatibility during transfusion. It is at this moment that the Rh factor must be taken into account. Any blood transfusion center clarifies the donor’s blood type before starting the process. Otherwise, you may lose the patient.
The 2nd positive blood group does not have very extensive compatibility. This means that not everyone can transfuse it. Such people can act as donors for patients with 2nd or 4th positive blood groups. As a recipient, citizens with group 2+ can receive blood groups 1 and 2. In this case, the Rh factor can be anything - both positive and negative.
A+ does not combine with other blood in any way. As already mentioned, this blood group has very limited compatibility. This fact should be taken into account by all healthcare professionals.
Blood and character
2 positive blood group, the characteristics of which are presented to our attention, endows its carriers with certain character traits. Some believe that it is blood that influences human behavior.
People with positive blood group 2 have a decent attitude towards loved ones, friends and relatives, a tendency to work in groups, sympathy and care for those who are dear to them.
Such people are excellent leaders. Only in reality they usually give primacy to others. People with A+ dream of recognition and leadership, but carefully hide it. Such behavior often leads to internal feelings and stress.
About choosing a profession
Who is the best person to work for carriers of the 2nd positive blood group? To do this, you need to pay attention to the characteristics of a person’s character. Nature has come up with many professions for such people.
All the previously mentioned features should not be overlooked. People with blood type 2 (positive) are excellent teachers, doctors, and social workers. They work wonderfully with personnel and can help in election campaigns. It is in these areas that it is recommended to choose a profession for such citizens.
Health risks
But this is not all the interesting and important facts. The compatibility of blood groups 1 and 2 (positive) is now clear. Moreover, it is now clear what character traits the carriers of this informational genetic unit are endowed with. An extremely important point is the health status of a person with A+.
Some believe that blood type has a serious impact on the human body. In addition to character traits, people acquire certain vulnerabilities. For example, such citizens have the following characteristics:
- low immunity that occurs due to infections, stress, poor diet or physical activity;
- increased blood clotting;
- tendency to thrombosis;
- impaired absorption of proteins and fats;
- low stomach acidity.
Accordingly, 2 positive blood group, the compatibility of which we already know, gives a person the following vulnerabilities:
- diseases of the cardiovascular system;
- allergic reactions;
- increased susceptibility to foodborne infections;
- predisposition to gastritis, pancreatitis;
- risks of developing malignant tumors.
Perhaps these are all the health features that need to be remembered. What else important can you learn about people with positive blood group 2?
About nutrition
For example, it is recommended to pay special attention to nutrition. For the category of people under study, it implies a gentle regime. How should nutrition be organized according to blood type? 2 positive (the table of permitted products will be presented below) blood is not only a tendency to leadership, but also an organization for the prevention of obesity.
Accordingly, you need to eat right. It is noted that many people with A+ are inclined towards vegetarianism. Their main diet is vegetables and fruits. Vegetable oils are also beneficial. For example, flaxseed or olive. Cereals allowed for consumption are buckwheat, rice, millet, barley. Don't forget about beans and lentils either. A+ cereals are a great menu item.
Among vegetables and fruits, preference should be given to those that enhance the formation of gastric juice. For example: cherries, oranges, apples, pineapples, beets, carrots, bell peppers, cucumbers. Spices are not recommended. You can leave only the mustard.
Seafood and delicacies can be consumed, but in limited quantities. Garlic, ginger, soy sauce and drinks with malt are also not recommended. Despite this, they are not prohibited. Soy substitutes are allowed to be used without restrictions.
Results and conclusions
Now it is clear what Rh positive blood is in the second group. In addition, it is now clear what character traits people - carriers of this informational genetic unit - possess. In fact, everything is much simpler than it seems.
From all of the above, we can conclude that the 2nd positive blood group makes a person a person with leadership qualities, empathy, a tendency to stress and reduced immunity. The diet of such people should be balanced.
Any blood transfusion center will advise that problems may arise with the transfusion. After all, the 2nd positive blood does not combine well with the rest of the genetic information units. All people will have to remember this.
