The third blood group is considered rare - it is found in only 15% of people inhabiting the Earth. According to some reports, we owe its appearance to the nomadic Mongoloids. The age of the group is more than 17 thousand years. The third negative is, accordingly, even less common. It is more common among people living in Asian countries, the Middle East, and Africa. Interestingly, some researchers say that it determines a person’s character. So let's get to know the third negative category in detail!
General information
Blood is a biological fluid that circulates throughout the body of every person in a volume of 5-6 liters (approximately 7% of body weight). Researcher K. Landsteiner discovered four of its categories:
- The first one is O.
- The second is A.
- Third - V.
- The fourth is AB.
The most common option is the first, the rarest is the fourth. The third negative will be in honorable second place in terms of non-prevalence.
The third group is compatibility during donation
A person with group 3 will not be a universal recipient. In other words, his blood for transfusion is not suitable for everyone. Blood of the first group is universal. But for those with the 4th category, blood of all groups is suitable - 1, 2, 3 and 4.
Here's what concerns the third blood category in this vein:
- A person with group 3 can become a donor for people with blood categories 3 and 4.
- It is permissible for a person with blood group 3 to receive blood transfusions of the first and third categories.
- The 3rd positive and the 3rd negative are incompatible! Rejection can even be fatal for the patient.
If it is not possible to transfuse suitable blood to a person in need, then specialists use serum or blood substitutes (“artificial blood”) - special sterile liquids that can replace it itself, as well as plasma. Such compositions are not a complete alternative, but are capable of supporting human life.
How does a child turn out with the third group?
Group B(III) of the antigen structures has only B. This means that one of the parents must have this antigen. This situation is possible if both parents have 3-4 or mixed groups:
- third + fourth;
- third or fourth + first (without antigens);
- third or fourth + second.
One thing is clear: a baby with the third group cannot appear from parents with the first and second, since they both do not have the B-antigen. This rule is used to establish paternity and determine identity in forensic practice.
Rh factor value
So why is the third negative incompatible with the third positive? It's all about the Rh factor (+/-). It was discovered by scientists A. Wiener and K. Landsteiner in 1940.
The Rh factor is a special antigen that is found on the surface of erythrocytes - red blood cells. Interestingly, it does not change throughout a person’s life, and is also transmitted from parent to child.
According to statistics, 85% of the population of our planet have a positive Rh factor and only the remaining 15% are negative (that’s why there are so few people with the third negative group). The meaning of the difference is as follows:
- Blood of the same group, but different Rhesus is incompatible! Transfusion can have consequences for the patient, including death.
- It is important to note that different rhesus diseases with the mother threaten the child with death in the womb. For example, if a woman has third negative blood, and the baby has third positive blood, then the embryo is in danger.
Why is that? A woman’s body perceives a child with a different Rh factor as a foreign body, virus or infection. The mother's immune cells begin a fight against the fetus, which ends with placental abruption or spontaneous abortion. This likelihood is most common for women with strong immunity.
Future parents need to remember that the danger is observed only during a problematic pregnancy! During normal gestation, the blood of the mother and child does not mix, which is why there is no threat.
Planning pregnancy and 3 negative blood group
In women, the Rh characteristic affects the course of pregnancy and its outcome in the case when the girl is negative, and the guy who will become the father is positive. In this case, you need to see a doctor for advice.
Usually, the first pregnancy with such indicators passes without disturbances and risks for the expectant mother and child. Future pregnancies will require close monitoring by a gynecologist.
Rh conflict tends to occur in the last period of pregnancy. To avoid the development of such a scenario, doctors refer the young couple to undergo an Rh test. Based on the results obtained, the doctor will be able to draw conclusions.
If a woman who is Rh negative carries a child who is Rh positive, doctors will offer an anti-Rh globulin vaccine. A timely visit to the clinic for specialized help will give confidence in the successful development of pregnancy without subsequent complications.
Compatibility of father and mother
We now know that the discrepancy between the blood characteristics of a pregnant woman and the embryo has serious consequences. They are especially severe in the case when the child has a third negative blood group, and the mother has the first or second. But let us note once again that the danger is real only for problematic pregnancy.
But now let’s move on to the Rh harmony of father and mother. Let's look at the compatibility of parents who have blood group 3:
- The third is negative in a woman. A suitable father is with blood types 1 and 3.
- The third is negative in a man. A suitable mother is with the 3rd and 4th blood groups.
What threatens the incompatibility of mother and father by Rhesus?
The danger of Rh-conflict between parents
Everything is simple here - a mismatch in the Rhesus of the parents causes a mismatch in the Rhesus of the mother and the embryo. After all, as you remember, it is inherited.
Rhesus conflict is dangerous for mother and baby in the following ways:
- Stillbirth of a child.
- Miscarriage is a spontaneous abortion.
- Fading pregnancy is stopping the development of the embryo in the mother's womb.
- The appearance of pathologies in the fetus that are incompatible with life.
It is important to note that open Rh conflict will manifest itself only in the last months of pregnancy. Before this, it can affect the abnormal formation of the internal organs of the embryo - mutational changes are possible.
Doctors also note the fact that when parents have a Rh conflict, the first child is born without problems in most cases. And the second baby will be in danger. Therefore, if the first pregnancy went perfectly, a woman should still carefully prepare herself for the second.
However, Rh mismatch is not a 100% predictor of dire consequences. Today, future parents can undergo a course of special treatment, which significantly increases the chances of having a healthy and healthy baby.
Even if there is Rh harmony between the father and mother, planning a child still needs to be approached with all responsibility - use tests to determine ovulation, regularly visit a specialist and follow his recommendations, follow a diet, a healthy lifestyle, etc.
Physical characteristics of the group
It is noted that people with the third blood category for the most part have strong immunity. However, for this group there are a number of diseases to which, according to statistics, they are most susceptible:
- Inflammation of the lungs - pneumonia.
- Apathy, depression.
- Sclerosis.
- A number of joint diseases.
- Osteochonrosis.
- Autoimmune diseases.
- In women, complications develop after childbirth.
You should not assume that every person with blood type 3 must necessarily get sick from this entire list. This is just a reason to remember your exposure - lead a healthy lifestyle, monitor your emotional state, eat healthy foods
Special tips for using medicinal plants
According to the theory of blood groups, raspberries, rose hips, sage, mint, ginger, and parsley have a beneficial effect on people with the third group.
Birch buds, hawthorn, St. John's wort, valerian, burdock, oak bark, chamomile, yarrow, echinacea, and strawberries are considered moderately harmful.
It is strictly not recommended to use decoctions and tinctures of aloe, linden and coltsfoot leaves, clover flowers, and hops.
Suggestions and restrictions must be used wisely to develop an individual menu for the purpose of losing weight. The following sports are recommended: cycling, swimming, jogging.
Knowing the benefits of your blood type will require some effort in their practical application. Let the conclusions of American researchers serve as consolation: about 40% of US millionaires have group B (III).
Psychological characteristics of the group
Surprisingly, the ratio of antigens (A and B) affects not only the physical characteristics of a person, but also his psychological portrait! In this vein, the third negative blood group in women and men is manifested by the following personal characteristics:
- High level of creativity.
- Cunning and wisdom.
- Manifestation of some selfishness in behavior.
- Excellent oratorical qualities - emotional speech, a penchant for diplomacy. In other words, these are people who are capable of leading.
- Frequent and rapid mood swings, some nervousness.
- Sometimes there is excessive emotionality.
- Carriers of the 3rd blood group are most often surgeons, lawyers, accountants, and representatives of other serious professions.
How to determine the third negative?
The determination method is universal for all groups - this is giving a blood sample for analysis. The collection is carried out from a vein. The study can be carried out by almost any clinic. This procedure is worth going through not only out of curiosity. You will receive vital information for donation and family planning. The event always precedes blood transfusion, tissue and organ transplantation.
Preparing for the analysis is simple:
- It is better to donate blood in the morning and on an empty stomach (at least 4 hours after the last snack).
- After completing the course of drug treatment, at least 2 weeks should pass.
- If it is not possible to stop taking your medication, be sure to tell your specialist what you are taking.
- The day before the procedure, avoid alcohol, salty, fatty, and spicy foods.
- Before taking blood, protect yourself from physical and emotional stress.
The third negative blood category is one of the rarest. However, for its carriers the fact will not be a problem. On the contrary, this is a feature of the psychological portrait of the individual, which, according to scientists, is also influenced by antigens. It is important to know this blood group for planning pregnancy, donating blood, tissues, and organs.
