Study: which blood group is considered the best: positive and negative sides

Seven to eight percent of the body's weight is taken up by blood - the most important participant in life, performing a huge number of functions. The blood of all people is divided into groups, today there are four. The Rh factor is separately taken into account: it is either positive or negative. One knows the blood data from birth, and others receive this information at some point in their lives. But what is the difference between different types, and what is the best blood group? Each variety has its own shortcomings and advantages, which are worth knowing about.

How to understand which blood group is the best?

According to medical statistics, the most common group is the first - 50%, and the second - 40% of all people. This means that with blood transfusion problems with donor material will not arise. The third type in 8% of people and only 2% - the fourth. It is worth noting that people in any part of the world are dominated by a positive Rh factor-such blood four-fifths and only one part is negative - in their blood on the surface of cells there is no specific squirrel.

For convenience in medical practice, each group has an alphabetic and numerical designation:

  1. 0
  2. A
  3. AT
  4. AB
Type letter symbols

The Rh factor is indicated by the signs + (positive) and - (negative). Thus, in all, humans have eight kinds of blood.

It is worth noting that more often a child receives a parent group and a Rh factor.

Arguing about which group of blood is better, it is worth distinguishing two grounds:

  1. donation and transfusion;
  2. predisposition and resistance to diseases and pathological conditions.

In addition, we emphasize that the group and the Rh factor affect the conception of the child. The blood of parents should be approached to each other. Favorable situations:

  • If both partners have the same group, the Rh factor in the woman is positive;
  • At the man 0 group (the first);
  • The future mother has a fourth group.

Pregnancy proceeds with complications, there is a danger to the fetus if the woman has a negative Rh factor, and the future child has a positive Rh factor. In this case, a conflict arises and the chance of miscarriage increases, because the mother's organism perceives the fetus as an alien phenomenon.


Note! Awareness of the compatibility of blood in the planning of pregnancy helps to avoid a number of negative consequences.


Universality is the main thing?

Many believe that the best group is the first, since in this case the person is considered a universal donor. In this type, there are no antigens on the surface, as a consequence, the transfusion recipient does not produce antibodies against these cells. However, today blood 0 (I) for transfusion of steel is much less likely to reduce the risk of rejection. It is used only in case of acute necessity.

Donor Biomaterial

When transfusion is taken into account, the coincidence of both indicators is taken into account: both the group and the Rh factor. From this point of view, the best blood group is the first positive, since in all donor bases its number is leading. Starting from this point, it becomes possible to answer the question: which blood group is the worst? The fourth is negative, because it is always lacking.


Important! Everyone should know about their blood in case of emergency.


Highlighting strengths and weaknesses

Many people, when they come to the hospital, ask the doctors the question: which blood group is considered the best for health? At the same time, there is still no single answer, since each species has its own characteristic features.

The first type

There is an opinion that the best blood group is the first, because this type is the most ancient and universal. In emergency cases, it can be used for transfusion to others, so this blood is in demand at transfusion points.

  • Strengths: mental stability,
  • Negative moments: predisposition to diseases of the gastrointestinal tract, increased acidity of the stomach, risks of arterial hypertension. Carriers of this blood are susceptible to viral and infectious pathologies.

Patients with 0 (I) are prone to clotting disorders. If a patient with 0 group is transfused, only the same blood can be used.

Advantages and disadvantages

The second type

The next, slightly less common group is the second. A person with this type, in the opinion of cardiologists, should pay special attention to the state of the heart and blood vessels. According to medical data, people of this type often suffer from coronary artery disease, heart defects and have an increased risk of developing myocardial infarction.

  • Advantages: strong liver and organs of the genitourinary system;
  • Disadvantages: poor teeth, susceptibility to caries, heart disease, predisposition to gastritis, thyroid pathologies.

The third type

Carriers of the third group are characterized by poor mental health, among them neuroses and psychoses are common. The next weakness is the increased risk of developing infectious diseases of the urogenital system in women, which has negative consequences during pregnancy.

  • Positive features: resistance to cardiovascular diseases, in particular to myocardial infarction.
  • Negative: the risk of developing malignant colon tumors, Parkinson's disease, chronic slow current caries.

The fourth type

Another group of people distinguishes the fourth group as the best group, since it is considered the rarest with the negative Rh factor. Many scientists still consider it a mystery, because it arose as a result of a combination of extremely different types: A and B. The youngest and rare type of blood. Scientists say that people with such blood are flexible and strong immunity.

Uniqueness of this type lies in the fact that its appearance was influenced not by factors of the environment, but by mixed marriages, so AV (IV) can rightfully be considered biologically the most complicated.

  • Strengths: strong immune system, resistance to infections, pneumonia and bronchitis, strong and healthy teeth, strong genitourinary system;
  • Disadvantages: increased cholesterol, the risk of atherosclerosis, cardiovascular pathologies, obesity, increased coagulability, which leads to the formation of thrombi, thrombophlebitis.

Since the AV type is mixed, it is considered to be a universal recipient, which means that contact with other types does not call for rejection.

The listed positive and negative sides of each group do not guarantee that the bearer of a particular blood is the owner of precisely these characteristics.

As medical research shows, it is impossible to unequivocally answer the question which is the best blood group in a person. Because each species has its own shortcomings and advantages. For a deep immersion in this topic, we recommend that you familiarize yourself with this video:
