How to identify a blood group

In some countries, especially in Japan, people are sure that by the blood group one can learn the nature. The blood group and the Rh factor of a person are indicated in the resume during the job search. Some Japanese companies are taking on leadership positions, given these nuances.

The blood group is a combination of erythrocyte antigens, which is determined by human genetics. Rhesus factor is called a special protein on the erythrocyte membrane. The presence of this protein indicates a positive Rh factor, which is 85% of the population; Absence - about negative.

The most common group is the first one. It was determined in 40-50% of people. The fact is that this, according to many scientists, is the oldest blood group that all the people of the globe had a hundred thousand years ago.

At 30-40% of people - the second group. At 10-20% - the third. And only 5% of the people around the world can boast of the fourth, the rarest blood type. It arose as a result of the confusion of the second and third literally a thousand years ago.

As a result, the expert receives a combination of positive and negative reactions, which allows him to determine the group membership of the patient. This procedure takes several minutes, the patient experiences minimal pain when the doctor pierces the skin of the finger to take blood.
