In some countries, especially Japan, people are sure that you can recognize the character by blood type. The blood type and Rh factor of a person are indicated in the resume during a job search. Some Japanese companies are taking on leadership positions, given these nuances.
Blood type is a combination of red blood cell antigens, which is determined by human genetics. Rhesus factor called a special protein on the membrane of red blood cells. The presence of this protein indicates a positive Rh factor, which is possessed by 85% of the population; absence is negative.
The most common group is the first. It was determined in 40-50% of people. The fact is that, as many scientists believe, this is the oldest blood group that all people on the globe had a hundred thousand years ago.
30-40% of people have the second group. 10-20% have a third. And only 5% of people around the world can boast of the fourth, rarest blood type. It arose as a result of mixing the second and third literally a thousand years ago.
However, the determination of the blood type and Rh factor is necessary not only to get acquainted with the nature of the person. Blood transfusion is impossible without these data. After receiving serious injuries, during many dangerous illnesses a person is injected with suitable blood. In any hospital, tests will be performed to determine this indicator. However, in an emergency there is no time for such procedures. Therefore, each person should know their group and Rh factor.
In a medical laboratory, specialists take a drop of a patient’s blood from a finger for analysis. The group is determined using standard isohemagglutinating serums. Special serums are applied to white plates with a special surface, a small amount of blood is placed on each plate. As a result, the specialist receives a combination of positive and negative reactions, which allows him to determine the group affiliation of the patient. This procedure takes several minutes, the patient experiences minimal pain when the doctor pierces the skin of a finger to take blood.
How to determine the blood group without going to a medical clinic?
First, check your passport. Some people have a special stamp on their passport that shows their blood type and Rh factor.
Secondly, examine your medical record. Often it contains all the necessary information. Group signs of blood can have a value of 00 (denoting the first group), 0A (second), 0B (third) and AB (fourth).
Third, find out the blood types of your parents. If they match, you probably inherited the same group.
However, if you have not found such instructions anywhere, contact your health care provider for testing. These tips on how to determine the blood group can only be applied in situations where you have forgotten the result of such studies. There are no other exact ways to identify your group. Only a specialist can examine your blood. Modern medicine makes it incredibly easy and fast with the latest inventions.
Do not delay these procedures. Since you can determine the blood group without significant financial costs, go to the clinic in the near future. You should know not only your own blood group and Rh factor, but also the same information about your loved ones. Remember, with serious injuries, a person often dies from blood loss, and only knowledge of the necessary information will allow doctors to immediately receive a transfusion. It’s useful to keep an extract from the clinic confirming your group. In this case, doctors will be able to help you, even if you lose consciousness.
An emergency can happen to anyone at any time - no one is safe from this. But it is in our power to influence its outcome. To do this, you do not need to argue how to determine the blood group without analysis. You need to find the blood type marks in your passport or on a medical card, and if they are absent, turn to specialists.
