Separation of blood into four different groups was not so long ago.Approximately in 1901, Karl Landsteiner, who later became a Nobel Prize winner, was able to identify the first three - A, B and O, which have become fundamental to the whole medicine.The fourth group was discovered only later on the grounds that it is fairly rare in Europeans.And in 1928 it was approved the official designation of all four groups - O (I), A (II), As (III) and AB (IV).And, while today there are more than 250 species of blood, it is important to know these four, as they are - the most important and serious.
Why do we need to be informed about how to know your blood type?There are several reasons.The most serious - in the case of an accident you may need a blood transfusion.The fact that there is mutual compatibility groups.For example, a person with blood 2 (A) may be a donor only to recipients (who need blood transfusions) 2 (A) and 4 (AB).Therefore, people who are in a combat zone or engaged in work related to the risk of their lives, give special medals or badges showing their blood group with Rh factor.This is to ensure that health professionals know exactly the data in any situation.Indeed, in such cases, medical care is often required immediately, and the patient may be unconscious.Also, information about blood type is sometimes referred to in the passport.This is more of a precaution, but in case of accident can greatly help physicians.
therefore about where and how to find out your blood group, care must be taken as soon as possible.
This factor is transmitted to us by right of succession, and does not change throughout life, so take the time to have its definition only once.And then, what group would be in a child depends on the parents.If you are interested, how do you know the blood group home, albeit roughly, that detailed examples of what combinations give a particular result.It does not matter, my mother or my father a certain type.
combination of the first two groups will result in the same with absolute certainty.
first and second - first or second.
first and the third - the first or third.
first and fourth - third or second.
two second - first or second.
third and second - second, first, third or fourth.
second and fourth - one of them, as well as the third.
When a combination of two thirds of the group, the child will be the third or first.
third and fourth - the second, third or fourth.
If both parents have the fourth, then the baby will receive the same or third, or second.
Here's how to know your blood group in the table.As you can see, the results are quite different, even if the parents, it is the same.According to statistics, the majority of the world's population has the second or the first group, and the rarest - the fourth.
There is such a thing as the Rh factor.It is marked with the Rh-plus (if positive) and minus (if negative).However, it looks like this: 2 (A) Rh- is the second group of blood to Rh-negative.It is also important, because the blood of people with different indices incompatible.It accounted for transfusion or surgical intervention.Also, the Rh factor affects the course of pregnancy in a negative value of a future mother.If the baby it is positive, it can cause some problems with the pregnancy and childbirth.But you should not be afraid of this, because modern medicine has learned to correct this situation, and in most cases the pregnancy ends happily.
Until then, how do you know your blood type exactly 100%, you will need to contact your doctor and get tested.This is done in any clinic and does not take much time.An analysis of a group of doctors perform blood in case you for some reason need serious medical help, but this factor is not reflected in your medical record.
Currently, there are even certain diet for holders of different groups, and it is believed that the predisposition to disease is often associated with this factor.
