Do you know your blood type? No, but in vain. This indicator should be known to every person from a young age, as their last name, first name and home address. You ask, why? Well, in life everything happens. For example, an accident on the road, a person lost a lot of blood, doctors "ambulance" ask who has such a blood type, help. If you are nearby, knowing your group, do not really respond? And if you do not know, you will suffer from impotence. Or one of the relatives will have an operation, and a transfusion is required, and you do not know whether you are suitable as a donor or not. But how many still, what situations happen. So the knowledge is very important. And, how and where you can find out or determine your blood type, we'll talk about this article.
What does the blood consist of?
But before you start to understand the process of determining the blood type and your Rh factor, let's talk about what it consists of. So, the constituent parts of the blood are liquid plasma and thick uniform elements. Plasma - this is the component of blood, which makes it liquid and allows spreading throughout our body. By the way, normally blood is thicker than water only four times, and in people prone to atherosclerosis and thrombophlebitis, at ten. Formed elements include red blood cells - erythrocytes, white blood cells - leukocytes and wound closers - platelets. The blood group and Rh factor are determined by the first. It is known that on the surface of erythrocytes there are antigens called aglutinogens, which are divided into two groups "A" and "B". And the serum contains antibodies called agglutinins. They, too, are divided into two groups, "alpha" and "beta." In the laboratory mixing of different samples with each other on their reaction and it turns out which group belongs to one or another of them. This definition of the blood group is called the ABO system study. It is now known that there are more than 1.5 million different groups based on the individuality of each person. However, the conventional classification includes four groups, within each of which there can be either a positive or negative Rh factor. And the first, as a rule, dominates. If, for example, one of the parents has an I group with the Rh factor "+" and the other has the same, but with the Rh factor "-", then the child is likely to have a positive Rh factor. This is another reason why you need to know your indicators. Well, now let's go find out how and where you can find out or determine your blood type and Rh factor.
Where and how to determine the blood group?
Of course, in the laboratory, more, unfortunately, nothing. Some special appointments are not necessary for this. Just come to the local therapist and explain to him your desire. The doctor is only happy to go to your meeting, because people who care about their health, not really in fact and a lot. Having received a referral, you in the morning on an empty stomach hand over the usual analysis of blood from a finger or from a vein. Then the blood is sent to the laboratory, where one very simple manipulation will be performed on it.
A simple immune-haematological reaction
Here's how you can determine which blood type you have, using a simple study. The doctor-lab assistant on a flat plate with a wax pencil makes eight notes on the number of groups and Rh factors in each of them. Further, according to these notes, he places a serum near each of them, which is slightly added by blood from the analysis of the patient. As soon as the group and the Rh factor of the patient and the reference serum coincide, agglutination will occur. That is, antigen from the serum will combine with the antibody from the patient's blood, and sand will precipitate. It is seen that this reaction will be five minutes after the experiment. For accuracy, the result in the isoserological laboratory is confirmed by a cross reaction. It serves to recheck and clarify the Rhesus factor. To do this, take the standards of groups I "a" and II "b" and add blood to them from the analysis of the patient. After five minutes, the reaction will show what kind of Rh factor you have.
Here's how you can find out your group and the Rh factor of blood. The information about these data is usually placed on the passport, since it is the most reliable and the most important document for a person. About blood groups for now, take care and be well.
