What is the Rh factor?

What is the Rhesus factor of the blood, the average person imagines very vaguely, although he knows the term for sure. In medical terms, he describes very incomprehensibly.In this article we will try to tell about it as easy as possible.

The concept of Rh factor

The blood of any living creature possessing it contains in its composition red blood cells, which are responsible for the movement of oxygen through all the cells of the body. In the overwhelming majority of people (about 85%), red blood cells are coated with a protein called an antigen. That's what the Rh factor is! Those individuals that have such an antigen are considered Rh-positive. Who he is absent - Rh-negative.

Why do you need to know the Rh factor

In everyday life it does not matter at all whether it is positive or negative. Neither health nor the propensity for any specific diseases, it does not affect. Rh factor is necessarily taken into account in two cases:

  1. if necessary, blood transfusions. It is clear that they pour the “group into the group”, no one will add to your blood of the 1st group donor 4th (and only in extreme cases, if not necessary, can the “older” transfuse into the “younger”).But under no circumstances can you mix the blood of different Rh factors of even one group! There is a Rhesus conflict, and instead of helping a person, you can kill;
  2. when creating a family, if you intend to have children in the future. If a potential mother has a Rh negative, and a father has a positive one, and if the child “goes” to the father, the woman has very low chances to bear and give birth to the child - the same Rh-conflict appears.
