Blood Rh-Positive

Rh Positive Blood: Meaning and Features

Rh positive blood (Rh+) refers to a category of blood in which the red blood cells contain the Rh factor. Rh factor is a protein found on the surface of red blood cells. The discovery and study of the Rh factor was of great importance in the field of medicine and transfusiology.

The history of the discovery of the Rh factor is associated with the work of the American immunologist Karl Landsteiner and his colleagues. In the 1940s, they discovered the presence of an antigen that caused antibodies in the blood of some people. This antigen was named "Rhesus" in honor of the Rhesus macaque monkey on which the first experiments were carried out. Thus, people with the presence of the Rh factor in their blood were called “Rh-positive”, and those who did not have it were called “Rh-negative”.

A feature of Rh-positive blood is the presence of the Rh factor, which determines its compatibility with other blood. If a person with Rh-positive blood receives a transfusion from an Rh-negative donor, their immune system may begin to produce antibodies to the Rh factor. This may lead to allergic reactions or problems with subsequent blood transfusions. Therefore, it is important to consider blood compatibility when performing transfusions.

However, Rh-positive blood does not have any negative consequences for the person who is its carrier. The Rh factor does not affect the overall health and functioning of the body. It is also not associated with determining blood type, which is determined by the presence of A and B antigens on red blood cells.

Knowledge of blood groups and the Rh factor is of great importance in medicine. This helps in conducting safe blood transfusions, especially in emergency situations when it is necessary to quickly provide the patient with the necessary blood components. Also, knowledge of blood groups and the Rh factor is important when planning pregnancy in order to avoid problems associated with incompatibility of the blood of the mother and fetus.

In conclusion, Rh positive blood is one of the categories of blood characterized by the presence of the Rh factor on the red blood cells. Blood compatibility plays an important role in medicine, and knowledge of blood groups and the Rh factor helps ensure safe blood transfusions and prevent possible complications.

Rh factor and positive blood **Rh negative blood** is essentially not an error in determining the child’s blood, but a congenital anomaly: the baby lacks one of two types of special protein - the Rhesus antigen or does not have it at all. This phenomenon is widespread among people in the world, more than 40%, and is most often found among the Chinese, blacks, Malays and people from Africa.

Only about 7% of the world's population has negative Rh. In our country, negative Rh factor is common among people of Tatar nationality and people from Central Asia. Can be found in all Caucasian peoples. But among those who live in the Vologda, Vladimir and Ivanovo regions, almost every second person has a negative result. The most carriers of this antigen are in the Caucasus and Crimea. Negative Rh is very rare among Estonians of Finno-Ugric nationality, especially among northern Estonian residents.
