What is the importance of blood type for blood transfusion?

The importance of the blood type for blood transfusion lies in the risk of cluster of donor blood in the recipient's bloodstream, a process called agglutination. Cruising red blood cells can cause serious toxic reactions, often times to death in a person who receives a transfusion. Agglutination is a reaction caused by the immune system that occurs in the presence of antibodies that form against the red blood cells of the donor. In order to alleviate the agglutination, the types of blood of the donor must be compatible. Blood types

are determined by the presence of different protein molecules, especially antigens and antibodies. Antibodies are found in blood plasma, a liquid substrate for red blood cells, components transmitting oxygen blood. Antigens are found on the surface of any red blood cell. Each individual has different combinations of these antigens and antibodies. Which combination is present to a large extent depends on inheritance. For this reasson, many blood transfusions take place between donor and siblings, parents or otherme close to family members.

Blood type for blood transfusion is categorized by ABO blood type. In this system, the blood is classified into four groups: A, B, AB and O. Individuals who have a blood type A have specific antigens on the surface of their red blood cells A and also have antibodies specific to B in the blood. The same formula applies to individuals with blood type B; Have B specific antigens specific to B and A-special antibodies in their plasma. Individuals with blood type AB have antigens A and B on their red blood cells and plasma no antibodies, while individuals about blood type have no antigens but have antibodies in plasma A and B.

Blood type for blood transfusion is also important in regurds to another specific antigen, RH, which also adheres to the surface of red blood cells. This antigen is referred to as a factor. An individual that has an RH antigen is referred to as JAKO RH positive (rh+) and those who are not referred to as RH negative (rh-). RH Blood type for blood transfusion is recorded because a person with RH-curve does not have the corresponding RH antibodies in the plasma. If this person should receive blood from the donor RH+, a toxic reaction may occur.
