Blood compatibility refers to the compatibility of blood types between individuals, particularly in the context of blood transfusions. There are four main blood types (A, B, AB, and O) and each type can be either Rh positive or Rh negative. It is important to match blood types between donors and recipients to prevent adverse reactions, such as hemolysis (destruction of red blood cells) or an immune response. Blood compatibility testing is typically done before a blood transfusion to ensure that the donor blood is compatible with the recipient's blood type.

Blood compatibility refers to the ability of two individuals' blood types to mix without causing an adverse reaction. It is primarily determined by the presence or absence of specific proteins, known as antigens, on the surface of red blood cells. The most important blood group antigens are the A and B antigens, which give rise to the four main blood types: A, B, AB, and O.
When blood from an incompatible donor is transfused into a recipient, the recipient's immune system may recognize the foreign antigens on the donor's red blood cells as a threat and produce antibodies against them. These antibodies bind to the antigens, causing the red blood cells to clump together and break down, a process known as agglutination. This can lead to life-threatening complications such as hemolytic transfusion reactions, where the recipient's red blood cells are destroyed, and disseminated intravascular coagulation (DIC), where widespread blood clotting occurs.
To ensure safe blood transfusions, blood compatibility testing is performed before any transfusion. This involves determining the blood types of both the donor and the recipient and checking for the presence of any antibodies that could cause an adverse reaction. Blood transfusions are only performed when the donor's blood is compatible with the recipient's blood, meaning that the recipient does not have antibodies against the donor's antigens.
The concept of blood compatibility also extends beyond blood transfusions. In the context of organ transplantation, blood compatibility between the donor and the recipient is important to prevent rejection of the transplanted organ. Similarly, in pregnancy, blood compatibility between the mother and the fetus is essential to prevent complications such as hemolytic disease of the newborn (HDN), where maternal antibodies cross the placenta and attack fetal red blood cells.
