Overview. The ABO system is regarded as the most important blood-group system in transfusion medicine because of severe hemolytic transfusion reactions and, to a lesser degree, hemolytic disease of the newborn. ABO grouping is a test performed to determine an individual's blood type. It is based on the premise that individuals have antigens on ...

ABO blood group antigens present on red blood cells and IgM antibodies present in the serum. The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes. For human blood transfusions, it is the most important of the 44 different blood type (or group) classification systems currently recognized by the International Society of Blood ...

Latest Modified. ABO grouping is a test performed to determine an individual's blood type. It is based on the premise that individuals have antigens on their red blood cells (RBCs) that correspond to the four main blood groups: A, B, O, and AB.

The basis of ABO grouping is of two antigens- Antigen A and Antigen B. The ABO grouping system is classified into four types based on the presence or absence of antigens on the red blood cells surface and plasma antibodies. Group A - contains antigen A and antibody B. Group B -contains antigen B and antibody A.

Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also known as a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids ...

ABO Blood Group System. ABO blood grouping is based on the principle of an agglutination reaction. It is the popular method for blood group identification to determine the presence and absence of cellular antigens and their relative antibodies in the blood. In blood typing, the detection of antigen in the donor's RBCs is called forward typing.

There are four major categories within the ABO group: A, B, O, and AB. Within these groups, there are a further eight blood types. Every 2 seconds , a person in the United States needs blood.

ABO Grouping. ABO Blood Groups. ABO blood groups are assigned based on the major blood group antigens present on a patient's red cell. Patients can either have A, B, A and B or no antigens (blood group O). Patients have naturally-occuring antibodies to the antigens they lack; i.e., blood group A patients have anti-B antibodies, blood group B ...
