Blood groups, also called blood types, are the main varieties into which a person's blood may be classified, based on the presence or absence of certain antigens called agglutinogens on the surface of the red blood cells (erythrocytes). Significance ABO blood groups determine to whom one can donate blood from whom one can accept blood. His extensive research on serology based on simple but strong scientific reasoning led to identification of major blood groups such as O, A, and B types, compatibility testing, and subsequent transfusion practices.

ABO blood typing). What makes your blood different from someone else’s is your unique combination of protein molecules, called antigens and antibodies. If the red blood cell had only “A” antigen on it, that blood was called type A. These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Apart from the ABO antigens, there is another important antigen on the RBC surface called the Rh antigen.
