Peculiarities of some blood group systems in blood

Abstract

There are 29 different blood group systems including the major ABO type and Rh type. As each blood group systemhas specific antigens on the surface of erythrocytes they become important parameters to be checked before blood transfusion. The other major blood group systems are- MNS, P, Kell, Kidd, Bombay and Lewis. They generally are not considered clinically important but still we shouldn’t ignore them as it may cost the patient’s life.
