Description
ABO Group and Rh Type – ABO type and Rh are needed to identify candidates for Rh immune globulin and to assess the risk of hemolytic disease of the newborn.
Blood type tests categorize your blood according to the major human blood group (ABO) system. A person’s ABO type depends upon the presence or absence of two genes — the A and B genes. These genes determine part of the configuration of the red blood cell surface. Possible ABO blood groups include O, A, B, or AB.
