Abstract
RED-CELL A and B antigens are primarily intrinsic membrane glycoproteins that become attached during erythropoiesis by specific A and B transferase enzymes.1 A and B antigens may also be acquired by red-cell adsorption of A and B substances present in the plasma of secretors.2 The acquisition or loss of ABO antigens has been reported in association with cancers, hematologic disorders, infections, and bone marrow transplantation.3
