generic term for any inherited antigen found on the surface of erythrocytes that determines a blood grouping reaction with specific antiserum; antigens of the ABO and Lewis blood groups may be found also in saliva and other body fluids; the genes controlling development of blood group antigens vary in frequency in different population and ethnic groups.
