A very small percentage of red blood cell units are manufactured from blood donors with red cell antibodies. These donors may have antibodies directed against common non-ABO antigens detected during routine screening or may represent a rare blood donor with the corresponding antibody.

  • Patients with anti-M should receive red blood cell units crossmatch compatible by IAT or equivalent using IgG antihuman globulin for transfusion.

Anti-Le, commonly anti-Lea, Leb, or Leab, are antibodies directed to antigens of the Lewis blood group system. The Lewis antigens are glycoproteins that are found on the surface of many cells and secreted in various body fluids. As such, Lewis, along with ABO and H are sometimes referred to as “histo-blood groups,” given the fact they are present on many different tissue types.
