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.

Key points

  • Anti-M is rarely clinically significant.
  • 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.

Anti-Kpa is an antibody directed to an antigen of the Kell blood group system. The Kell antigens are located on the red blood cell transmembrane glycoprotein known as CD238, and consist of a large group of 35 antigens. Some of these antigens are highly immunogenic, and after the ABO and Rh blood group systems, they are the most common immunogenic group for red blood cells. However, Anti-Kpa itself is extremely rare.
