We are pleased to present the seventh annual report describing transmissible blood-borne infection surveillance. High quality and timely surveillance is central to the safety of the blood supply. This includes monitoring of transmissible disease markers that the blood is tested for (including bacteria) and investigation of any reports of possible transfusion transmission, as well as a horizon scan for any new pathogens that may pose a risk.

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.
