Abstract

The Kell blood group system is complex, contains many antigens, highly immunogenic, and potent in triggering immune reactions. Antibodies to Kell blood group system are the most common immune red cell antibodies, following ABO and Rh. However, among the anti-Kell antibodies; anti-Kpa is extremely rare. We report an interesting case of Anti-Kpa in a 59-year-old female patient of Non-Hodgkin's Lymphoma, post radiotherapy, who first developed warm autoantibody and later developed anti-Kpa alloantibody on multiple transfusions.
