Delayed hemolytic transfusion reactions usually occur as a result of a secondary immune response with maximal hemolysis occurring seven days posttransfusion. We report a delayed hemolytic transfusion reaction in which hemoglobinuria, anemia, and reticulocytosis developed four weeks after transfusion. The incriminated antibody, anti‐C, was first detected eight weeks posttransfusion using enzyme‐treated red blood cells. We conclude, that in all likelihood, this hemolytic transfusion reaction was due to a primary immune response, this case illustrates the importance of sequential testing in cases of suspected transfusion reactions.
