Abstract

We report the first case of a clinically significant delayed hemolytic transfusion reaction associated with anti-Aua antibody in an 18-year-old male with beta-thalassemia and pre-existing anti-D, -C, and -Jkb antibodies. Following transfusion with antigen-negative red blood cells, a new anti-Aua antibody was identified, confirmed by a positive Monocyte Monolayer Assay. These findings underscore the importance of vigilance in identifying rare antibodies that may impact transfusion strategies and advanced therapeutic options.
