High‐frequency antigen Ena (MNS 28) is expressed on glycophorin A (GPA). En(a−) individuals can form anti‐Ena when exposed to GPA. A Thai patient formed an antibody that reacted against all reagent red blood cells (RBCs). The patient received incompatible blood resulting in a fatal haemolytic transfusion reaction (HTR). This study aimed to characterize the antibody detected in the patient and investigate the cause of HTR.
