A Case of Delayed Hemolytic Transfusion Reaction Due to Anti-Jka Antibody / 대한수혈학회지

We report a case of delayed hemolytic transfusion reaction due to anti-Jka antibody. The patient was a 68-year-old women who was admitted for general weakness after subtotal thyroidectomy. She received two units of packed red cells because of anemia. On the fifteenth post-transfusion day, she developed a marked fall in hemoglobin and mild hyperbilirubinemia. Direct antiglobulin test was positive. Anti-Jka antibody was identified in her serum, and her phenotype of Kidd blood group was Jk(a-b+). Therefore the anti-Jka antibody was thought to be the possible offending antibody in this delayed hemolytic transfusion reaction.
