Delayed hemolytic transfusion reaction with multiple alloantibody (Anti S, N, K) and a monospecific autoanti-JK(b) in intermediate β-thalassemia patient in Tabriz.

It appears that delayed hemolytic transfusion reactions may occur several days after the administration of donor red cells is true even though they have been shown to be compatible in cross match tests by the antiglobulin technique. A specific case was observed in our center, which confirms the fact. The patient was a 37-year-old male suffering from intermediate β-thalassemia.
