Immune hemolytic anemia: a report of two cases.

The transfusion-medicine specialists and physicians are often in a difficult situation when the patient has severe worsening anemia and all the blood is mismatched. This situation can arise in patients with red cell autoantibodies or alloantibodies due to previous transfusions. We report two cases of immune hemolysis - one due to warm auto antibodies and the second due to alloimmunization from multiple transfusions.
