Delayed Hemolytic Transfusion Reaction in Sickle Cell Disease

Delayed hemolytic transfusion reactions are potentially life-threatening complications observed in patients with sickle cell disease. We review the clinical features, pathophysiology, laboratory evaluation, and management of this complication. It is important that delayed hemolytic transfusion reactions be included in the differential diagnosis of acute pain episodes following a red blood cell transfusion in a patient with sickle cell disease.
