    Research Summary

    Dr. King’s research focuses on two areas: 1) the problem of alloimmunization due to either multiple transfusions or fetal maternal incompatibility, and 2) novel indications for apheresis. Her interests involve the clinical complications related to red cell alloimmunization, specifically delayed hemolytic transfusion reactions and the phenomenon of bystander hemolysis. She is interested in the transfusion-related issues that complicate the course of patients with sickle cell disease, especially those issues due to alloimmunization and multiple transfusions.
