Preventing antibody positive delayed hemolytic transfusion reactions in sickle cell disease: Lessons learned from a case.

The presented case of an antibody positive DHTR illustrates several concepts critical to the prevention of this complication. RBC alloantibodies must be detected and this information must be shared. Prophylactic C/c, E/e, K antigen matching is helpful for patients with SCD, but systems must be in place to identify these patients. Patients transfused at multiple different hospitals are especially at risk for this complication and efforts are needed to prevent them from suffering a DHTR.
