Thrombocytopenic patients who have become refractory to platelet transfusions from random donors will usually respond to HL-A compatible platelets with normal increments and hemostatic improvement. In our experience with unrelated HL-A typed donors, HL-A identity is unnecessary. Donors without excess antigen are compatible and even many donors with 1 excess antigen can be used, at any rate in immunosuppressed patients. Thus successful substitution of platelet becomes possible in refractory patients when family donors cannot be used.
