title: HL-A matching in thrombocyte and leukocyte transfusions.
abstract: A panel of 150 Rh+ and Rh-- donors was tested by the NIH-microcytotoxicity test against 90 antisera determing 21 HL-A antigens. For platelet and leukocyte transfusions, donors compatible in ABO and Rh groups as well as in HL-A antigens, were used. In some cases the donor and recipient were compatible in three HL-A antigens, in other cases the degree of compatibility was less satisfactory. Platelet and leukocyte concentrates were prepared by double thrombo- and leukocyte-pheresis. Before transfusions the cross cytotoxicity test with donor's lymphocytes was performed. No transfusion accidents occurred; in some patients a beneficial effect was noticed.
