Platelet antigen typing of blood donors is not routinely performed. Usually, ABO-matched platelets are transfused. In situations where the recipient has a human platelet-associated (HPA) antibody resulting in refractoriness to platelet transfusions, post-transfusion purpura or neonatal alloimmune thrombocytopenia, HPA-typed platelets may be required. Having a panel of HPA-typed donors would be helpful. This study utilised PCR-RFLP and PCR-SSP methods to determine the HPA-1, 3, 5 genotypes of 1,000 blood donors to establish a panel of HPA homozygous donors who could donate platelets for patients with anti-HPA-antibodies. The study demonstrates the HPA genotype frequencies in a Western Australian blood donor population and has identified donors who are homozygous for the ″aa″ and ″bb″ genotypes for HPA-1, 3 and 5. The Australian Red Cross Blood Service-NW Region can now use these data to develop a panel of HPA-1, 3 and 5 ″aa″ and ″bb″ homozygous platelet donors, which can be accessed for patients with HPA antibodies reqtiring platelet transfusion.
