    Abstract:
    In present study, a method for genotyping for human platelet antigen (HPA) systems by means of the polymerase chain reaction amplification with sequence-specific primers (PCR-SSP) technique was developed and employed to determine the human platelet antigen frequencies in the Chinese population. Primers sets were designed to allow PCR amplification for five systems using the same assay conditions. Platelets from 110 random Chinese blood donors were typed for human platelet alloantigens HPA-1 to -5 by the method. The results showed that the HPA genotypic frequencies observed in the 110 donors were 0.91 and 0.09 for HPA-1a and HPA-1b, 0.86 and 0.14 for HPA-2a and HPA-2b, 0.60 and 0.40 for HPA-3a and HPA-3b, 0.92 and 0.08 for HPA-4a and HPA-4b, and 0.85 and 0.15 for HPA-5a and HPA-5b, respectively. In conclusion the method is feasible and practical and may be available to typing for HPA in the clinical laboratories.
