title: Frequency of PLA1 in blacks.
abstract: Racial frequencies of platelet-specific antigens in racial groups other than whites have not been studied. The prevalence of PLA1 was determined in white and black blood donors. Two hundred forty-two of 243 blacks were PLA1-positive (99.6%), compared with 242 of 250 whites (96.8%) (p = 0.021). This black population has the highest frequency of PLA1 yet reported.
