The distributions of ABO blood group phenotypes and the ABH secretor status frequencies showed no significant differences between these populations. In contrast, there was a difference regarding the frequency of the red blood cell Le(a-b-) phenotypes, associated with erythrocyte/saliva discordance, as confirmed by the observation that individuals with Le(a-b-) red cells have the Lewis antigen in their saliva, resulting in a nongenuine Le(a-b-) phenotype, whose frequency was higher in Alcântara.engAcesso AbertoAntígenos de grupo sanguíneoSistema LewisSistema do grupo sanguíneo de LewisSistema do grupo sanguíneo ABHNegro (Raça)Cametá - PAAlcântara - MAPará - EstadoMaranhão - EstadoAmazônia brasileiraArtigo de Periódico
