title: Haematological differences in three population groups.
abstract: The increased absolute lymphocyte counts of Indians and Blacks in comparison with Whites, observed in a former study, were shown, in a study on blood donors, to occur in women rather than men of these two groups. Neutrophil counts showed no sex differences, but were significantly highest in Whites and lowest in Blacks. Indians of both sexes had significantly higher mean red cell counts, together with smaller red cells, than subjects in the other two groups. In no group was a significant correlation observed between body mass and haemoglobin level.
