The ABO group, Lewis type and secretor status were determined in 546 normal individuals (241 male, 305 female). Their serum was tested at 4 degrees C for agglutination of group O red blood cells; the antibody was presumed to be auto-anti-I; the results were expressed as a score. Among non-A female donors, the score was higher for secretors than nonsecretors (p less than 0.05). Among non-A secretors of both sexes, female donors had a higher score than male donors (p less than 0.05). These results suggest that the level of anti-I in the serum of normal individuals may be affected by the donor's ABO group, secretor status and sex.
