The antigen McCa is detected in 98.5 and 96.7 per cent of the American Caucasian and Negro populations respectively. In population studies with anti-McCa and anti-Kna, a strong association was demonstrated between the two antigens, with 53 per cent of McC(a-) sample being Kn(a-) compared with a reported frequency for Kn(a-) of only 0.19 per cent.
