MNSs and Miltenberger frequencies in 211 Chinese.
In serial MNSs tests on blood samples from 211 Chinese, 10 Mi(a+) were found, 9 of which were shown to belong to Miltenberger cell class III (Mi-III); it was assumed by analogy that this also applies to the tenth. The frequency of Mi-III in this Chinese series is thus 4.7%, almost 500 times higher than in Whites. Seventy persons in the series were tested for the Stones antigen: 2St(a+) were observed. Attention is drawn to the 'variant N' reactions of M Mi-III blood: positive with Vicia graminea extract, weakly positive with rabbit, negative with human anti-N. The reactions can be a source of error in MN tests on Chinese bloods.
