ABO blood groups and Australia antigen.

The distribution of ABO blood in two groups of people with Australia antigen was studied (121 blood donors and 128 patients) and in 3,091 controls was investigated. There was a significant excess of A in comparison with o when the two groups were combined, and when the two groups were tested for (A + B): (AB +O) individually and together, both were found to be statistically significant. The results are discussed.
