title: [Frequency of Australia antigen in a heterogenous population and estimation of 3 various methods of research].
abstract: 4,000 samples of serum for Australia antigen research were examined by electrosineresis. From these 4,000 serums two groups were formed afterwards: the first formed by 2,466 samples which were examined also by immunodiffusion; the second formed by 1,093 samples which were examined also by latex test; no common serum was in the two groups at the same time. AU frequence in this population sample is within the high limits of the national average. A comparison of the used methods showed the following: immunodiffusion given the smallest number of positive results; electrosineresis given other positive results besides those found out by immunodiffusion; latex test given the largest number of positive results, but greatly discordant from electrosineresis. The achieved results are examined.
