[Comparative evaluation of different immunological technics for detection of HBsAg].
260 sera from healthy subjects and patients with various diseases (140 subjects with viral hepatitis during the acute stage, 30 with extra-hepatic diseases, 90 blood donors) were tested for HBsAg by the following methods: immunodiffusion according to Ouchterlony, counter-immunelectrophoresis, complement fixation test, passive hemagglutination test, radioimmunoassay. Radioimmunoassay proved to be the more sensitive method. However, the passive hemagglutination test for its simplicity and sensibility, represents the method of choice for screening large population.
