title: [Detection of anti-HBAg by solid phase radioimmunoassay using labeled human antibody].
abstract: A new solid-phase radioimmunoassay technique for the detection of anti-HBAg is described. The test is characterized by a neutralization step of guinea-pig anti-HBAg by means of HBAg-RIA positive pooled sera. The first results obtained using this technique gave 21 anti-HBAg positive sera (26.9%) among 78 institutionalized subjects. One of these sera was HBAg positive at the same time.
