title: A new reversed passive hemagglutination test for detection of HBsAg.
abstract: A new reversed passive hemagglutination test for HBsAg, termed Raphadex B, has been developed using immunochemically purified chimpanzee anti-HBs bound to stabilized human erythrocytes. The test has been found to have equivalent sensitivity to the Ausria 125I radioimmunoassay, and detected a similar number of HBsAg-containing specimens in screening of volunteer blood donors. This method offers an economical approach to third generation methodology for hepatitis B screening of blood donors.
