Anti-HBsAg assay using the Ausria system with standard antigen dilutions.
A simple modification of the radioimmunoassay Ausria I and Ausria II was employed for detecting anti-HGsAg using the inhibition of a constant amount of HBsAg. The highest incidence of anti-HGsAg was demonstrated in follow-up patients recovering from viral hepatitis B (82%) and in hemophilia patients (79%). Lower frequencies were observed in patients with chronic aggressive hepatitis or liver cirrhosis (23%), patients with chronic rheumatoid arthritis (16%), family contacts of patients with viral hepatitis B (10%) and blood donors (3.4%). No difference in sensitivity for the presence of anti-HBsAg was found between the Ausria I and the Ausria II test.
