title: Quantitative and qualitative studies on hepatitis B antigen. Titer and subtypes in acute virual hepatitis patients and blood donors.
abstract: Hepatitis B antigen (HB Ag) titer and subtype were determined in blood samples obtained from 270 HB Ag-positive acute viral hepatitis (AVH) patients, as well as in 100 HB Ag-positive blood donors. The percentage distribution of the HB Ag titer shows a shift towards lower titers in the case of "healthy carriers". In both AVH patients and blood donors the "ay" antigenic subtype was found to be predominant.
