The occurrence of antibody markers of hepatitis B virus infection in an HBsAg-negative blood donor population.
Anti HBs, anti-HBc and anti-HBe were tested in blood donors negative for HBsAg by radio- and enzyme-immunoassay. In this population 6.4% of the donors were positive for at least one type of antibody to HBV: 4.0% for anti-HBs, 2.3% for anti-HBc and 4.3% for anti-HBe. Two sera (0.2%) were exclusively positive for anti-HBc, eight sera (2.2%) were weakly positive only for anti-HBe. Further studies of the infectivity of such samples might be of interest.
