Stored serum samples from 169 blood donors found positive for TPHA were tested for antibodies to hepatitis C virus (anti-HCV) and to hepatitis B core (anti-HBc), as evidence of previous HBV infection, a condition known to be sexually transmissible. Only three donors were positive with a 'first generation' anti-HCV and all three failed to confirm with a recombinant immunoblot assay (RIBA). In contrast, 33 (19.5%) of the TPHA-positive donors were positive for anti-HBc. The results suggest that sexual transmission is not a major factor in the spread of HCV.
