HIV-1 antibody positive hepatitis B surface antigen serum in a dental school patient population

Abstract Testing for human immunodeficiency virus antibody (anti-HIV-1) in patients positive for hepatitis B surface antigen has never been performed in a dental school patient population. In this population there was a 2.8% positive reactivity for HIV-1 antibodies in subjects who were also positive for hepatitis B surface antigen. An enzyme-linked immunoassay with a repeat test and confirmation with a Western blot technique were used.
