Anti-HBc? When this is positive it means you have:

• A. Immunity due to vaccination
• B. No infection
• C. HBV infection or had it at some time in the past
• D. Active Hep C infection

Answer: (C)

Anti-HBc is antibody to the hepatitis B core antigen, which appears after exposure to hepatitis B virus. Its presence shows that you've been infected with HBV at some point, either currently or in the past. Vaccination induces antibodies to the surface antigen (anti-HBs) and does not produce anti-HBc, so immunity from vaccination would not include anti-HBc. It’s not an indicator of no infection, and it has nothing to do with hepatitis C infection.
