What it measures

  • Hepatitis B surface antibody (anti-HBs) — Shows if you are immune, usually from a vaccine.
  • Hepatitis B surface antigen (HBsAg) — If positive, indicates a current infection.
  • Hepatitis B core antibody (anti-HBc) — Can show a past or ongoing infection.

Results and what they mean
