What it measures
- Hepatitis B surface antigen (HBsAg) — The main marker: if present, it means the virus is in your blood and you can pass it to others.
- Hepatitis B surface antibody (anti-HBs) — Often tested alongside HBsAg; a positive result usually means you are protected from hepatitis B, either from vaccination or past infection.
- Hepatitis B core antibody (anti-HBc) — Another marker that can show if you have ever been exposed to the virus, even if it is no longer active.
