Hepatitis A, B, and C immunity testing is a blood test that checks whether you are protected against or currently infected with these three viruses. It is often ordered to confirm immunity from vaccination or past infection, or to screen for exposure when symptoms or risk factors are present.
What it measures
- Hepatitis A antibody (total or IgG) — Shows if you are immune from past infection or vaccination.
- Hepatitis B surface antibody (anti-HBs) — Indicates protection from vaccination or resolved infection.
- Hepatitis B surface antigen (HBsAg) — If positive, suggests current hepatitis B infection.
- Hepatitis B core antibody (anti-HBc) — Can show past or ongoing infection; helps clarify other results.
- Hepatitis C antibody (anti-HCV) — Screens for exposure to hepatitis C; a positive result needs follow-up.
Who it is for
A clinician may order this test for people with symptoms like jaundice or fatigue, those with known exposure risks, or anyone wanting to check immunity before travel or vaccination.
Preparation
No fasting is required. Tell your clinician about any medications or recent vaccines, as timing can affect some results.
Results and what they mean
Results are reported as positive, negative, or numeric values for each marker. Your clinician interprets them together with your history to determine immunity or infection status. This is general information only and not medical advice; discuss your results with a qualified healthcare professional.
