What it measures
- Hepatitis A IgG antibody — Shows past infection or protection after hepatitis A vaccination.
- Hepatitis B surface antibody (anti-HBs) — Shows immune protection, usually from vaccination.
- Hepatitis B surface antigen (HBsAg) — A marker that can indicate current hepatitis B infection.
- Hepatitis B core antibody (anti-HBc) — Helps distinguish past or current infection from vaccination alone.
- Hepatitis C antibody — Sometimes added to screen for hepatitis C exposure.

Frequently asked questions
Do I need to fast for this test?
No. Fasting is not required for hepatitis immunity or vaccine testing.
Can this test tell if I am protected from hepatitis B?
A positive hepatitis B surface antibody usually means you are protected, but your clinician will interpret it with your history.
How long after vaccination should I get tested?
Ask your clinician. Testing too soon after a vaccine series may give unclear results.
Is this test the same as a hepatitis screening test?
Not always. Immunity testing focuses on protection, while screening looks for current or past infection.
