About this test
This panel checks whether a person has protective immunity against hepatitis A and hepatitis B, often after vaccination or prior infection. It measures antibodies that reflect protection along with markers that can reveal past or current hepatitis B infection. Clinicians order it to confirm vaccine response, verify immunity for school or work, or clarify ambiguous hepatitis histories.
What this test measures
- Hepatitis A IgG antibody Indicates immunity from past infection or vaccination.
- Hepatitis B surface antibody (anti-HBs) Indicates protective immunity.
- Hepatitis B core antibody (anti-HBc) Can indicate past or ongoing hepatitis B infection.
- Hepatitis B surface antigen (HBsAg) May indicate a current hepatitis B infection.
Who this test may be right for
- People confirming immunity after vaccination.
- Individuals with unclear hepatitis vaccination records.
- Those with occupational immunity requirements.
- People with possible past hepatitis exposure.
- Anyone with abnormal liver findings being evaluated.
Before your visit
- No fasting is required for immunity testing.
- Take usual medications unless told otherwise.
- Bring vaccination records if available.
- Share any history of hepatitis or immune conditions.
- A standard blood draw is used for the sample.
Understanding your results
A positive hepatitis A IgG and a positive hepatitis B surface antibody generally indicate protective immunity. A reactive anti-HBc with negative anti-HBs can suggest past infection rather than vaccination, and a reactive HBsAg may indicate a current infection requiring follow-up. Because markers can overlap, the pattern is important. Discuss immunity results with a healthcare provider.
