The hepatitis A antibody test is a blood test that checks whether you have antibodies against hepatitis A virus, which can indicate a past infection, a current infection, or vaccination. It is often ordered when someone has symptoms of liver inflammation or when a possible exposure to the virus needs to be checked.

What it measures

  • IgM antibodies — Usually appear early and suggest a recent or current infection.
  • IgG antibodies — Usually appear later and can remain for life, showing past infection or vaccination.
  • Total antibodies — A combined measurement that may be used for screening.
  • Liver enzymes (if included) — May be checked alongside to see how the liver is working.

Who it is for

A doctor or other clinician typically orders this test when a person has hepatitis symptoms, known exposure, or risk factors, or when immunity from vaccination needs to be confirmed.

Preparation

No fasting or special preparation is usually required. Tell your clinician about any medications, supplements, or recent vaccinations.

Results and what they mean

Results are reported as positive, negative, or sometimes equivocal for each antibody type, and a clinician interprets them alongside your history and other tests. A positive IgM result can suggest recent infection, while a positive IgG result can suggest past infection or vaccination. This is general information only and is not medical advice; talk with a qualified clinician about your results.
