The Hepatitis A Immunity Test checks whether you have antibodies that protect against hepatitis A, a liver infection caused by the hepatitis A virus. It is often ordered to confirm immunity from a past infection or vaccination, or to see if vaccination is needed.

What it measures

  • Total Hepatitis A Antibodies — Detects both IgM and IgG antibodies against hepatitis A virus.
  • IgG Antibodies — Indicates past infection or vaccination; suggests long-term protection.
  • IgM Antibodies — Suggests recent infection; not usually present after vaccination.

Who it is for

This test may be ordered for people at higher risk of hepatitis A, those with liver disease, travelers to areas where the virus is common, or anyone wanting to check their immunity status.

Preparation

No fasting or special preparation is needed for this blood test. You can eat and drink normally before your appointment.

Results and what they mean

Results are typically reported as positive (immune) or negative (not immune), sometimes with a numerical value. A positive result generally means you have antibodies that protect against hepatitis A, while a negative result means you may need vaccination. A clinician interprets your results in the context of your health history; this information is not medical advice.
