What this test is
This blood test looks for antibodies your body makes in response to the hepatitis A virus, either from a past infection or from vaccination. It helps determine if you have immunity, meaning your body is prepared to fight off the virus.
What it measures
- Hepatitis A virus total antibodies — Reflects past infection or vaccination, indicating immunity
- IgG antibodies — Suggests long-term immunity from past infection or vaccination
- IgM antibodies — May indicate a recent or acute infection
What the test involves
A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to see if you are already immune to hepatitis A before recommending vaccination, or to investigate a possible past infection. It can also be used in certain public health or occupational settings where immunity status is relevant.
Preparation
Preparation for this test is usually minimal, but you should follow any specific instructions provided by the collection lab. This may include fasting or other requirements, so always check with the lab beforehand.
How results are reported
