What this test is
The Hepatitis A Antibody Test (IgM) is a blood test that detects immunoglobulin M antibodies directed against the hepatitis A virus. IgM antibodies usually appear early after infection and are a sign of an acute or recent infection. The test is different from tests that check for IgG antibodies, which can indicate past infection or vaccination.
What it measures
- Hepatitis A IgM antibody — reflects a recent or acute hepatitis A infection
- Hepatitis A IgG antibody — sometimes measured separately to show past infection or vaccination
What the test involves
A healthcare professional collects a small sample of blood, usually 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 when someone has symptoms that could be caused by hepatitis A, such as jaundice, fatigue, nausea, or abdominal discomfort. It may also be ordered after a known or suspected exposure to the virus, or to help investigate an outbreak.
Preparation
In general, no special preparation is needed for this blood test, but you should follow the instructions provided by the collection lab. Tell the lab about any medications or health conditions if they ask.
How results are reported
Results are typically reported as positive, negative, or sometimes equivocal, along with a reference range from the performing laboratory. Reference ranges and reporting formats can vary between laboratories, so your clinician will interpret the result in the context of your health history.

FAQ
Frequently asked questions
What does a positive IgM result mean?
A positive IgM result generally suggests a recent or acute hepatitis A infection. However, a positive result alone does not confirm the diagnosis, and your clinician will consider your symptoms, history, and other tests.
Can this test tell if I had hepatitis A in the past?
No, this test specifically looks for IgM antibodies, which are usually present only during a recent infection. A different test, such as hepatitis A IgG, is used to check for past infection or immunity from vaccination.
How long does it take to get results?
Turnaround time can vary by laboratory, but results are often available within a few business days. Your ordering clinician or the collection lab can give you a more specific timeframe.
Do I need to fast before this test?
Fasting is not typically required for a hepatitis A antibody test. However, always follow the preparation instructions given by the lab that will collect your sample.
