Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like fever, fatigue, nausea, or jaundice, or if you’ve recently traveled to areas with higher hepatitis A risk. It’s also used for screening before certain procedures or vaccinations to ensure you’re not at risk of infection.

What to Expect Before the Test

No special preparation is needed. You may donate blood or have a blood sample drawn from a vein in your arm. If you’re tested for antibodies, you’ll likely have a small needle inserted to collect a few drops of blood.

What the Test Results Mean

Positive results indicate the presence of hepatitis A antibodies, which may mean you’ve had past infection or vaccination. Negative results suggest no current infection or exposure. Follow-up testing may be needed if symptoms persist.

Common Symptoms of Hepatitis A

Hepatitis A can cause flu-like symptoms, including fatigue, abdominal pain, loss of appetite, nausea, and dark urine. Some people may also experience jaundice (yellowing of the skin and eyes). If you experience these symptoms, inform your healthcare provider.

Frequently asked questions

What does a positive result mean?
A positive result means you have antibodies against hepatitis A, which could indicate past infection or vaccination. This doesn’t mean you’re currently infected, but it confirms your immune system has been exposed to the virus or vaccinated.
How long do I need to wait for results?
Results are typically available within a few days to a week, depending on your lab. Your healthcare provider will contact you with the results.
Can I still get hepatitis A if my antibody test is negative?
Yes, a negative test means you currently don’t have antibodies, but it doesn’t guarantee you’re immune. You could still get infected if exposed to the virus. Consider vaccination if you’re at risk.
