How do you know if you have hepatitis A?

If you find you have symptoms of hepatitis A or you know you have been in close contact with someone who has hepatitis A, you should contact your healthcare provider.

How is hepatitis A diagnosed?

Your healthcare provider will listen to your symptoms and will take a blood test to confirm the diagnosis of hepatitis A. If the test finds immunoglobulin M (IgM) antibodies, you have an acute hepatitis A. If there are antibodies, but not IgM antibodies, you are immune to the virus either because you had a case of it and recovered, or you got the hepatitis A vaccine.
