Tests and diagnosis
By Mayo Clinic staffTests and procedures used to diagnose autoimmune hepatitis include:
- Blood tests. Testing a sample of your blood for antibodies can distinguish autoimmune hepatitis from viral hepatitis and other disorders with similar symptoms. Antibody tests also help pinpoint the type of autoimmune hepatitis you have.
- Liver biopsy. Doctors perform a liver biopsy to confirm the diagnosis and to determine the degree and type of liver damage. During the procedure, a small amount of liver tissue is removed, using a thin needle that's passed into your liver through a small incision in your skin. The sample is then sent to a laboratory for analysis.
