Tests and diagnosis

By Mayo Clinic staff

Because there are numerous liver diseases and a wide range of factors that can cause them, including viral infections, drugs and environmental toxins, diagnosing alcoholic hepatitis can be challenging. In addition to a full medical history, including questions about your drinking habits and a physical exam, you're likely to have certain tests, including:

  • Blood tests. These check for high levels of certain liver-related enzymes: gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST) and alanine aminotransferase (ALAT). Elevated levels of these enzymes are likely to occur in people with alcoholic hepatitis. You may also have tests to check for viral infections that affect the liver, such as hepatitis B and C.
  • Ultrasound. Your doctor may use this noninvasive imaging test to view your liver — in people with alcoholic hepatitis, the liver may be enlarged — and to rule out other problems such as gallstones or bile duct obstruction.
  • Liver biopsy. In this procedure, a small sample of tissue is removed from your liver and examined under a microscope. Your doctor is likely to use a thin cutting needle to obtain the sample. Needle biopsies are relatively simple procedures requiring only local anesthesia, but your doctor may choose not to do one if you have bleeding problems or severe abdominal swelling (ascites). Risks include bruising, bleeding and infection.
