Tests and diagnosis
By Mayo Clinic staffBecause 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 an effort to reach a diagnosis, your doctor may include one or more of the following steps:
- Medical history and physical exam. Your doctor will ask you questions about your health history, including alcohol use, and conduct a physical exam.
- Blood tests. These check for high levels of certain liver-related enzymes, such as aspartate aminotransferase (AST) and alanine aminotransferase (ALT).
- Ultrasound. Your doctor may use this noninvasive imaging test to view your liver and to rule out other liver problems.
- Liver biopsy. In this procedure, a small sample of tissue is removed from your liver and examined under a microscope. Liver biopsy usually involves inserting a long, thin needle through your skin and into your liver in order to draw out a sample of tissue.
