How Do Doctors Diagnose Alcoholic Hepatitis?
Published: Nov 07, 2023
Diagnosing alcoholic hepatitis can be complex, involving a mix of clinical assessments and tests. Here's how doctors determine if alcohol is harming your liver.
Key Diagnostic Steps
To diagnose alcoholic hepatitis, doctors start with a detailed alcohol use history and clinical evaluation. They look for symptoms like jaundice and fever and check for an elevated AST:ALT ratio. If symptoms and history align, this often points to alcoholic hepatitis.
Role of Laboratory Tests
Lab tests play a crucial role in diagnosis. Elevated aminotransferases and bilirubin levels, along with a high INR, are common indicators. These tests help rule out other liver conditions, ensuring that alcohol is the primary cause of liver inflammation.
When Is a Liver Biopsy Needed?
A liver biopsy might be necessary if the diagnosis is uncertain or other liver diseases are suspected. This procedure provides a clearer picture of liver health, confirming alcohol-induced damage. It's especially useful in complex cases with overlapping symptoms.
