Which finding best indicates hepatocellular damage from alcohol?

• A. AST:ALT Ratio Greater Than 2:1
• B. ALT Greater Than AST
• C. GGT Less Than AST
• D. Bilirubin Normal

Answer: (A)

Alcohol-related hepatocellular injury classically shows a pattern where AST rises more than ALT, often with an AST to ALT ratio greater than two to one. This occurs because alcohol preferentially damages mitochondria, where a large portion of AST is located, leading to a relatively larger release of AST compared with ALT. ALT is more liver-specific but usually rises to a lesser extent in this pattern, which helps distinguish alcohol-related damage from other liver diseases where ALT can be higher or more balanced. While GGT can be elevated with alcohol use, and bilirubin can be normal or elevated depending on injury severity, the strongest indicator of alcohol-induced hepatocellular damage among the options is the AST:ALT ratio greater than two to one.
