liver enzyme tests

Liver enzyme tests measure specific proteins released into the blood when liver cells are damaged or inflamed. Common enzymes tested include AST (aspartate aminotransferase), ALT (alanine aminotransferase), alkaline phosphatase, and GGT (gamma-glutamyl transferase). Elevated levels can indicate liver conditions such as hepatitis, fatty liver disease, or alcohol-related liver damage. These tests help doctors assess liver health, identify issues early, and monitor ongoing treatment. It’s important to interpret results in context with other tests and clinical information, as various factors can influence enzyme levels.
