Alananine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) are key enzymes measured in clinical chemistry to assess liver function and detect hepatobiliary or systemic disease. Together, these enzymes provide a complementary panel for evaluating liver damage patterns and distinguishing between hepatocellular and cholestatic disease. Signosis’ Liver Enzyme Assay Combo Kit provides a comprehensive solution for measuring the activity of these key liver enzymes in a single, streamlined workflow.
