What do high levels of GGT mean?

High levels of gamma-glutamyl transferase (GGT) can indicate liver disease, bile duct obstruction, or excessive alcohol consumption. Elevated GGT levels may also signal conditions such as pancreatitis or heart failure. It is often used in conjunction with other liver function tests to assess liver health and diagnose potential issues. However, elevated GGT alone is not definitive for a specific condition and should be interpreted by a healthcare professional.
