The GGT (Gamma-Glutamyl Transferase) blood test measures the level of GGT enzyme in the blood, which helps assess liver function and detect liver disease, bile duct obstructions, or excessive alcohol consumption. While not specific, it is often used alongside other liver function tests to monitor or diagnose liver-related conditions.
