The Gamma-Glutamyl Transferase (GGT) test is a blood test that measures the level of GGT enzyme in your blood. GGT is found in many organs, especially the liver. It plays a key role in breaking down and transporting proteins and other molecules.
An elevated GGT level may be a sign of liver disease, bile duct problems, or excessive alcohol use. This test is often used in combination with other liver function tests (like ALP, ALT, and AST) to assess liver health.

    Why It’s Done

    The GGT test may be ordered to:
    • Detect Liver or Bile Duct Disorders: Especially when other liver enzyme levels (like ALP) are elevated.
    • Evaluate Alcohol Abuse: Chronic alcohol use can increase GGT levels.
    • Monitor Liver Function: Especially in people taking medications that can affect the liver.
    • Help Diagnose Causes of Jaundice: Or unexplained liver test abnormalities.
    • Assess Bile Duct Blockages: Such as from gallstones or tumors.
    It is particularly useful in differentiating the source of an elevated alkaline phosphatase (ALP) — whether it’s liver or bone-related.

    Preparation

    To prepare for the GGT test:
    • Fasting: You may be asked to avoid eating or drinking (except water) for 8 hours before the test.
    • Avoid Alcohol: Refrain from consuming alcohol for at least 24 hours before the test, as it can raise GGT levels.
    • Medication Disclosure: Inform your doctor about any medications or supplements you’re taking, as some (like phenytoin, barbiturates, or NSAIDs) can affect GGT levels.
    • Avoid Smoking Before the Test: As it may also slightly increase GGT levels.
