The Gamma-Glutamyl Transferase (GGT) Test measures the level of the GGT enzyme in the blood. GGT is mainly found in the liver and bile ducts. This test helps assess liver health, detect bile duct problems, and evaluate conditions that may affect liver function.
1.GGTP (Gamma GT)
Measures Gamma-Glutamyl Transferase enzyme levels in the blood to evaluate liver function and detect possible liver or bile duct problems.
Also known as: GGT Test, Gamma GT Test, GGTP Test, Gamma-Glutamyl Transpeptidase Test
The Gamma-Glutamyl Transferase (GGT) Test is a blood test that measures the amount of GGT enzyme present in the bloodstream. GGT is mainly produced by the liver and plays a role in transporting amino acids and processing substances in the body.
Changes in GGT levels may indicate liver stress, bile duct obstruction, alcohol-related liver damage, or other conditions affecting liver function. The test is often performed along with other liver function tests to get a complete picture of liver health.
The GGT Test is a liver enzyme test that measures the level of Gamma-Glutamyl Transferase in the blood.
GGT is found mainly in:
When the liver or bile ducts are damaged or irritated, GGT levels may increase in the blood. This test helps doctors evaluate liver and bile duct function.
Doctors may recommend a GGT Test to:
The test may be suggested if you experience symptoms such as:
Benefits of the GGT Test:
A GGT Test may be recommended for:

Usually, no special preparation is required for a GGT Test.
Before the test:
Your doctor may ask you to avoid certain foods, medications, or alcohol before the test depending on your health condition.
| Parameter | Normal range |
|---|---|
| GGTP (Gamma GT) | Approximately 9–48 U/L |
| Note | Normal ranges may vary depending on age, sex, laboratory methods, and health conditions. Your report will mention the reference range used by the laboratory. |
| A higher GGT level does not always indicate a specific disease. Doctors usually interpret GGT results along with other liver tests and your medical history. |
Reference ranges can differ between labs. Your report shows the range used by the lab.
A GGT Test is a blood test that measures Gamma-Glutamyl Transferase enzyme levels to assess liver and bile duct health.
The test helps detect liver damage, bile duct problems, and monitor liver function during certain treatments.
Fasting is usually not required. However, follow your doctor's instructions if the test is performed with other blood tests.
High GGT levels may be associated with liver conditions, bile duct problems, alcohol consumption, certain medications, or other health factors.
