Gamma-glutamyl Transferase (GGT) Test
What is GGT Test?
The Gamma-glutamyl transferase (GGT) test is a type of laboratory test that measures the level of the enzyme gamma-glutamyl transferase in your blood. This enzyme is important for proper metabolism of amino acids, the building blocks of proteins. High levels of GGT can indicate the presence of certain liver conditions, such as hepatitis, cirrhosis, or bile duct obstruction. It may also be used along with other tests to diagnose and monitor treatment for alcoholism.
Why GGT Test Is Used?
GGT is mainly used to detect liver problems, but may also be used to monitor alcohol consumption, as it can increase with chronic drinking. It can also detect the presence of drugs in the bloodstream that can be used to treat various conditions, such as antibiotics, anti-depressants, corticosteroids, and anticonvulsants.
Types of GGT Test
GGT tests can be done with a quantitative or qualitative method. Quantitative GGT tests measure the actual amount of GGT in the blood, while qualitative tests are used to determine if the level is high or low.
How to Prepare for GGT Test?
Before having a GGT test, it is important that you discuss your medical history and current medications with your doctor. Some medications may interfere with the test’s accuracy. You should also avoid alcohol and fatty foods for 24 hours before the test to get accurate results.
What Is the Procedure?
During a GGT test, a technician will draw a small amount of blood from a vein in your arm. The sample will be sent to a laboratory for analysis. A qualified technician will then examine the sample and measure the level of GGT present in the blood.
What Are the Risks?
GGT tests are generally safe and do not pose any major risks. However, you may experience minor discomforts such as bruising, bleeding, and soreness at the puncture site. If you experience any severe pain or bleeding, contact your doctor immediately.
When to Have GGT Test?
Your doctor may suggest a GGT test if he or she suspects you may have a condition such as hepatitis, cirrhosis, alcoholism, or bile duct obstruction. It is also used to monitor certain treatments related to liver or kidney disease.
