The GGT test (gamma-glutamyl transpeptidase) primarily measures the amount of GGT enzyme in your blood. GGT works as a transport molecule and assists in moving other molecules around your body. Its role is imperative in helping the liver absorb drugs and other toxins. Though GGT is mainly found in the liver, it can also be present in the gallbladder, spleen, pancreas, and kidneys. GGT levels are beyond the normal range when your liver is damaged. Your doctor refers to the GGT blood test along with other tests, mainly alkaline phosphatase (ALP) to check the possibility of liver damage.

The cost of the GGT test is Rs. 120-Rs.250. The price may vary depending on your location.

The Purpose of the GGT Test
The prime purposes of the GGT test are:- To diagnose liver disease
- To find out if your liver is damaged due to liver disease or a bone disorder
- To check for blockages in the bile ducts
- To screen or monitor alcoholic liver diseases
Why is the GGT Test Done?
Your liver plays an important role in producing proteins in your body and excreting waste products from your body. The liver also produces bile, a substance that supports your body in processing fats.Your doctor will recommend a GGT test if he suspects your liver is damaged or if you have liver disease, especially due to alcohol abuse. The GGT test indicates how much of your liver is damaged and which disease you are suffering from. This damage can be due to excessive use of alcohol or other toxic substances, including drugs or poisons.
The symptoms of liver problems include:
- Loss of appetite
- Nausea or vomiting
- Fatigue or lack of energy
- Lower abdominal pain
- Yellow skin and eyes called jaundice
- Dark-colored urine
- Light-colored stool
- Itchy skin
GGT Test Preparation
Sometimes, your doctor may give you advice for fasting before the test. If you are taking certain medications, inform the doctor. Don’t drink alcohol within 24 hours of the test; it may hamper your results.How is the GGT test conducted?
You need to visit a nearby hospital or lab center for this test. A deft nurse or technician is used to collect your blood from your vein. The healthcare provider ties an elastic band around your arm to identify your vein properly. Then, by inserting a needle, the person draws your blood sample and collects it in a vial for further analysis. You may feel a sharp pain when the needle is inserted.What do the Results Mean?
You may get the results either on the same day or the next day. The GGT normal range is 9–48 units per liter (U/L). Normal values can vary depending on your age and sex.Though the GGT test helps you in diagnosing liver disease, it can’t identify the cause. If your GGT level is beyond the normal value, you may need more tests for further analysis. Generally, the higher the GGT level indicates liver disease.
Some of the health conditions that may increase your GGT value are
- Excessive use of alcohol
- Chronic viral hepatitis
- Inadequate blood flow to the liver
- Liver tumor
- Cirrhosis or scarred liver
- Overuse of certain drugs or other toxins
- Heart failure
- Diabetes
- Pancreatitis
- Fatty liver disease
