What is Gamma Glutamyl Transpeptidase (GGT)?

Gamma-glutamyl transpeptidase (GGT) is an enzyme found throughout the body, with higher concentrations in the liver. Elevated GGT levels are often seen when a person's liver or bile ducts have been damaged due to disease.

What is a GGT blood test?

In a GGT blood test, this enzyme levels will be analyzed in your bloodstream. Generally, an increased level of GGT in the blood indicates that liver damage has occurred but does not point specifically to a cause for this. It is usually ordered with or followed by other liver tests such as AST, ALT, ALP and bilirubin. Your doctor can use this information to determine what kind of liver disease you have and explore treatment options.

What is a GGT blood test used for?

GGT is the first enzyme to increase when there is an obstruction of the bile ducts from the liver to the intestines due to stones or a tumor and is, therefore, useful to detect liver and bile conduct issues. GGT is also used to monitor alcohol abuse and associated liver damage.

Do I need to visit a doctor?

Nope. You don't need a doctor's visit to get a test with us.

You'll get your results via email as soon as they are available. We will notify you via SMS as well. You can also see them at any time in the future right in your dashboard where you can easily share them with your professional and compare them side by side with future tests.

Does my lab prescription expire?

Your order itself never expires.
