About this test

GGT is a gamma-glutamyl transferase, an enzyme bound to cell membranes with the highest concentration in the liver. It is very sensitive to changes in liver function, but also to damage to the biliary tract (for example, as a result of drug or alcohol damage).

Benefits of GGT blood test 

  • Results within 1 working day 
  • During a single blood draw, we can analyse this parameter along with a range of additional biomarkers. Explore our Product Configurator.
  • Part of more than 10 examinations (e.g. Female Prevention or Male Prevention) 
  • Very sensitive to changes in liver function and to damage to the bile ducts, for example due to medication or alcohol use 
  • GGT (gamma-glutamyltransferase) is an enzyme bound to cell membranes, mainly found in the liver 

Notice

Laboratory test results must always be interpreted in the context of the patient’s medical history, clinical condition, and the results of other laboratory and diagnostic tests. Deviations from normal values are not sufficient on their own to establish a diagnosis, and values within the normal range do not always mean that a disease is absent. It is advisable to consult a doctor about the results.

Collection instructions

Please read these instructions carefully well in advance of the collection.

Please bring a valid ID (ID card or passport) to verify your identity.

What interests you about the GGT test?

What does elevated GGT mean?

A high level of GGT in the blood can be a sign of liver disease or damage to the bile ducts, specifically disorders of the outflow of bile into the liver, which is often associated with bile duct disease, acute and chronic liver disease, or liver and pancreatic tumors.

How to lower GGT levels in the blood?

If you need to lower your GGT levels, avoid alcohol, junk food, and smoking. Instead, include liver-friendly foods in your diet (vegetables, grains, beans, nuts), take liver-friendly supplements, and exercise moderately.

What increases GGT levels?

Excessive consumption of red meat, alcohol and certain medications (beware of phenobarbital, phenytoin, heparin or warfarin) drastically increases GGT levels, an enzyme located on the cell membrane with the highest concentration in the liver.

What does the abbreviation GGT mean?

GGT is gamma-glutamyltransferase is an enzyme located on the cell membrane with the highest concentration in the liver. It is very sensitive to changes in the bile ducts (for example, due to damage by drugs and especially alcohol).

How fast does GGT drop?

The speed at which your GGT levels drop depends on whether you conscientiously follow the rules that actually lead to a decrease. For example, if you give up alcohol, your GGT levels will drop significantly after just a month. However, gradual changes can be noticed in as little as two weeks, according to experts (1).
