Gamma-GT (Gamma-Glutamyltransferase) is an enzyme primarily present in the liver. It plays a role in the metabolism of amino acids, the building blocks of proteins.
Testing Gamma-GT can be useful for assessing liver health and for detecting liver diseases, such as hepatitis or cirrhosis. It can also assist in detecting alcohol misuse or exposure to hepatotoxic medications or substances.
A Gamma-GT test is used to check for signs of liver damage or disease. It helps identify blockages in the bile ducts and can be used as part of the evaluation of certain liver diseases.
A high level of Gamma-GT in the blood may indicate liver damage or disease. It can also be associated with excessive alcohol consumption, the use of certain medications, or exposure to hepatotoxic substances.
Low levels of Gamma-GT are generally not cause for concern and are rarely considered clinically significant. However, extremely low levels may, in rare cases, indicate reduced liver function.
Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
