What is GAMMA-GT (GGT) + CDT?
GAMMA-GT (GGT) and Carbohydrate Deficient Transferrin (CDT) are biomarkers in the blood used to monitor alcohol consumption. GGT is an enzyme involved in the metabolism of fats and alcohol in the liver, while CDT is a form of transferrin, a protein that transports iron in the blood, which decreases with prolonged excessive alcohol use.
Why would you choose to test GAMMA-GT (GGT) + CDT?
This test is useful for people who want to monitor or evaluate their alcohol consumption, especially in situations where excessive use might pose a health risk. It is also helpful for medical professionals to detect and assess alcohol misuse, as well as for evaluating liver function.
What does it indicate?
An elevated level of GGT and/or CDT may indicate excessive alcohol consumption or liver damage. These tests provide an objective measurement to evaluate alcohol use and its effects on the liver.
What does a high GGT or CDT level mean?
A high level may indicate recent excessive alcohol use, liver inflammation, or damage caused by prolonged alcohol misuse. It may also indicate other liver conditions.
May sometimes be used by the CBR.
Frequently asked questions
Answers to what people usually want to know.
How does it work from order to result?
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.
How quickly can I get tested?
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.
Do I need to book an appointment?
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
