GGT (Gamma GT) test at home in Dubai
GGT is one of the most sensitive liver enzymes. It often rises with regular drinking or fatty liver well before other liver markers move.
What the test measures
Gamma GT (Gamma-Glutamyl Transferase). An enzyme found mainly in the liver and bile ducts, which rises with alcohol, fatty liver, some medicines and problems with bile flow.
ALP on the same draw. Read together, GGT and ALP help show whether a raised ALP is coming from the liver or from bone.
Who should test
GGT is very sensitive but not very specific. It rises quickly with regular alcohol, including a heavy weekend, and falls again over a few weeks when drinking stops. It also rises with fatty liver, extra weight around the middle, raised blood sugar and some long-term medicines. That makes it a useful early signal of a liver under load, even when ALT and AST are still in range.
GGT also has a second job. ALP, another liver enzyme, can come from bone as well as the liver. If ALP is raised and GGT is normal, bone is the more likely source. If both are raised, the liver or bile ducts are more likely. Raised GGT is also linked in studies with higher cardiometabolic risk, so it is read alongside the lipid and diabetes markers on the same screen.
- Regular alcohol, including weekend drinking
- Extra weight around the middle, or raised blood sugar
- Long-term medicine, such as some epilepsy medicines
- A raised ALP on a previous test
- Wanting to see the effect of cutting back on alcohol
How to prepare
- Follow the fasting instructions for the full screen: an overnight fast with water only.
- Avoid alcohol for at least 24-48 hours, and be honest at your review about usual intake, since GGT reflects weeks of drinking, not one night.
- Keep a list of medicines and supplements to share at your review.
Reading your results
Units and ranges
GGT is reported in units per litre (U/L). Ranges are usually higher for men than for women and vary by lab, so the result is read against the lab's own range.
If it comes back high
A raised GGT is most often linked with alcohol, fatty liver or some medicines. It often falls within weeks of cutting back on alcohol, which a recheck can show. A high GGT with a raised ALP or bilirubin can point to a bile flow problem and should be followed up with your own doctor.
If it comes back low
A low GGT is not a concern. It simply means this enzyme is not raised.
Reference ranges differ between labs, and a single result is a snapshot. Your consultant reads every value against your history and the rest of the screen, not in isolation.
How the home test works
This test is part of Baseline’s full blood screen: 122 parameters across ten systems from one draw, for AED 850, with results in 48 hours. It is not sold as a single test, because the result means more next to everything else.
- Nurse comes to you. A licensed phlebotomist visits your home or office, 7 days a week, anywhere in the UAE.
- Accredited lab. Samples are processed by a CAP-accredited laboratory (College of American Pathologists), also accredited to ISO 15189, against clinical reference ranges.
- Reviewed with you. Results land in your account in Baseline format, and your consultant walks you through them on video, never a PDF dumped in your inbox.
Ranges are the lab’s own. Your consultant goes through what they mean with you.
Your results arrive in the Baseline app, every marker against the lab’s own range, checked by your consultant before you see them. The values above are an example.
Questions
- Does one night of drinking raise GGT?
- A single drink usually has little effect. GGT mostly reflects regular drinking over the previous weeks, though a heavy weekend can push it up. Avoiding alcohol for 24-48 hours before the draw is still sensible.
- How quickly does GGT come down after stopping alcohol?
- It often falls noticeably within a few weeks and can return to range within a couple of months, depending on how high it was and whether other causes such as fatty liver are involved.
- Can GGT be high if I do not drink?
- Yes. Fatty liver, extra weight, raised blood sugar, some medicines and bile duct problems can all raise GGT in people who do not drink at all.
- Can I book a GGT test on its own?
- No. Gamma GT is one of 122 parameters in the full home screen, measured from the same single draw as everything else.
