About the Gamma Glutamyl Transferase GGT Blood Test

Gamma Glutamyl Transferase (GGT) is an enzyme that plays a pivotal role in amino acid transport and is primarily found in the liver. It is also present in smaller amounts in the kidneys, pancreas, and spleen. Elevated levels of GGT in the bloodstream can serve as an early warning sign for a range of liver-related conditions, including liver damage, bile duct obstructions, and even chronic alcohol abuse.

By measuring the levels of GGT in your blood, this test provides a comprehensive overview of your liver`s current state. It is an essential asset for anyone looking to take timely intervention measures, effectively manage potential liver issues, or simply gain a deeper understanding of their liver health.

Whether you are concerned about the long-term effects of medication on your liver, have a family history of liver disease, or are experiencing symptoms that could be liver-related, our GGT Blood Test offers the vital insights you need to make informed decisions about your health.

Most of the biomarkers we offer in the "ready made" panels are also available separately. So if your favourite test panel is missing a biomarker you would like to have, no problem, you can add whatever you need to one of our standard panels using the "Pick-n-mix" options, such as this one.


    For most biomarkers our usual turnaround time is 24-48 hours, or less, from the time your sample is in our lab. We do not wait for all the results to complete before sending them to you, so you may start receiving results the same day for most cases, or as results become available.

    We are extremely proud of our very short turnaround times and a very efficient laboratory processes. Whilst we accommodate the shortest of time scales, with some results available within hours, for this particular test the usual turnaround time is:

    1-2 days

Doctor's notes

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

The liver is a vital organ with a myriad of functions, from detoxifying the body to producing essential proteins. Gamma Glutamyl Transferase (GGT) serves as a key biomarker for liver health, and elevated levels can be indicative of liver damage, bile duct issues, or other liver-related conditions.

Being proactive about your health means staying ahead of potential issues before they escalate. The GGT Blood Test is an invaluable tool in this regard. It allows for early intervention, enabling you to take the necessary steps to manage or even reverse liver issues. This test is particularly beneficial for those who are at risk of liver conditions, whether due to lifestyle choices, medication, or family history.

Red flag symptoms for the Gamma Glutamyl Transferase (GGT) Blood Test

If you experience any of the following symptoms, consult your doctor immediately. Even if your GGT levels are within the normal range, these symptoms could indicate an underlying liver or bile duct condition that requires further medical evaluation:

  • Jaundice (yellowing of the skin and eyes)
  • Persistent fatigue or weakness
  • Abdominal pain or discomfort, especially in the upper right side
  • Unexplained weight loss
  • Dark urine or pale-coloured stools
  • Nausea, vomiting, or loss of appetite
  • Swelling in the abdomen or legs

Special instructions

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Gamma Glutamyl Transferase (GGT) Blood Test.

Levels of GGT tend to decrease post-meal, so it’s advisable to fast for a minimum of eight hours before taking the test, consuming only water. 

Additionally, you should abstain from alcohol and discontinue specific prescription medications prior to the test. Some medications, like the anti-seizure drugs phenytoin and phenobarbital, can raise your GGT levels.

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit for Gamma Glutamyl Transferase (GGT) Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!
