Gamma-Glutamyl Transferase (GGT) Testing
How to check your Gamma-Glutamyl Transferase levels with a home fingerprick blood test kit
What Is A Gamma-Glutamyl Transferase Test For?
The Gamma-Glutamyl Transferase (GGT) Test allows you to accurately check your levels of Gamma-Glutamyl Transferase in a fingerprick blood sample.
The enzyme Gamma-Glutamyl Transferase (GGT) is found throughout the body, but it is most concentrated in your liver.
This makes a GGT blood test very useful helping to assess liver function and general health.
GGT levels are usually low, but can rise following liver damage. A GGT test is also particularly sensitive to detecting bile duct problems.
What If Gamma-Glutamyl Transferase Test Levels Are High?
High levels of Gamma-Glutamyl Transpeptidase are found in people who drink a lot of alcohol or take a lot of other toxins (such as paracetamol).
This often indicates long-term liver damage and/or alcoholism. However, this damage can often be undone by adopting a healthier alcohol or toxin-free lifestyle.
Raised GGT concentrations indicate that something is going on with your liver but not specifically what.
Smoking may increase GGT concentrations and alcohol consumed within 24 hours of your GGT test may cause a temporary increase in the GGT result, if you consume alcohol regularly.
If this occurred you may want to repeat the test to verify the result.
Several drugs increase the concentration of GGT in the blood, including nonsteroidal anti-inflammatory drugs (NSAIDs), lipid-lowering drugs, antibiotics, histamine blockers, antifungal agents, anticonvulsants, antidepressants, and hormones such as testosterone. These increases do not indicate damage to the liver.
Otherwise, in general, the higher the result the greater the damage to your liver; these elevated concentrations may be due to liver disease or congestive heart failure.
If the GGT is very high, especially if other liver enzymes are also increased, then further investigation is needed to determine the cause.
What If Gamma-Glutamyl Transferase Test Levels Are Low?
Low or normal results are not usually of interest, but they do indicate that it is unlikely that you have liver disease.
