Purpose of the GGT Blood Test

A gamma-glutamyl transferase (GGT) blood test assesses liver health and detects liver, bile duct, and bone disease. In some cases, it is also used to monitor alcohol consumption as part of the rehabilitation or treatment for alcohol abuse.

What Does the GGT Test Measure?

The gamma GT test screens for gamma-glutamyl transferase – a type of enzyme that could suggest liver problems if found in high amounts.

An elevated GGT alone may not be enough to diagnose liver problems, as it could also be caused by problems in the bile duct and bone disease. Therefore, additional lab tests, like the bilirubin testalbumin blood test, and other liver function tests, might be requested by your healthcare provider.

Who Should Take a GGT Lab Test?

People who are obese, have type 2 diabetes, and drink alcohol heavily, should consider taking a GGT blood test as part of their annual checkup.

Liver problems don’t often show early signs and can only be detected through regular checkups and testing before developing complications. For this reason, it is typically run as part or along with the hepatic function panel.

On the other hand, your doctor will most likely order the test if you observe symptoms of liver problems such as the following.

  • Yellowing of the skin and eyes (jaundice)
  • Swollen and painful abdomen
  • Itchy and easily bruised skin
  • Swollen legs and ankle
  • Nausea or vomiting
  • Poor appetite
  • Dark urine
  • Pale stool
  • Fatigue

GGT Blood Work Preparation

As GGT drops after a meal, you must fast eight hours before your blood sample collection to ensure accurate test results. Likewise, you may be asked to avoid alcohol and skip certain prescriptions within the said timeframe.

GGT Test Results

The test value for GGT should not exceed 65 IU/L for males and 60 IU/L for females. Otherwise, it is considered abnormal.

An increased gamma-glutamyl transferase suggests liver problems linked to chronic illnesses such as liver disease, hepatic cancer, and cholestasis during pregnancy.

To further assess your liver function, your doctor may run other tests, such as alkaline phosphatase (ALP)alanine aminotransferase (ALT), and aspartate aminotransferase (AST) blood tests.
