A gamma-glutamyl transferase (GGT) test is a test to look for GGT in your child's blood. GGT is a protein (enzyme) that speeds up chemical reactions in the body. It's found mainly in the liver and the bile ducts. It's also called gamma-glutamyl transpeptidase.
The test is done to check for liver disease and bile duct blockage in children. It's also done when a child may have swallowed drugs or alcohol. The GGT test is usually done along with other tests, such as alanine aminotransferase (ALT).
In general, you don't need to prepare before your child has this test. The doctor may give you some specific instructions.
A health professional takes a sample of your child's blood.
The test will take a few minutes.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. Ask your doctor when you can expect to have your child's test results.
