To screen for liver disease or alcohol abuse; and to help your doctor tell whether a raised concentration of alkaline phosphatase (ALP) in the bloodstream is due to liver or bone disease
If your doctor thinks that you have symptoms of a liver disorder/disease
A blood sample taken from a vein in your arm

Gamma-glutamyl transferase (GGT) is an enzyme found mainly in the liver. When the liver is injured or the flow of bile is obstructed, the concentration of GGT within the bloodstream rises. It is therefore a useful marker for detecting bile duct problems.
How is the sample collected for testing?
A blood sample is obtained by inserting a needle into a vein in the arm.
Is any test preparation needed to ensure the quality of the sample?
