An excessive level of GGT can result from a number of different causes, so treatment varies with the cause. For example, patients who have been consuming too much alcohol may simply cut back or abstain from alcohol for a month or two before repeating the test, according to Healthline.Continue Reading
The GGT test measures the levels of the enzyme gamma-glutamyl transpeptidase in the bloodstream. The purpose of GGT is that of a transport molecule, facilitating the movement of other molecules. It helps the liver break down such toxins as drugs. It appears in the liver, spleen, kidneys, pancreas and gallbladder. When GGT levels are high, liver damage is frequently the cause, notes Healthline.
Many of the causes for elevated GGT levels go beyond excessive alcohol consumption. Hepatitis, cirrhosis, liver tumors, heart failure, abuse of drugs and insufficient blood flow to the liver may cause GGT levels to rise. When GGT is tested, it is measured in relation to alkaline phosphatase, which is another enzyme. When both enzymes are high, the likely reasons are problems with the bile ducts or the liver. When GGT is normal but ALP is high, bone disease could be the problem, reports Healthline. After the initial GGT test, the doctor performs additional tests to find the precise reason for elevated GGT and determine the appropriate treatment.Learn more about Medical Ranges & Levels
