Gamma GT this test is also known as GGT and GTPtest.  The test is for detecting liver problems. This test measures the GGT enzyme in the blood. GGT Test used to find the damage in bile ducts and assessment of liver function.


High levels are markers of oxidative stress, resulting from factors like heavy metals, cardiovascular diseases, and diabetes. When the liver is damaged due to infections like in the case of viral hepatitis, this enzyme leaks into the bloodstream, hence high levels of GTT may be an indication of liver disease e.g. fatty liver (NAFLD-Non-alcoholic fatty liver disease) or damage to the bile ducts due to gall stones (bile ducts are tubes that carry bile in and out of liver).  Hence, usually, this test is suggested in cases suspected of any damage to the liver (in chronic alcoholics) or bile ducts (cases with obstructive jaundice) and also in cases such as certain bone diseases. Other associated tests include an enzymatic method, kit method, colorimetric methods, spectrometric methods, etc.
