GGT is one of the liver enzymes that are usually restricted to the areas of the liver and some other organs but when there is some kind of liver disease, the levels of this enzyme increase because the enzyme starts to leak out of the liver into the bloodstream.levated GGT levels themselves do not mean anything as the levels of GGT tend to fluctuate during the day; however, the presence of jaundice is usually confirmation enough of some kind of liver damage. A GGT test should then be compared with an ALP test.
