The gamma GT test is another term for the gamma-glutamyl transpeptidase (GTT) screening. Information technology is an extremely comprehensive examination that looks for liver office or potential liver disease. This test measures the claret level of GGT, a liver enzyme that serves a key office as a transport molecule, and helps the liver metabolize substances, such as drugs, alcohol, and toxins. Read on to learn nigh GGT, why the test is ordered, and what elevated levels may mean.

Why Is the GGT Test Ordered?

Unlike some other routine blood tests, the gamma GT test is ordered because your physician suspects liver disease . It is non function of a complete blood count (CBC) or other batteries of tests that check for overall health. The GGT test is the gold standard to measure out the enzyme function in the liver. It is oft ordered for those who suffer from booze use disorder (AUD), who may have washed damage to their liver. Yet, liver impairment can too exist caused by poisonous substance ingestion, drug abuse, and other diseases. All toxins must filter through the liver, and if there is an overabundance of toxins at a given time or over a period of time, the liver may incur impairment.

Westward hat Are the Symptoms of Liver Problems?

If your doctor has ordered a GGT exam, he or she either suspects liver issues, or you are presenting with symptoms that indicate a liver condition. Some common symptoms of liver problems include:

Night urine
Light-colored feces
Jaundice (yellowing of the peel and eyes)
Lethargy
Intestinal hurting
Nausea and/or vomiting
Lack of ambition
Itchy skin

It is true that many of these symptoms may exist indicative of other problems, such as gastrointestinal upset. Your doctor may desire to rule out a liver problem to find the correct diagnosis.

W hat Are Normal and High Gamma GT Levels?

Normal GGT levels fall between 0 and 30 international units per liter (IU/Fifty), for both children and adults, though these levels may be slightly higher in newborn infants. Levels of GGT tin as well vary depending on circumstances. If a person with alcohol use disorder has had a potable the night earlier the exam, the exam could exist wildly elevated. However, a person with AUD who has had even a curt catamenia of sobriety may have a normal level. Unless the liver is permanently damaged, as with cirrhosis (scarring of the liver), it is extremely elastic and tin "bounciness dorsum," even from loftier levels of GGT and moderate liver damage. If alcohol is the culprit, however, the person must maintain sobriety in society for the liver to recover. High GGT levels are any level above the 30 international units per liter mark.

West chapeau Are Other Causes of High GGT?

Booze abuse is most often the cause of high GGT levels, but at that place can be other reasons. High gamma GT levels may also be caused by hepatitis, liver tumor, cirrhosis of the liver, diabetes, pancreatitis, and nonalcoholic fatty liver disease (NAFLD). If your GGT level is high, your doc will probable want to society farther tests to check your liver.

Due west hat Other Tests Check Liver Operation?

A GGT test is the nearly comprehensive of the liver function tests. Even so, your physician may want to order other tests, or perform more invasive procedures, such as a liver biopsy. Other liver function tests include the alanine transaminase (ALT) examination, the aspartate aminotransferase (AST) exam, and the alkali metal phosphatase (ALP) test. These are all enzyme blood tests.

W lid Is the Outlook for Liver Disease?

With the exception of cirrhosis, which is irreversible, the outlook for liver illness as it relates to alcoholism or booze abuse is fairly positive , provided the patient stops drinking and maintains sobriety. The liver is a versatile organ, and tin easily revert back to its original functioning provided information technology is no longer having to filter high levels of toxins (such as alcohol). Liver disease with respect to alcohol for a patient who is unable to stop drinking has a poor prognosis. Many cases of liver disease will progress to cirrhosis, which is frequently terminal.
