The gamma GT test is another term for the gamma-glutamyl transpeptidase (GTT) screening. It is an extremely comprehensive test that looks for liver function or potential liver affliction. This exam measures the blood level of GGT, a liver enzyme that serves a fundamental role as a transport molecule, and helps the liver metabolize substances, such every bit drugs, alcohol, and toxins. Read on to learn about GGT, why the examination is ordered, and what elevated levels may mean.
Why Is the GGT Test Ordered?
Unlike some other routine claret tests, the gamma GT test is ordered because your medico
suspects liver disease. It is not function of a complete blood count (CBC) or other batteries of tests that check for overall health. The GGT test is the gilt standard to mensurate the enzyme part in the liver. Information technology is frequently ordered for those who suffer from alcohol apply disorder (AUD), who may have done damage to their liver. Yet, liver damage can also exist acquired by poison ingestion, drug abuse, and other diseases. All toxins must filter through the liver, and if in that location is an overabundance of toxins at a given time or over a period of time, the liver may incur damage.
hat Are the Symptoms of Liver Problems?
If your md has ordered a GGT examination, he or she either suspects liver problems, or yous are presenting with symptoms that bespeak a liver condition. Some common symptoms of liver problems include:
- Dark urine
- Calorie-free-colored feces
- Jaundice (yellowing of the skin and eyes)
- Abdominal pain
- Nausea and/or vomiting
- Lack of appetite
- Itchy peel
It is true that many of these symptoms may be indicative of other problems, such every bit gastrointestinal upset. Your doctor may want to rule out a liver problem to find the correct diagnosis.
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 also vary depending on circumstances. If a person with alcohol employ disorder has had a drink the night earlier the test, the exam could be wildly elevated. Still, a person with AUD who has had even a brusk period of sobriety may take a normal level. Unless the liver is permanently damaged, every bit with cirrhosis (scarring of the liver), information technology is extremely elastic and can “bounciness dorsum,” fifty-fifty from loftier levels of GGT and moderate liver damage. If booze is the culprit, all the same, the person must maintain sobriety in order for the liver to recover. High GGT levels are any level above the thirty international units per liter mark.
hat Are Other Causes of High GGT?
Alcohol corruption is most oftentimes the cause of high GGT levels, but in that location can exist other reasons. High gamma GT levels may also exist caused past hepatitis, liver tumor, cirrhosis of the liver, diabetes, pancreatitis, and nonalcoholic fat liver disease (NAFLD). If your GGT level is loftier, your doctor will likely want to social club further tests to check your liver.
chapeau Other Tests Check Liver Operation?
A GGT test is the most comprehensive of the liver function tests. Even so, your physician may desire to order other tests, or perform more invasive procedures, such every bit a liver biopsy. Other
liver function tests
include the alanine transaminase (ALT) test, the aspartate aminotransferase (AST) test, and the alkaline phosphatase (ALP) test. These are all enzyme blood tests.
hat 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
adequately positive, provided the patient stops drinking and maintains sobriety. The liver is a versatile organ, and tin easily revert back to its original operation provided it 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 volition progress to cirrhosis, which is oftentimes final.
