Glutamyltransferase is a catalytic enzyme that is abundant in the kidney, liver and pancreas. The normal reference values are 11-50 U/L for men and 7-32 U/L for women. Clinically, low glutamyl transferase is not common and is usually normal at this time, indicating normal liver function and no need to worry excessively. At this time, it is enough to maintain a healthy diet, avoid staying up late, and avoid drinking large amounts of alcohol, which can damage liver function and lead to abnormal glutamyl transferase. Glutamyl transferase is mainly distributed in the liver, kidney, pancreas and other substantial organs, but the glutamyl transferase in the serum mainly comes from the hepatobiliary system. Testing for glutamyl transferase can be used for the diagnosis of intrahepatic excretory disorders, extrahepatic obstruction, cirrhosis, and to observe the process of alcoholic liver damage, and is widely used clinically. If a patient has hepatobiliary disease, or acute pancreatitis, congestive heart failure, myocardial infarction and diabetes mellitus, the test can be performed according to medical advice. If you are worried about the effect of low glutamyl transferase on your body, it is recommended that you have a physical examination on time. You can effectively understand your health condition and control it in time when it appears to be elevated.
