Glutamyl transpeptidase is one of the indicators of liver function tests. It is mainly found in the hepatocyte plasma and intrahepatic bile duct epithelium, and the normal detection range is 0-40U/L. Above 60U/L indicates abnormality. Glutamyl transpeptidase is mildly elevated when it is 100U/L, and it can be normalized by active treatment. Elevated glutamyl transpeptidase is mostly seen in the following diseases, such as alcoholic fatty liver, non-alcoholic fatty liver, drug-related liver damage, acute and chronic viral hepatitis, hepatitis cirrhosis, primary biliary cholangitis, primary sclerosing cholangitis, etc. Elevated glutamyl transpeptidase can also be seen in tumors and extrahepatic obstruction. When glutamyl transpeptidase is elevated, the cause of its elevation needs to be clarified, and patients are suggested to go to the hospital to do hepatitis B and half, liver function, ultrasound and other tests to confirm the diagnosis. In daily life, it is recommended to abstain from alcohol and low-cholesterol diet; control weight, exercise reasonably and strengthen exercise, etc. If the index decreases after a period of time, there is no need for drug treatment; if the index continues to rise, you should follow the doctor’s advice and take appropriate drug treatment, and closely monitor glutamyl transpeptidase.
