Glutamyl transpeptidase is generally referred to as gamma-glutamyl transpeptidase, and high levels of this enzyme are indicative of diseases of the hepatobiliary system, such as cholangitis, alcoholic liver disease, hepatitis, and other diseases. Glutamyl transpeptidase is widely found in human tissues, but most of the glutamyl transpeptidase in the serum comes from the liver, so abnormal glutamyl transpeptidase is often a reflection of problems in the liver system. Normal values of glutamyl transpeptidase are 11-50 U/L for men and 7-32 U/L for women. When glutamyl transpeptidase is greater than normal, it indicates diseases of the hepatobiliary system, such as alcoholic liver disease, primary liver cancer, hepatitis and cirrhosis, and fatty liver, etc. In addition, pancreatitis and pancreatic cancer are also common. In addition, pancreatitis, pancreatic cancer and other diseases can also lead to the increase of the index. If you have a high glutamyl transpeptidase index, you should go to the hospital in time, complete the relevant examinations to clarify the cause of the disease, and then take symptomatic treatment under the guidance of the doctor.
