Glutamyl transpeptidase 156 U/L is usually more serious and has exceeded 3 times the upper limit of the normal value, which means there is liver damage. Glutamyl transpeptidase is one of the more common liver biochemical indexes, and the normal value range is usually 0-40 U/L. If the test result is 156 U/L, which is more than 3 times the upper limit of the normal value, it is a significant increase, which indicates that there is a liver function damage. Significant elevation of glutamyl transpeptidase is mostly associated with hepatobiliary diseases, such as hepatitis, cirrhosis, hepatocellular carcinoma, cholecystitis, cholangiocarcinoma, etc., all of which may cause liver damage, which in turn leads to significant elevation of glutamyl transpeptidase. It is also necessary to clarify whether there are pharmacologic and autoimmune factors such as liver injury. If the test result of glutamyl transpeptidase is abnormal, it is recommended to go to the regular hospital for consultation, after clarifying the cause of the disease, and then carry out targeted treatment or therapy under the guidance of the doctor.
