Glutamyltransferase 150 U/L means that the result is elevated. If it is caused by physiological reasons, it is not serious, if it is caused by pathological reasons, it is more serious. 1. Physiological causes: Glutamyltransferase is one of the indicators of liver function, mainly found in the kidneys, liver, gallbladder, pancreas and other parts of the body. The normal reference range of glutamyltransferase for men is 10 to 60 U/L for men and 7 to 45 U/L for women, and the results may vary with different instruments. When there are triggers such as drinking, staying up late, exertion, huge mood swings, etc., it may lead to glutamyl transferase 150U/L. It is considered to be caused by physiological factors, and can usually return to normal after removing the triggers, so it is not serious. 2. Pathological causes: Glutamyl transferase 150U/L may be caused by intrahepatic bile duct obstruction, viral hepatitis, alcoholic hepatitis, pancreatitis, cirrhosis and other diseases that cause liver dysfunction. Regardless of the disease, it is considered more serious. In case of glutamyl transferase 150U/L, it is recommended to go to the hospital for further examination of abdominal ultrasound, blood and urine amylase to find the cause.
