The normal value of glutamyl transpeptidase for men is 11~50U/L, and for women is 7~32U/L. If it is 65U/L, it suggests liver function abnormality, and it is considered to be related to alcoholic liver disease, viral hepatitis, cirrhosis of the liver and pancreatitis. 1. Alcoholic liver disease: long-term alcohol consumption can cause damage to liver cells, affecting liver function and leading to elevated glutamyl transpeptidase. 2. Viral hepatitis: the most common ones are viral hepatitis B and viral hepatitis C. Viral infection can lead to liver cell damage and elevation of glutamyl transpeptidase. 3. Cirrhosis and pancreatitis: Cirrhosis and pancreatitis can lead to mild abnormalities in liver function. It is recommended to review liver function regularly, clarify the cause of the disease under the guidance of professional physicians, and carry out targeted treatment in a timely manner.
