Clinically, there are three main enzymatic tests in liver function: glutamyl transferase, also known as glutamyl transferase, and two other essential ones, glutamyl transaminase and glutamic oxalacetic transaminase. There are many causes of elevated glutamyl transferase. 1. The most common cause of elevated glutamyl transferase alone is alcoholic hepatitis, and individual elevation is very obvious. Long-term heavy drinking, alcohol and its metabolite acetaldehyde, target damage mainly to intrahepatic capillary bile ducts and intrahepatic bile duct epithelial cells, and glutamyl transferase exists mainly in this place precisely. 2. If elevated glutamyl transferase is accompanied by If elevated glutamyl transferase is accompanied by elevated glutathione and glutathione, it is common in hepatitis, cirrhosis, liver cancer and so on. Of course, there are more reasons for elevated glutamyl transferase, so it is recommended to visit a professional medical institution to investigate the causes of the elevation and treat it in time.
