Glutamyltransferase 82U/L is a mild increase, which is not serious if it is physiologic, but more serious if it is pathologic, which may indicate that the patient has liver disease and needs timely treatment. The normal range of glutamyltransferase is 5~54U/L. Glutamyltransferase 82U/L exceeding the normal range is a mild increase, which may be caused by improper diet, for example, eating too much high-protein food, resulting in increased burden on the liver, thus causing the glutamyltransferase to rise, which is not serious, and can be restored to normal after controlling the diet and reducing the amount of high-protein food. In addition, elevated glutamyl transferase can also be caused by liver diseases, such as viral hepatitis or cirrhosis, which are often more serious, especially cirrhosis, and require timely treatment, otherwise the disease will continue to progress. Glutamyltransferase 82U/L must be consulted in time to identify the cause and avoid delay in treatment.
