The normal range of glutamyl transpeptidase is usually 5-40 U/L, and the result of 160 U/L is an elevated value. Whether it is serious or not needs to be judged in conjunction with the general condition and medical history. If it is caused by medication or staying up late, it is usually not serious; if it is caused by disease, it is serious. 1. Caused by drugs or staying up all night: If taking drugs such as phenobarbital or ethanol, or if the patient stays up all night for a long period of time, the value of glutamyl transpeptidase may be elevated. Generally, by adjusting the correct lifestyle, choosing a light and easy-to-digest diet, maintaining sufficient sleep, stopping or reducing medication as prescribed by the doctor, and regular review, it can be restored to normal for a period of time. 3. Disease-induced: If the patient has hepatitis, fatty liver and other diseases, the value of glutamyl transpeptidase increases, suggesting that there is a certain degree of damage to the liver cells, so that the body’s glutamyl transpeptidase content increases, and then the condition is relatively serious, and requires timely treatment. Patients with high glutamyl transpeptidase should go to the hospital in time to clarify the cause of the disease, symptomatic treatment, so as not to cause adverse consequences.
