If the laboratory liver function glutamyl transpeptidase is elevated, it is most commonly associated with drug-induced hepatitis, alcoholic hepatitis, space-occupying lesions of the liver, or gallbladder disease. So it is important to clarify if there is a history of prolonged heavy alcohol consumption and if there are any medications or supplements that have been taken recently. Liver and gallbladder ultrasound should also be done to see if there are any space-occupying lesions in the liver, and if necessary, alpha-fetoprotein can be tested, and CT as well as enhancement of the liver can be done. It is also necessary to clarify whether there is chronic cholecystitis, gallbladder polyps, gallbladder stones and other diseases or bile duct stones, only to clarify the cause of the disease can be symptomatic treatment. If the cause of the disease is not relieved, just using liver-protecting and enzyme-lowering drugs is not very effective, and the disease is prone to recurring episodes. Therefore, once the glutamyl transpeptidase is elevated, you can follow the above methods to diagnose the cause of the disease, and if necessary, you can also do a liver puncture test.
