A high glutamyl transpeptidase of 200 indicates impaired liver function and gallbladder disease. Under normal circumstances, glutamyl aminotransferase does not appear high, but when the liver function is damaged, some of the glutamyl aminotransferase will enter the human blood circulation and can be found to be high during the examination, and the higher the degree of high, the more serious the liver function is damaged. The common liver diseases that lead to high glutamyl transpeptidase 200 include cirrhosis, viral hepatitis, severe fatty liver, primary liver cancer, and further liver function tests are needed to confirm the diagnosis, and the bile secreted by the liver is mainly stored in the gallbladder, which will discharge bile into the digestive system through contraction during diet. If there are diseases in the gallbladder, such as cholecystitis and gallstones, it will affect the bile excretion and cause some of the bile to enter the human blood circulation, and high glutamyl transpeptidase can be found during the examination.
