γ-Glutamyltransferase 170 is significantly higher than the normal value, suggesting hepatocellular damage or biliary tract disease, etc. It should be judged in conjunction with the condition of the disease and accompanying symptoms, and cannot directly say whether it is serious or not. γ-Glutamyltransferase is an enzyme that catalyzes reactions in the liver, and its normal value is 0-40 U/L. If there is damage to liver cells due to hepatitis or cirrhosis, or if there are diseases such as cholecystitis or gallstones, γ-Glutamyltransferase will be elevated. Gamma-glutamyltransferase 170 U/L, significantly higher than the normal value, generally suggests that there is hepatocellular damage, or biliary tract diseases. It is necessary to combine the patient’s specific clinical symptoms and other indicators to comprehensively determine whether it is serious. When this phenomenon occurs, the cause should be promptly identified under the guidance of the doctor, and timely treatment. Usually pay attention to a light diet, avoid drinking alcohol.
