Glutamyltransferase 200, the normal value is 0-40 U/L, elevated about five times, is more serious. 1. Glutamyltransferase is an indicator of inflammatory damage to hepatocytes. When inflammatory damage is mild, only ghrelin and ghrelin are elevated, and transketolase is normal; when inflammatory damage is more pronounced, transketolase is elevated along with transketolase and the magnitude of transketolase is small, for example, when ghrelin is elevated by a factor of 10, transketolase is elevated by a factor of 2 or 3. 2. Transpeptidase is the most sensitive serum enzyme for cholestasis, and in inflammatory injury of the bile ducts and gallbladder, transpeptidase increases more than aminotransferase. In the recovery period of acute hepatitis, transaminase has been normalized, if transaminase continues to rise, it suggests that hepatitis is chronic; in chronic hepatitis, even if transaminase is normalized, after the exclusion of bile duct disease, transaminase increase indicates that the lesion is still active. 3. Transpeptidase also reflects liver fibrosis, when there is obvious fibrosis, transpeptidase will be higher than ghrelin; in cirrhosis with inactive inflammation, ghrelin may be normal but transpeptidase will be elevated; most of the cirrhosis is “small triple positive”, HBV DNA is very low or undetectable, but only transpeptidase is elevated, and transpeptidase is a marker of cirrhosis. Transpeptidase is the hallmark of cirrhosis. It is recommended that patients with elevated glutamyl transpeptidase should go to regular hospitals for timely consultation to avoid delay in diagnosis and treatment.
