Glutamyl transpeptidase is clinically known as γ-glutamyltransferase. Whether 85U/L is serious needs to be analyzed in relation to the specific cause. If it is caused by non-disease factors, such as alcohol and drugs, it is generally not serious; if it is caused by diseases, such as acute and chronic viral hepatitis, it is generally more serious. Serum gamma-glutamyl transferase mainly comes from the hepatobiliary system, and the normal value is 11~50U/L for men and 7~32U/L for women. 1. Non-disease factors: common non-disease factors include taking certain liver drugs, drinking alcohol, etc., which are generally not serious, and γ-glutamyltransferase can be reduced to normal after discontinuing the use of drugs or quitting drinking. 2. Disease factors: a variety of diseases can cause γ-glutamyltransferase elevation, such as acute and chronic viral hepatitis, biliary tract obstructive disease, fatty liver, pancreatitis, etc., γ-glutamyltransferase elevation indicates that the liver function has been damaged, generally more serious, and need to be actively diagnosed and treated. When γ-glutamyltransferase is elevated, it is recommended to consult a doctor in a timely manner to clarify the cause under the guidance of a professional physician and follow the doctor’s instructions to standardize the treatment, so as not to delay the condition.
