Gamma-glutamyltransferase 88 U/L is slightly above normal and may not be clinically significant. If it is significantly high, it may be related to liver disease, biliary tract obstruction, etc. The normal reference value of γ-glutamyltransferase for men is 10-60 U/L; for women, it is 7-45 U/L. Therefore, γ-glutamyltransferase 88 U/L is slightly higher than normal, which is generally of no clinical significance. When γ-glutamyltransferase is obviously high, it may be related to acute and chronic hepatitis, alcoholic hepatitis, drug hepatitis and other liver diseases; sclerosing cholangitis and other biliary tract obstruction can also cause γ-glutamyltransferase elevation. When the body γ-glutamyltransferase is high, the cause should be clarified under the guidance of the doctor in order to actively treat.
