In general, glutamyl transpeptidase 69 U/L is higher than the normal reference value, but not very high. Glutamyl transpeptidase, or gamma glutamyl transpeptidase, is widely distributed in human tissues, and gamma glutamyl transpeptidase in normal human serum mainly comes from the liver, with a normal reference range of 3 to 50 U/L (the reference range may vary under different measurement methods, subject to the local hospital). Serum γglutamyl transpeptidase is only mildly increased in acute hepatitis, chronic active hepatitis and decompensated cirrhosis; when obstructive jaundice, γglutamyl transpeptidase can be refluxed into the blood due to the excretion obstacle, causing a significant increase in serum γglutamyl transpeptidase; in primary hepatocellular carcinoma, the synthesis of γglutamyl transpeptidase in the liver is hyperactive, resulting in a significant increase in serum γglutamyl transpeptidase. It is recommended to consult a doctor in time to make a clear diagnosis of increased serum gamma glutamyl transpeptidase, and carry out targeted treatment under the guidance of the doctor.
