There are many reasons for the elevation of γ-glutamyl transpeptidase GGT, including physiologic factors, such as intense exercise, uncontrolled diet, pregnancy, etc., and pathologic factors, such as hepatobiliary and pancreatic diseases, prostate tumors, pharmacologic factors, etc. The normal value of γ-glutamyl transpeptidase GGT is 0-50 U/L, and the achievement of 78 U/L is not serious, and belongs to the mild elevation, which indicates that the liver function may have acute or mild impairment. γ-Glutamyl transpeptidase is mainly produced through the liver, when the liver cells are damaged and liver function is destroyed, the rupture of liver cells leads to the release of γ-Glutamyl transpeptidase into the blood, and there is a tendency to elevate it, which is 0-50U under normal circumstances, and when the patient is 78U, it suggests that the mild elevation is not serious, and at this time, it is necessary to find out the cause of liver injury as soon as possible, and to carry out the corresponding treatment. It is also necessary to regularly monitor changes in γ-glutamyl transpeptidase, as well as glutamic and glutamic alanine transaminases, and when they both appear to be persistently and dramatically elevated, it is important to quickly complete other tests to avoid worsening liver injury.
