Normal values for glutamyl transpeptidase are 0-50 U/L for men and 0-45 U/L for women; a glutamyl transpeptidase value of 120 is abnormal. Glutamyl transpeptidase is found in organs and tissues such as the kidneys, pancreas, liver, heart muscle, and skeletal muscle. Liver function can be determined by this enzyme if it is released into the bloodstream when liver cells are destroyed. If this indicator is greater than normal, it suggests liver function damage. For example, hepatitis, cirrhosis, cholecystitis, fatty liver, alcoholic liver and so on. Hepatitis B five, liver and gallbladder ultrasound and other tests can be further clarified. If it is caused by hepatitis B, liver protection tablets, diammonium glycyrrhizinate and other drugs can be given to reduce the index, and at the same time, entecavir, adefovir and other antiviral treatment can be given. The rise of glutamyl transpeptidase can also be caused by exertion, staying up late, drinking alcohol, drugs, stimulating food, etc., but it is generally lower than three times of the normal value, and dietary modification is the main focus of life. If glutamyl transpeptidase is elevated, it is recommended to consult a doctor to analyze and formulate treatment measures.
