In general, a little bit of low glutamyltransferase is not too serious and mostly suggests malnutrition. In the case of hepatitis patients, it may indicate severe hepatitis, which is more serious. Glutamyltransferase is mainly found in cell membranes and mitochondria, and helps liver cells to complete the metabolism of various substances inside and outside the body by participating in the metabolism of glutathione. Most of the glutamyl transferase in the serum comes from the hepatobiliary system. The normal value of glutamyltransferase is 10-60 U/L for men and 7-45 U/L for women, which is lower than the normal value for ordinary people, suggesting malnutrition, and the situation is not too serious, so it is usually enough to pay attention to observation and strengthen nutrition. However, for patients with hepatitis, a low indicator may indicate severe hepatitis, which is serious and needs to be dealt with as soon as possible. If the situation of low glutamyltransferase, you should go to the hospital in time to improve the relevant examination, under the guidance of the doctor symptomatic treatment.
