The normal range of glutamine aminotransferase is 0~40 U/L. When the patient’s glutamine aminotransferase is 14 U/L, it belongs to the normal range, indicating that the patient’s liver function is not damaged at present. Glutamine aminotransferase is located in the liver cells and is usually found in very small amounts in the blood, but when the liver cells are severely damaged and liver function is impaired, it leads to rupture and damage of the liver cells, causing a large amount of glutamine aminotransferase to be released from the liver cells into the bloodstream, which results in a tendency for the glutamine aminotransferase to be elevated in the bloodstream. Currently, the patient’s alachlor aminotransferase of 14 is within the normal range, indicating that the patient’s liver function is currently normal, but certain liver diseases that are not preceded by liver damage may have normal liver enzymes, so the condition needs to be evaluated in conjunction with other laboratory tests as a whole. When the enzyme is normal, if there is no symptom and no liver disease, it can not be dealt with; if you have hepatitis, cirrhosis and other liver diseases, or nausea, loss of appetite, abdominal distension and other discomforts, consult a doctor in time, complete the relevant examination, clarify the cause of the disease, and actively treat it, so as to avoid delaying the condition.
