Glutamine refers to the enzyme alanine aminotransferase as well as glutamine aminotransferase. Generally speaking, a low level of these two enzymes is not clinically significant and may be a normal physiological fluctuation, so there is no need to worry too much. Clinically, ALT and AST are commonly used to determine the function of the liver. When they are elevated, it indicates abnormal liver function, which may be due to viral hepatitis, alcoholic hepatitis, cirrhosis, liver cancer, and so on. However, low levels of ALT and AST have no direct clinical significance. If they are not accompanied by other abnormalities, there is no need for undue concern. When you find your alanine aminotransferase and glutamic aminotransferase results are low, you can consult your doctor in time, clarify the specific causes under the doctor’s guidance, and actively adjust your lifestyle to promote your health.
