Glutamate aminotransferase is short for aspartate aminotransferase, abbreviated as AST, which comes from muscle tissue, such as skeletal muscle or heart muscle, and can also come from the liver, and is generally used as an auxiliary test for myocardial infarction and myocarditis and as an indicator when liver cells are damaged. The normal range of glutamic aminotransferase is 0-40U/L, so 14U/L indicates a normal examination and generally has no clinical significance. Only when it exceeds 40U/ is liver function considered abnormal, such as acute and chronic hepatitis, viral hepatitis, drug-related liver damage, alcoholic liver disease and cirrhosis, etc., it can be elevated. When there is a long-term lack of exercise and the metabolic state of the body is relatively low, a glutathione level of 14U/L may occur. This can also occur after eating large amounts of spicy and irritating foods, fried and greasy foods. Patients are usually advised to take rest, not to eat spicy and stimulating food, avoid smoking and alcohol, not to eat fried food, eat more vegetables and fruits, keep a relaxed mood, not to stay up late and not to overexert themselves. Outdoor aerobic exercises, such as hiking, jogging, swimming and tai chi, are good for the health of the body. If there are uncomfortable symptoms should be regularly checked liver function, hepatitis B five and liver ultrasound, testing indicators within the normal range of up and down, usually no clinical significance.
