The normal range of liver function alanine aminotransferase is 0-40μ/L, and the normal range of alanine aminotransferase is 0-37μ/L. The normal ratio of the two is 0.8-1.5, and the values will be different in different hospitals with different reagents, so it is recommended to take the examination in local hospitals as a reference. The ratio is not of clinical diagnostic significance when both AST and AST do not exceed the normal range. In the case of abnormal liver function, if the ratio of glutamic oxalate to glutamic acid is higher, it indicates more severe damage to liver cells, and if the ratio is lower, it indicates less severe damage to the liver. In addition, temporary high transaminases may also occur after overwork, strenuous exercise, consumption of greasy food and taking antibiotic drugs. If the patient develops uncomfortable symptoms, he/she should consult a doctor promptly.
