A low aminotransferase ratio is usually normal, has no clinical significance, does not require special treatment, and needs to be reviewed periodically. If the aminotransferase ratio is high, it needs to be taken seriously. Transaminase is an indicator of liver function, and the ratio of transaminase refers to the ratio of alanine transaminase to alanine transaminase, and the normal range of alanine transaminase and alanine transaminase is 0~40 U/L. A low aminotransferase ratio that is within the normal range for both alanine and glutamine is generally normal and does not require special treatment. If the value of aminotransferase is high and the ratio is low, there may be liver cell damage caused by alcohol, drugs, etc., or heart or skeletal muscle damage, or it may be due to the application of enzyme-lowering drugs, such as polyene phosphatidylcholine capsules. It is necessary to go to the hospital for further examination to clarify the cause of the disease and timely treatment.
