The reference value for transaminases is generally between 0 and 40 u/l, with transaminases 45 u/l considered mildly elevated. A transaminase value of 45 u/l is generally considered to be mildly elevated and higher than the normal transaminase value. An exponential increase in aminotransferases is generally indicative of a liver abnormality. Aminotransferases are found mainly in liver cells, and an abnormality can lead to damage to the liver cells, releasing aminotransferases, which can lead to an increase in aminotransferase levels in the blood. Transaminases 45u/l, need to adjust the diet, avoid alcohol, pay attention to rest, active treatment of the cause of the disease, regular and continuous testing of changes in transaminases, timely intervention to improve the corresponding risk factors. If the transaminase is abnormal, it is recommended to consult a doctor to clarify the cause of the disease in order to avoid delaying the condition.
