Aminotransferase 143U/L one day down to 40U/L should continue to monitor liver function, and under the guidance of the doctor for liver protection therapy, and identify the cause of the disease. Liver function tests mainly reflect whether the liver is damaged or not, among which the most common transaminases are alanine transaminase and glutamic oxalate transaminase, with normal values of 0-40 U/L. When the transaminase is 143 U/L, it indicates that there is inflammation in the liver. A drop to 40U/L after one day indicates that liver damage may be reduced, and also needs to be evaluated in combination with other indicators of liver function. If there is a separation of bile enzymes, it is not an improvement but a sign of worsening liver disease. There are many reasons for elevated aminotransferases, such as viral hepatitis, drug hepatitis, alcoholic hepatitis, etc. It is recommended that the cause of the disease be clarified and then treated accordingly, and to avoid late nights, exertion, and alcohol consumption during the treatment period.
