The time it takes for transaminase 150 U/L to fall to normal is related to how early the cause is removed, with faster recovery after a period of active treatment. If the elevation is caused by drug factors, it will return to normal 2-3 days after stopping the drug. The standard for aminotransferase test is 40 U/L. When the aminotransferase is 150 U/L, it means that the aminotransferase has exceeded 3 times of the normal value. Generally speaking, more than 2 times of the normal value may be a pathological cause, which means that the liver has been damaged. At this point, if you want to bring the transaminases down to normal, you need to clarify the cause of the disease. If it is caused by fatty liver, you need to solve the problem of fatty liver; if it is caused by virus, you need antiviral treatment; if it is caused by drug factors, you need to remove the suspected drugs and carry out the corresponding treatment of liver protection and enzyme reduction. Therefore, transaminase 150 U/L needs to be removed from its etiology before it can be reduced to the normal reference range, and the length of time required during the treatment period is subject to individual variability, and no clear time frame can be given. In addition, for patients with high transaminases, it is necessary to promote the recovery of liver function by eating vitamin-rich vegetables and fruits, such as shiitake mushrooms and pears.
