I just had had blood work done. Everything came out within the normal range except my AST levels were high. Granted, I partied too much, resulting in me drinking too much alcohol while in college, however, since the blood test, which was about a month ago, I have completely stayed away from alcohol and medication. I do not drink too much medication, only about once a month over the counter. Also, I recently heard that strenuous exercise will affect the AST levels to be elevated, and I do exercise on a regular basis. Unfortunately, I did not find out about the exercising until yesterday and I exercised the day before, which was the 6th. My next doctor appointment is on the 19th and I am supposed to have new blood work done a week before, which would be the 12th, making it six days after exercise. I tried new exercises, which resulted in my muscles being sore. So, my question is, how many days before the blood test should I not exercise? Should I postpone my appointments for another week

Liver Disorders, Hepatitis A,B,C Answer A21725
Hello and thank you for posting your medical question on E health forum.

Aspartate aminotransferase (AST) – an enzyme found in the liver and a few other places, particularly the heart and other muscles in the body.

The normal referance range of AST is 7-27 units/ L.

The increase in AST after exercise depends on the severity post workouts. A exercise routine that causes severe muscle soreness, pain and fatigue results in moderate elevation of enzyme levels. And the return of the levels to normal depend on the rate at which the muscles recover. Usually adequate rest and hydration will help muscle recovery within 2-3 days (Post severe muscle soreness).

Hence after this duration of 4-5 days the muscle enzyme levels might be normal.

I hope this helps.
