question: My ALT is 48 and the range is supposed to be 5-33; my ast is 37 and the range is listed as less than 32. I injured my back last december, and have been taking tylenol ever since. My dr. said ad long as i stayed under 3000 mg per day i was fine. I hesitate to take ibuprofen or other nsaids, as i was in the hospital for 5 days in march with low sodium. My numbers were all over the place especially those for kidney function. They thought the ibuprofen i was also taking at the time had caused this and said to be careful about any nsaids. So should i be concerned about my alt and ast?
