many types of medications can cause it including tylenol and ibuprofen. make sure you havent taken these for long periods of time before you take the blood work. Also, milk thistle and liv52 can help bring your values lower. But I have the same problem. I just got blood work and my values are elevated. Ive never overdosed on orals and havent been on for months. I'll let you know if I figure out what was causing mine.
