I do not believe the would do a liver biopsy in order for you to take Methotrexate. You would only do that test if you were having liver problems. Maybe you should try switching to 6mp. It is similar to Imuran but breaks down differently. I found much less side effects on 6mp than I did with Imuran. Good luck!
