Thanks so much for the reply. I do have an MRCP scheduled for a week from Monday. My Gi wants me to do it since my ALT and AST have actually come down from where they have been before, even before MTX, but this last test my AP went up to 250 from 150. I had just got done a round of Biaxin for a sinus infection and I read that that can make enzyme levels wacky. I have no other symptoms, although they say that is normal too. I am just a bit freaked out cause it seems like such a sentence, but I guess it is an inexact science from what you are saying. Did you ever have a Biopsy? It's weird, at some checks my AP is normal and my others are muc close to 100, and this one is now completely different. My P-anka test was negative, so my Gi syas there is a 13% chance I could still have PSC. And he also says it could just be me. My enzyme levels long before I had UC were always a bit high, but GP always said that was just me. He checked me once a year since I was on lipitor. I went off of crestor before my last test and I am sure my Cholesterol is way up there...maybe I should go back on it since it seems to help the tryglycerides that can clog up in the liver. At this point I just don't know!...Thanks again for your support.
