I don't even have to have a biopsy. I was passed along to a gastoenterologist when my liver enzymes were getting high. Along with repeating the tests (test levels have come down a bit since) and doing additional testing for auto-immune problems, etc. and a liver ultrasound, all the tests came back NEGATIVE. My family doc is to repeat the enzymes tests on a regular basis to monitor the situation, but I've been cleared for having to worry about this in the present. Hurray!
