I was diagnosed with Autoimmune Hepatitus a couple of months ago. I first found out in Dec of last year my GGT levels were up to 150. I had a liver biopsy back in April. I know I was tested for ANA and anti smooth muscle, but don't really know how high my levels were. I start medication at the end of the month. My doctor is putting me on Immuran and Predisone. Do you know any thing about these two meds?
