My ALT and AST fluctuated during treatment. The were still high at the end but were starting to come into line. my Dr was not worried about it, he said it was possible that it would fluctuate. I will be checking my LFT's in about a month to see where I am at.
I have not got mine back yet but they measure mine in 10 IU/ml to 50,000,000 anything under 10 is undetectable...
