this could be recurrent HCV, which would not be too unusual to recur. You may need to have a liver biopsy to definitely diagnose--there are wonderful new treatments for HCV that will be available soon.
Dear Friend:
You should ask your doctor. Sorry, but I do not know. Sometimes there is a brief anomaly with the post-transplant chemistry that passes on its own. Where did you get your transplant?
Hang in there! God bless you!
Yours,
