If I have hepatitis C, wouldn’t my ALT levels automatically high and mess my labs up?

I’m currently on methadone & have hepatitis C. While it doesn’t seem the methadone is an issue, i was originally approved by my surgeon and then brought it back up to reassure a getting closer to my surgery date. Basically, I’m just concerned that due to having hepatitis C, my ALT levels will automatically be high & make me not a candidate anymore and cause issues. Is that typically an issue if they know why the levels are high???
