Hi Adam, Doctors usually don't get alarmed at elevated liver enzymes until they are about double the upper limits of normal. As your ALT is around this point, I'd say this is something you need to work on.
No need to panic... They're not alarmingly high, but I wouldn't want to simply leave this as "not so bad" and forget about it for another year. You should be re-tested every 90 days as you work on why this might be going on.
Short term, this is not a problem, but I wouldn't want to spend the rest of my life at these levels. Keep working on this until you find the answer.
