ALT and AST level elevated while on isotretinoin. Should I be worried?

I've been on isotretinoin for almost 2 months and my acne has cleared up significantly during this time. I just got my results of my second blood test though and my liver enzymes have drastically elevated - ALT 129 and AST 72. I'm seeing my doctor next week but till then, I'm wondering how worried I should be? Also, I had a terrible bout of stomach flu one week before my blood test. Would that have had affect?
