Hi, I recently performed a annual check up and got my results yesterday. Everything else is normal besides my liver enzymes. My AST is 86units(36 units above Quest Lab's upper end for normal range), My ALT is normal (50units)but close to the upper end of the normal range. I don't drink alchol at all and I did not take any anti-biotics recently. The only things abnormal before the test was I only slept for 4 hours the previous night because I have to finish a project. Also my knee was injured and got a bit inflammation at that time. I will go for a second test next week so I just want some info here. Does the lack of sleep and the knee injury contributed to my elvated AST? Thanks
