I am 30 m 170lb. i just got my liver functions tested. my alt came out 51 and asa came out 38. is it normal or my levels are high?

That's high: You'll need to find the cause. Probably these will be rechecked off alcohol and meds (even iboprofen can do this). We'll want to rule out hepatitis b and c, hemochromatosis, wilson's, autoimmune hepatitis and a few others. If all are ruled out, this may just be your liver's way of telling you that it wants you to back to that intensive physical training you loved doing as a teen.
