Sorry bro but you are kidding right? 24 hrs to correct blood test probs......................Not going to happen. The only thing that will change in that time is blood glucose!!
I assume (or at least I hope LOL) they would tell you themselves if something was that wrong that it might cause problems. It's good you're trying to look out for yourself but the people working on you should be trained better than you are, so don't overanalyze and relax. Just enjoy the anesthesia!
