HELP - PLEASE

I am having surgery on Friday and I have been reading people's story's and I noticed that a lot of people had to do last minute bloodwork from the hospital. My hospital hasn't requested anything. Should I be concerned. I don't want this to get rescheduled.

My surgeon gave me an order to take to the hospital a week before and have it drawn. You might want to call them in the morning and ask. Good luck!!!! Katie
