When my husband had surgery, I looked into this. I was told by a donation center that the blood recipient needs a Dr's prescription. My 0- son would need to take the RX to the blood donation center to draw his blood. Due to testing and filtering, they need at least 3 days before surgery to get the blood ready. Now, trusting that THIS EXACT blood is received if necessary or not given/ used by someone else is a different story.
