Is it possible to give your own blood for future use? Can it be frozen? Is there an expiration date?
Yes, that is quite common. Before you go into a pre-planned surgery you can donate your own blood or the blood of a family member or match.
yes, ut it alsocis possible for them to not lose yur blood during an operation, but as they suction it away, they run it through a collector/repurifier - like dialysis - and give your own blood back to you. many hospitals can do this.
