The biggest benefit of autologous donation is that you’ll receive your own blood, and that it will be available if needed. There is also no risk of adverse reaction as a result of incompatibility or picking up possible donor infections.
On the downside, the donation process is rather time consuming and more costly due to the special collection, storage and testing requirements. The blood collected will also expire if your surgery is postponed. In addition, if you start bleeding unexpectedly during surgery, your surgeon might use general blood supply to supplement your own supply.
