Autologous blood donation, in which you donate your own blood for use during a surgical procedure, was quite popular in the early 1980s when the risk of HIV infection was very real. But today it's not worth doing if your community has an adequate blood supply.
Although autologous donations can spare you some of the very low infectious risks of using the available blood supply, from a cost/benefit standpoint it's a very expensive option to prevent a very few bad outcomes. Experts note that the use of autologous donation to prevent virus transmission can cost hundreds of thousands of dollars, if not millions, per infection avoided.
Half of all autologous donor blood doesn't even get used, and must be discarded. Plus, even if you donate your own blood, you may still have a reaction during the transfusion. Or, your donation could get mixed up with someone else's and used for the wrong patient. A survey by the American Association of Blood Banks suggested that one percent of all autologous units may be transfused to the wrong person.
Overall, experts agree, the safest alternative for medically needed transfusion remains your own blood, but, in most cases, this option adds very little from a safety perspective. Still, if you want an autologous blood transfusion for your own peace of mind, all blood centers offer the option.

Autologous blood donation is the process of donating one's own blood prior to an elective surgical or medical procedure to avoid or reduce the need for an allogeneic blood transfusion (from a volunteer blood donor).
The most common form of autologous donation is called preoperative autologous blood donation (PABD). PABD is generally indicated when there is a reasonable chance that a blood transfusion will become necessary, when the patient is in adequate health to donate blood, and when there is sufficient preoperative time for the patient to donate. As the shelf life of liquid blood is approximately 42 days, the patient may begin donating up to six weeks before the scheduled procedure. It is generally recommended that a patient donate no more than once or twice a week, and no later than 72 hours before surgery.

This is a blood transfusion of your own blood which you have previously had stored.
