Definition of Blood Autodonation
Blood Autodonation is a practice in which a person donates his or her own blood for potential self-use during a major operation or health emergency such as major trauma.
The hospital or blood bank stores the blood for specific and sole use by the person. The person may authorize the hospital or blood bank to release the blood for general use as components (such as albumin and plasma) if he or she does not require it, though guidelines vary according to the procedures in place for collecting autodonated blood. Testing procedures for autodonated may be less stringent than for general blood donation because only the donor will receive the blood.
Most people who choose autodonation do so out of concern about the potential for infection such as hepatitis acquired from general donation blood. Though screening procedures and tests make the blood supply as safe as possible, the risk of such infection remains a possibility.
Autodonation also eliminates the risk for transfusion reaction, which may occur when donor blood carries antibodies that activate an immune response in the recipient. Pretransfusion testing can detect most but not all of these scenarios. Autodonation also ensures the availability of blood for people who have uncommon blood types.
