Each unit of blood is broken down into components, such as red blood cells, plasma, cryoprecipitated AHF, and platelets. One unit of whole blood, once it's separated, may be transfused to several patients, each with different needs. Annually, more than 21 million blood components are transfused.

Who are the blood donors Most blood donors are volunteers. However, sometimes, a patient may want to donate blood a couple of weeks before undergoing surgery, so that his or her blood is available in case of a blood transfusion. Donating blood for yourself is called an autologous donation.

(T-lymphocytes can cause a reaction when transfused, but can also cause graft-versus-host problems with repeated exposure to foreign cells.) Leukocyte-reduced blood has been filtered to remove the white blood cells that contain antibodies that can cause fevers in the recipient of the transfusion. (These antibodies, with repeated transfusions, may also increase a recipient's risk of reactions to subsequent transfusions.)
