Scientific definitions for transfusion


[ trăns-fyōōzhən ]

  1. The transfer of blood or a component of blood, such as red blood cells, plasma, or platelets, from one person to another to replace losses caused by injury, surgery, or disease.

The blood of the donor is shown to be histologically compatible, or crossmatched, with that of the recipient before transfusion. See more at Rh factor. See Note at blood type.
