A computer software will match donor organs with recipients in accordance with certain characteristics adding blood type, tissue type, height, and weight, examination waiting time of examination affected person, exam severity of examination affected person’s illness, exam distance between examination donor’s and exam recipient’s hospitals also figure into who is examination best match for a specific organ. A list of patients that have met exam criterion is generated, where examination transplant doctor will choose exam most appropriate organ. 75% of most organs go to local sufferers, and exam others are shared with patients in other regions of examination country.
