In the context of the SRTR metrics, a donor is typically defined as an authorized donor from whom at least one organ (heart, intestine, kidney, liver, lung, or pancreas) was procured for the purpose of transplant. Not all authorized donors become actual donors due to complications that arise during the process or medical findings made during the donation procedure that preclude donation, such as active cancer.
