In order to determine if there is a potential organ match for a transplant, doctors perform these three tests.

a-cross-matching, donor screening, and white blood cell levels

b-blood type, tissue type, and cross-matching

c-organ matching, donor screening, and genetic analysis

d-blood typing, genetic screening, and donor testing

Blood Type, Tissue Type, and Cross Matching is the correct answer, because Doctors cannot transplant just any organ into a patient; the organ must be a specific match. The organ originated must have a compatible blood type. If not, the recipient's body will see the new organ as a foreign body, and the transplant will fail. Finally, doctors look to see if the immune system contains any antibodies that will fight off the new organ. If any of these conditions are not met, the donor organ will go to another match.
