Rachel finds out that her crossmatching test is good and has her second appointment with Dr. Matas, the Kidney Transplant Surgeon at the University of MN. He explains that due to the previous surgery she had on her right kidney (she was born with a narrow ureter that had to be surgically repaired) there was likely to be too much scar tissue to perform a successful transplant.  Another concern is that one of her kidneys may not function as well as the other and they would not want to leave her with that kindey nor give it to Matt.   He encourages her to continue advocating and raising awareness for her brother.
