@helpkathy Welcome to Mayo Clinic Connect. It must be frustrating and heartbreaking for your sister to get this kind of news. Being on dialysis is a treatment for kidney disease, but not a cure.

There are several factors that can play into being eligible to receive a kidney transplant. Age is not normally one of them.
-Does your sister have other underlying health issues? Active cancer of any type, or cancer-free for less than 5 years? In my case, I cannot be transplanted due to being an active blood cancer patient. That will never go away, so there is no chance for me to get a transplant.
-Has your sister looked at the criteria for the Yale transplant center? I went to their website but could not track down any information. Sometimes it is as simple as carrying too much weight right now, and needing to lose some pounds.
-Has she reached out to the transplant team itself to question their statement of her not being eligible?
-Not knowing is wearing on both of you. If she cannot get satisfactory answers, she can go to principles of the transplant center, and ask for reasons.
-She can check with her insurance to find out about getting a second opinion.

I would really be interested to know what she finds out. Will you come back and tell me, please?
