Some years back I read (sorry, I can't remember where) that a good number of "Prior Living Donors" did not receive "priority" when they needed a transplant simply because nobody remembered to list them as being Prior Living Donors, so they stayed on the wait list. It was said at that time that Prior Living Donors, if they find themselves later in need of a transplant, should ASK and make SURE that their status as prior donors has been registered.
