Nancy,
Even when I was donating to my Uncle the facility would not share any information with either of us about the other. And, we each had separate transplant coordinators assigned. Oddly enough they were not allowed to share some details among themselves. It proved to be a pain in the butt; however, I understand from the facilities perspective why they have this practice. I was allowed to divulge information directly that I wanted to share. And, I was always told I could back out at any point and my Uncle would only be told that an issue arose making me a non-suitable donor.
Though it sounds odd, one of the primary goals is to ensure that donors are not pressured into donating and that they have the freedome to change their mind without worry of judgement. Of course there are hosts of other reasons that they do it as well.
Good luck on your journey!
