My test results came back. I am not a complete match for my sister. We now need to check the registry to see if a better match is available. While you can do a transplant with a not-perfectly-matched donor, that sets up a risk of rejection and "graft vs. host disease."
On that note, we now have a URL that will let me track conversions:
http://join.bethematch.org/gosusan Please use this URL if you decide to share pointers to the registry.
I've been appending # markers as a crude method for determining which channel led to the URL, e.g.
http://join.bethematch.org/gosusan#fb1 http://join.bethematch.org/gosusan#adcenter...
Thanks again for everyone's good wishes, consideration of signup, and so on.
