Sorry if this has been addressed but these boards are not particularly easy to navigate.  I have been in search of a national registry of living related kidney donors for a LONG time (I donated in 1984 - so it's been a few years.)  If there is any information available I would be most grateful. 

I believe there living donor registries for Australia, New Zealand, The Netherlands, Norway, and Switzerland.

Here's more on living donor registries from Cristy Wright's Livingdonor101 web site: http://www.livingdonor101.com/livingdonorregistry.shtml

There is no registry in the US.
