If you know someone who is in need of a kidney transplant, I highly recommend contacting this organization, which helped me to get a lot of the information I needed. Laurie Reece is the Executive Director at the Alliance for Paired Donation Program. They work specifically with the concept of pairing you up with other people to exchange "swap" kidneys, if you don't have a direct match.

Go to Google and check out the "Alliance for Paired Donation" program.
This is a great option if you or your friend/family member do not have a direct match for a kidney.
An average of 18 people die each day while waiting for organs. Become a donor today if you can!
