Like most people, celebrities who donated kidneys had to be a perfect match for the recipient or else the organ could be rejected. This used to be a huge problem, but doctors can now do tests to see if a donor will be compatible for giving a kidney.
The most common type of organ transplant is kidney donation because kidneys are relatively easy to donate. (Check out this list of Famous Kidney Transplant Recipients). People are usually born with two kidneys and are able to recover relatively quickly if they donate theirs. Use this list as a reference to see which famous people have donated their organs.
