How closely related does someone need to be to donate a kidney?

The good news is that kidney donors don't have to be blood relatives at all. While family members like siblings, parents, or children are often tested first because they may have a better chance of being a match, many successful transplants happen between people who aren't related.

Your brother would be a good starting point since siblings have about a 25% chance of being a match. However, nieces, nephews, and even more distant relatives like great-nieces and great-nephews can also be potential donors.

Beyond family, friends, spouses, coworkers, or even altruistic strangers can donate if they're compatible. What matters most is tissue compatibility and blood type matching, not how closely you're related.

If you're considering a transplant, talk to your transplant team about testing potential donors. They can help coordinate the evaluation process for anyone willing to be tested, regardless of their relationship to you.
