Facebook Is a Great Place to Find a Kidney

People are increasingly turning to social media to search for kidney donors—and it turns out Facebook is actually a pretty great place to find one. In a study of almost 100 Facebook pages set up for the purpose, researchers found that nearly one-third had potential donors step forward to check if they were compatible, and one in eight actually snagged a donor. One site, appealing for a kidney for a young child, actually encouraged more than 600 potential donors to be tested, the Daily Mail reports.

The pages were set up by the patients in 37% of cases, by their children in 31% of cases, and by other family members or friends in 32% of cases. But some scientists are concerned that such appeals rarely warn about the downsides of organ donation—just 5% of pages mentioned medical risks, and only 11% mentioned costs to the donor.
