You can sell your poop for $13,000 a year

As the use of personalized medicine continues to widen, a Massachusetts-based nonprofit organization is looking to get really personal and it's paying good money for healthy stool samples.

The company, OpenBiome, is willing to pay as much as $250 for a week's worth of donations of healthy stool samples, or $13,000 a year, according to The Washington Post.

However, donors must undergo vigorous questioning and stool testing to make the cut.

Over the last four years, only 4 percent of interested donors have passed the screening process, co-founder Mark Smith told WaPo.

The sample is used to treat patients who are sick with infections of a bacteria called C. difficile. It is administered, in frozen form via endoscopy or swallowed capsules.

OpenBiome has already shipped about 2,000 treatments to nearly 200 hospitals in the U.S., according to The Post.

"You're usually helping three or four patients out with each sample, and we keep track of that and let you know," Smith said.
