We are looking for exceptionally healthy people aged 18-50 in the Boston area to donate their stool. This stool is used to treat patients suffering from recurrent episodes of C. difficile infection, via a procedure called a fecal microbiota transplant (FMT); more than 17,000 patients have received FMT materials from OpenBiome since 2012. Stool donations are also used in clinical research across the U.S. exploring the use of FMT to treat a range of diseases including ulcerative colitis, Crohn’s disease, and irritable bowel syndrome (IBS).

Prospective donors go through a series of health screens to determine their eligibility to donate stool. If you:

  • can make daily trips to one of our two locations (196 Boston Avenue, Medford or 200 Inner Belt Drive, Somerville) location for at least 60 days
  • are between 18-50 years old
  • have a Body Mass Index (BMI) < 30
then you could be a stool donor!
As compensation for their commitment, donors receive $40 for every stool they donate for research.
Take our donor survey now to start the process to become a stool donor, or contact zac@openbiome.org if you have any questions. For more information see www.openbiome.org/stool-donation/ .
