For prospective donors: If you are able to make daily trips to our lab in Cambridge, MA and are interested in becoming a stool donor, please review the information here to sign up for our stool donor registry.

For patients: We are only able to provide stool material to physicians, for use in clinical settings. Generally, FMT is only available for the treatment of recurrent C. difficile infection. In all other cases, FMT must be conducted as part of a clinical trial. You may review trials that are seeking patient enrollment at More detail is available in our Patient FAQs section.
