Donor Screening Questionnaire


You are being asked to consider donation of feces (stool) for fecal microbiota transplantation (FMT) to treat patients with various health conditions and further medical research on intestinal microorganisms.

To be a donor, it is necessary that you meet certain criteria.  These criteria are present to ensure you can provide a healthy and safe donation for FMT.  During your “screening” visits, you will be asked a number of questions by the doctor (and possibly a study coordinator, if the FMT is being done as part of a study) to see if you are able to donate.

We realize that some of the screening questions we need to ask are sensitive in nature or could be embarrassing to you.  Therefore, we are giving you this self-screening questionnaire that you may complete in privacy and give to us.  Please read it carefully and simply check either YES or NO at the top of the page.  In the second section (labeled question 6), there is no need for you to indicate to which option you are answering yes – just check at the top of the page if you answer YES to ANY of the options. 

If you have any questions about this questionnaire, please contact the MTOP coordinator  at or 416-340-4800 ext. 8353.

Thank you.
