The collection process depends on the agency involved. One agency here in Canada gives donors a special attachment that is placed over a toilet seat. The attachment contains a plastic container for stool collection. Once the stool has been deposited, the container must be packaged according to instructions and taken to the agency.
Based on the agency’s requirements, before becoming a donor, a person must complete a questionnaire and undergo blood and stool tests. The blood and stool are checked for pathogens. Some examples of pathogens tested for by different agencies are Clostridium difficile, Giardia, Cryptosporidium, Isospora, Helicobacter pylori, and Rotavirus.
