In the SPPIN study, participants are asked to collect stool samples both for themselves and their children. The process is straightforward and can be done in the comfort of your own home. For each session, participants will receive a kit by mail containing clear instructions and all necessary materials. Once the samples are collected, participants securely package them and return them to our lab using a prepaid envelope. It is is a simple and convenient process. For a detailed guide on sample collection, please watch the instructional video below.
