The Biorepository will guide the Diabetic Foot Consortium (DFC) activities for collection and storing biosamples and data from participants enrolled in other current and future DFC research studies.

Official Title

Adjunct Collection of Additional Biorepository Data From Patients Enrolled in DFC Trials


Participants enrolling in a parent DFC research study will be concurrently approached about participating in the DFC Biorepository as well. If agreeable, participants will be asked to provide blood, urine, wound debridement tissue and wound dressing samples at the time of enrollment and once more if appropriate and as coincides with the primary study visit schedule. Participants will also be contacted via phone for every six months for two years thereafter to gather longitudinal data about their wound. Data and samples from the Biorepository, along with data collected during the primary study will be available to ancillary researchers.
