GENERAL ENROLLMENT REQUIREMENTS
FOR SOLVE CFS BIOBANK
Current as of June 8, 2010
The Solve ME/CFS Initiative is now inviting participation in the SolveCFS BioBank under a new category, “General Enrollment.” This enables interested individuals to provide written informed consent and complete detailed clinical questionnaires to become part of future SolveCFS BioBank studies. Blood and tissue samples will be requested from enrollees as they become eligible for approved studies. Creating this new enrollment status facilitates greater participation by members of the community, expands the clinical population available to interested investigators, and enables the Association to defer the expense of sample collection until those samples are needed for an approved study.
A subject will be eligible for general enrollment in the SolveCFS BioBank if they have previously been diagnosed with CFS by a licensed physician using either the Fukuda (1994) research criteria or the Canadian (2003) clinical criteria. The general inclusion and exclusion criteria listed below also apply. Stricter requirements apply to BioBank enrollees included the current BioBank study. Requirements for participation in the BioBank may change as further collaborations develop. Please check www.SolveCFS.org frequently for updates about the SolveCFS BioBank.
