Recruitment into the program requires very little from the patient. A brochure will be mailed to prospective participants prior to a scheduled clinic visit. Following registration for the visit, patients will be approached and recruited; the exact logistics will be determined by the preferences, flow, and physical constraints of the particular clinic. Once consented into the program, extra tubes of blood may be drawn when patients undergo clinically ordered blood draws and any leftover blood or tissues may be used for research along with information from their medical record. Except for the extra tubes of blood, no aspects of a patient’s care will change.
