Reflecting a true colorectal cancer screening population in the PRESEPT Study is of utmost importance to the success of the study. To achieve this, all clinical sites have stringent criteria to apply in the enrollment of subjects into the study. For this reason, please understand that participation in the PRESEPT Study is by invitation through a gastroenterologist participating in the PRESEPT Study only, and you cannot volunteer to participate in the study.

Thank you for your understanding.
