|Condition or disease||Intervention/treatment|
|Colorectal Cancer||Other: All eligible subjects will provide blood for SEPT9 biomarker testing|
The study is designed as a prospective, open enrollment clinical investigation involving multiple clinical study sites in the United States and Germany. Subjects will be competitively enrolled at multiple sites until at least 50 invasive colorectal adenocarcinoma cases identified by screening colonoscopy and verified by clinical and histopathological examination have been enrolled. The primary objective of the investigation is to evaluate and describe the clinical performance of the Septin 9 Biomarker for detecting the 50 individuals with invasive colorectal adenocarcinoma identified in this population representative of the US screening guideline eligible population. Secondary objectives will be to evaluate and describe performance characteristics of the biomarker in individuals with adenomatous polyps 10 mm or larger, flat lesion (s) or non-invasive adenocarcinoma.
Collaborating sites will identify and contact patients scheduled for screening colonoscopy. These patients may be screened by the PI or designee to determine the patients' appropriateness for, and interest in, study participation. Study site personnel will meet with patients meeting eligibility guidelines and offer them participation. Patients interested in participation and who provide written informed consent will be enrolled as Subjects in the study.

Adults > 50 Years Scheduled for Colonscopy
Average to increased risk adults older than 50 years without symptoms indicative of CRC and designated for colonoscopy.
Other: All eligible subjects will provide blood for SEPT9 biomarker testing
A single blood sample per participant selected according to analysis plan is tested for evidence of methylation of a specific DNA sequence, SEPT9.
- Clinical/surgical diagnosis of invasive colorectal adenocarcinoma detected by optical colonoscopy and confirmed by histology compared to the Septin 9 Biomarker classification. [ Time Frame: One Year ]
- Detection of adenomatous polyp(s) equal to or greater than 10 mm, flat lesion (s) or non-invasive adenocarcinoma by colonoscopy and confirmed by histology compared to the Septin 9 Biomarker classification will also be described. [ Time Frame: One Year ]
Biospecimen Retention: Samples With DNA
