- Personal or family history of Familial adenomatous polyposis (FAP).
- Personal or family history of Hereditary non-polyposis colorectal cancer syndrome (HNPCC or Lynch Syndrome).
- Positive fecal occult blood testing (FOBT) within the previous 6 months.
- Positive fecal immunochemical testing (FIT) in the previous 6 months.
- Colorectal resection for any reason other than sigmoid diverticular disease.
- Overt rectal bleeding within the previous 30 days.
- Personal history of any cancer diagnosed <5 years prior.
- Inflammatory bowel disease (IBD), including chronic ulcerative colitis (CUC) and Crohn's disease.

- ≥ 2 first-degree relatives who have been diagnosed with colorectal cancer (Note: First degree relatives include parents, siblings and offspring).
- 1 first-degree relative with CRC diagnosed before the age of 60.
- Have participated or be currently participating in a clinical research study in which an experimental medication has been administered during the 30 days up to and including the date of providing informed consent or may be administered through the time of the colonoscopy.
- Have a medical condition which, in the opinion of the investigator, should preclude enrollment into the study.
