Subjects in categories P3 and P4 are scheduled for colonoscopy for one of the following reasons: suspicion of having an inflammatory bowel condition, rectal bleeding, presence of occult blood in stool, unexplained iron deficiency anemia, recent change in bowel habits, family history of CRC or adenomatous polyps or other hereditary colorectal diseases. Often, colonoscopy is not performed within the government-prescribed recommended delays, leading to waiting lists for the procedure. Analysis of NK cell activity may help identify those at risk for the presence of CRC and therefore help prioritize subjects on these waiting lists, help manage resources and help convince subjects to have a colonoscopy. Furthermore, all subjects will undergo a FIT, allowing a determination of the ability of each test alone, as well as a combination of NK Vue and FIT, to predict outcome on colonoscopy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '40 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
