Average risk patients
Subjects will be men and women, 50-84 years of age, inclusive, each with a screening colonoscopy resulting in normal findings.

Primary Outcome Measures :
  1. Sensitivity and Specificity of the Exact CRC diagnostic screening test. [ Time Frame: 10 months ]
    The primary endpoints are point estimates of the sensitivity of the diagnostic tests for detection of colorectal neoplasms.

Biospecimen Retention:   Samples With DNA
Provide anonymous, clinically characterized specimens for bio-repository for future colorectal cancer-related test development.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Patients are at average risk of developing colorectal cancer at the time of their colonoscopy and the colonoscopy resulted in normal findings.

Inclusion Criteria:

  • Subject is male or female, 50-84 years of age, inclusive.
  • Subject is at average risk for development of CRC and has undergone a screening colonoscopy with a normal result at least 30 days and no more than 120 days before providing a stool sample for the study. For the purposes of this study, a "normal" colonoscopy result is defined as no polyps of any size detected or removed (including benign, hyperplastic polyps).
  • Subject is able to understand the study procedures, and is able to provide signed consent to participate in the study and authorizes release of relevant protected health information through signing a HIPAA consent.
  • Subject is able and willing to provide stool samples at least 30 days and no more than 120 days after undergoing a colonoscopy that resulted in normal findings, according to the written instructions provided to them.

Exclusion Criteria:

  • Subject has any condition which, in the opinion of the investigator should preclude participation in the study.
  • Subject had any findings on recent or any previous colonoscopy including benign, and/or hyperplastic polyps of any size. (Note: Tissue biopsies that result in no histopathology findings are acceptable.)
  • Subject has a history or recent diagnosis of CRC or adenoma.
  • Subject has a history of aerodigestive tract cancer.
  • Subject has had a positive fecal occult blood test or FIT within the previous six (6) months.
  • Subject has had a prior colorectal resection for any reason other than sigmoid diverticular disease.
  • Subject has had overt rectal bleeding, e.g., hematochezia or melena, within the previous 30 days. (Blood on toilet paper, after wiping, does not constitute rectal bleeding)
  • Subject has a diagnosis or personal history of any of the following high-risk conditions for colorectal cancer:

    • Inflammatory bowel disease (IBD) including chronic ulcerative colitis (CUC) and Crohn's disease.
    • Greater than or equal to (>=)2 first-degree relatives who have been diagnosed with colon cancer. (Note: first-degree relatives include parents, siblings and offspring).
    • One first-degree relative with CRC diagnosed before the age of 60.
    • Familial adenomatous polyposis (also referred to as "FAP", including attenuated FAP).
    • Hereditary non-polyposis colorectal cancer syndrome (also referred to as "HNPCC" of "Lynch Syndrome").
    • Other hereditary cancer syndromes including but are not limited to Peutz-Jeghers Syndrome, MYH-Associated Polyposis (MAP), Gardner's Syndrome, Turcot's (or Crail's) Syndrome, Cowden's Syndrome, Juvenile Polyposis, Cronkhite-Canada Syndrome, Neurofibromatosis and Familial Hyperplastic Polyposis.
