Who Should Test?
ColoSure™ is a non-invasive, stool DNA colorectal cancer screening test for:- Patients age 50 years and older at average risk for colorectal cancer (CRC)
- Patients not compliant with colonoscopy or who want interim screening between colonoscopies
- Patients who do not have signs and symptoms of CRC
- High-risk patients who are noncompliant with standard screening recommendations or as interim screening between colonoscopies

Note: Stool-based DNA screening tests, such as ColoSure™, are relatively new technologies. They have been incorporated in the American Cancer Society’s guidelines as a CRC screening option; however, the interval to repeat the test has not yet been determined.
