Colonoscopy vs. Stool Tests
Not all colon cancer screening options are created equal. Understanding the differences between screening methods is essential for making informed decisions about your health. While at-home stool tests can detect signs of cancer, they do not prevent it nor remove dangerous polyps. In contrast, a colonoscopy is the only test available that simultaneously detects and removes threats of colorectal cancer during a single procedure. This proactive approach makes colonoscopy the gold standard in colorectal cancer screening, providing unmatched benefits for your long-term health and peace of mind.

Why choose a colonoscopy?
Comprehensive Examination
A colonoscopy enables your surgeon to thoroughly examine the entire length of your colon and rectum. Stool-based tests, however, only analyze samples for potential signs of cancer or polyps, without direct visualization.
Detection and Immediate Treatment
With a colonoscopy, polyps—small growths on the colon lining—can be detected and removed immediately during the procedure. In contrast, a positive stool-based test requires a follow-on colonoscopy for further investigation, delaying treatment and potentially increasing costs. It’s also important to note that roughly 1-in-10 stool-based tests return false-positive results, which may result in a follow-on colonoscopy.
Effective Cancer Prevention
By removing polyps promptly, colonoscopies significantly reduce the risk of colorectal cancer. Stool-based tests cannot prevent cancer directly and require additional procedures if abnormal results are found.
Insurance Coverage and Cost Considerations
Most insurance plans fully cover colonoscopies when performed as preventive screening. However, if a stool-based test returns a positive result, the necessary follow-on colonoscopy is often classified as diagnostic rather than preventive. Diagnostic colonoscopies typically are not fully covered and may involve additional charges like co-pays and deductibles.
If you have any questions about your coverage, we encourage you to reach out directly to your insurance provider for clarity. This can help you avoid surprise costs.
