What does a positive result mean? A negative result?

A positive result does not necessarily mean that you have cancer. It means that Cologuard detected DNA and/or hemoglobin biomarkers in the stool which are associated with colon cancer or precancer. False positives and false negatives occur with Cologuard and appropriate follow-up is important. Patients with a positive result should have a diagnostic colonoscopy. Patients with a negative diagnostic colonoscopy following a positive Cologuard result do not require additional clinical evaluation.

A negative result means that Cologuard did not detect significant levels of DNA and/or hemoglobin biomarkers in the stool which are associated with colon cancer or precancer. False positives and false negatives occur with Cologuard and appropriate follow-up is important. If you have a negative result, you should continue in a screening program appropriate for you, recommended by your doctor. Cologuard is recommended by the American Cancer Society every 3 years.
