  • What is the difference between fit/FOBT and Cologuard tests?

  • The fecal occult blood test (FOBT) and fecal immunochemical test (FIT) are both recommended by the U.S. Preventive Services Task Force for at-home colon cancer screenings. Although these tests are recommended annually, the cost of 3 annual FIT/FOBT tests remains less expensive than a single Cologuard test every 3 years.

  • How accurate is the ColoGuard test?

  • How Accurate is the Cologuard test? Cologuard can detect 92% of cancers but only 42% of large precancerous polyps. Cologuard is better at detecting cancer than FIT (92% vs 70% for FIT), but the false positive rate is higher. Cologuard has a 12% false positive rate, and that rate increases as people age.

These stool-based tests can be done at home have a much higher sensitivity and specificity for colon cancer.

  • What is the Cologuard home colon cancer screening test?

  • The Cologuard home colon cancer screening test detects cancer by identifying DNA markers from abnormal cells and occult blood in stool samples. A cancerous tumor in the colon will contain mutated DNA fragments that can be detected with special lab tests like the FIT- DNA test or Cologuard.
