Cologuard Tests. Cologuard is a new,stool-based testand also can be known as the fecal immunochemical test (FIT). These stool-based tests can be done at home have a much higher sensitivity and specificity for colon cancer. The Cologuard test determines if there is blood in your stool,if there are precancerous polyps,or abnormal DNA.

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.
What is the difference between colonoscopy and Cologuard?
With colonoscopy, we are able to completely remove polyps or biopsy suspicious lesions. Cologuard is a new, stool-based test and also can be known as the fecal immunochemical test (FIT). 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.
