About Cologuard Cologuard was approved by the FDA in August 2014 and results from Exact Sciences’ prospective 90-site, point-in-time, 10,000-patient pivotal trial were published in the New England Journal of Medicine in March 2014. Cologuard is included in the recommendations of the U.S. Preventive Services Task Force (2016) and the American Cancer Society’s (2014) colorectal cancer screening guidelines.  Stool DNA is included in the combined screening guidelines of the American Cancer Society/U.S. Multi-Society Task Force/American College of Radiology (2008), the American College of Gastroenterology guidelines (2009) and the National Comprehensive Cancer Network (2016). Cologuard is indicated to screen adults of either sex, 50 years or older, who are at average risk for colorectal cancer. Cologuard is not for everyone and is not a replacement for diagnostic colonoscopy or surveillance colonoscopy in high-risk individuals. False positives and false negatives do occur. Any positive test result should be followed by a diagnostic colonoscopy. Following a negative result, patients should continue participating in a screening program at an interval and with a method appropriate for the individual patient. Cologuard performance when used for repeat testing has not been evaluated or established. For more information about Cologuard, visit www.CologuardTest.com. Rx Only. About Exact Sciences Corp.
