SENSITIVITY & SPECIFICITY

The Cologuard® test effectively detects colorectal cancer (CRC) and precancer as the best-in-class noninvasive screening option1

In a 2014, prospective, head-to-head, point-in-time, 90-site, pivotal study of 10,000 patients aged 50 to 84 years at average risk for CRC, published in The New England Journal of Medicine, the Cologuard test demonstrated1*:

Sensitivity
92%

in detecting CRC stages I to IV1

94%

in detecting early CRC stages I to II1-3†

Specificity
87%

overall1‡

90%

in clean colonoscopy1‡

False positives and false negatives did occur in this pivotal study. 13% of patients without CRC or advanced adenomas received a positive result (false positive), and 8% of patients with cancer received a negative result (false negative). The clinical validation study was conducted in patients 50 years of age and older. Cologuard performance in patients ages 45 to 49 years was estimated by subgroup analysis of near-age groups.

The Cologuard test is an effective screening option that may help you rule out CRC1

84%

of Cologuard patients tested negative

In clinical practice, these patients would not need to undergo a screening colonoscopy

99.94%

negative predictive value (NPV)

With a negative result, there was a 99.94% chance that a patient would not have CRC

* In the pivotal study, screening colonoscopy was the reference method.1
Statistic calculated using data from the pivotal study and reported within the Ahlquist review article. Cologuard sensitivity, per stage of cancer: I: 90% (n=29); II: 100% (n=21); III: 90% (n=10); IV: 75% (n=4).2,3
Cologuard specificity: 87% overall specificity, excluding CRC and advanced adenomas, and including all nonadvanced adenomas, nonneoplastic findings, and negative results on colonoscopy. There was 90% specificity in participants with no lesions biopsied on colonoscopy.1

Negative predictive value (NPV) is defined as the probability that disease is absent in those with a negative result; it is highly dependent on the prevalence of the disease. NPV was derived from the patient population evaluated in the lmperiale et al publication.1
