ColoHealth is a screening test, designed to detect colorectal cancer early to improve long term prognosis.
ColoHealth is an in vitro test that detects methylated Septin 9 DNA in human plasma, and is less invasive than other methods such as colonoscopy, sigmoidoscopy, and high sensitivity fecal occult blood testing.
ColoHealth is not intended to replace traditional CRC screening methods. When indicated by risk level, patients should be tested for CRC using traditional methods.
Specificity & Sensitivity for ColoHealth
* Note: Follow up with Grail or colonoscopy would be appropriate for higher risk set (PPV 30-40%, NPV: 70-60%).
The total number of cases analyzed for the statistics above was 1,544 individuals (men and women, ages 50-85 who were not considered at a higher risk of developing CRC. Excluded patients included those with rectal bleeding, fresh blood in their stool, or those with an iron deficiency)
