Detecting Colorectal Cancer Early Saves Lives. Get the Blood Test that Finds it Early.

About The ColonSentry Test

ColonSentry, is the first liquid biopsy for CRC, using our patented Sentinel Principle Technology Platform and has been used on more than 100,000 patients nationwide. If your ColonSentry score is elevated, there is an increased probability you may have Colorectal Cancer. (1-3)

  • No Dietary Restrictions​
  • No Need to Handle Messy Stool

Why Get Tested?

When Colorectal Cancer is found early, the five-year survival rate is 91%. When Colorectal Cancer is found late, the five-year survival rate is 14%.(4) ColonSentry needs to be prescribed by a physician and is available through AVRT,  our comprehensive telehealth program that uses advanced diagnostics and physician supervision to help patients detect cancer in the earliest stages. Whether you have a family history of cancer or are simply concerned about developing cancer, our physicians can work with you to develop a patient-centric, personalized care plan to help optimize your health.
