ColonSentry® is a convenient blood test that measures the expression of seven gene biomarkers (signatures) in the blood that are early warning signs of colon cancer.

  • ColonSentry is simple & convenient and can be done at your annual exam
  • ColonSentry requires no fasting, dietary restrictions, or special instructions
  • ColonSentry does not require you to provide or handle a stool sample

The ColonSentry® blood test can be done at the same time as your annual blood-work to help identify your current risk for having colorectal cancer. ColonSentry can be used as a decision tool to help patients and physicians follow up with the recommended screenings for colorectal cancer.

Why Get Tested?

Colorectal cancer (CRC) is the most preventable and treatable form of cancer when detected early,3 yet people often delay or avoid getting tested until symptoms appear. Discomfort and complications with common test options, like colonoscopies and stool-based tests, causes too many patients to ignore recommended CRC screening guidelines. As a result, most cancers are detected in late stages when they are least curable.

Patients who avoid CRC screenings are taking an unnecessary gamble. The  ColonSentry® test can help you and your medical provider make better decisions regarding the need for a colonoscopy. Colorectal cancer, if caught early, can be beaten. The choice to act is yours.

Take Action

STEP 1 – Get Tested

According to the Centers for Disease Control and Prevention (CDC), screening for colorectal cancer using high-sensitivity fecal occult blood testing, sigmoidoscopy, or colonoscopy should begin at age 50 and should continue until age 75.10 The American College of Gastroenterology suggests that African Americans begin screening with colonoscopies at age 45.7 People with a higher risk of developing colorectal cancer should begin screening at a younger age and may need to be tested more frequently. Download the ColonSentry brochure to discuss with your doctor.

STEP 2 – Understand Your Results

Arrange an appointment to discuss your results and risk score with your medical practitioner. Together you and your doctor can determine if you should have further screenings.

STEP 3 – Follow Your Doctor's Plan

Colorectal cancer caught in its early stages can be beaten. It is critical that you follow your medical provider’s advice, which may include the need for a colonoscopy, other diagnostic tests and treatments.

About Colorectal Cancer

Colorectal cancer (CRC) occurs when cells lining the colon or rectum begin to divide rapidly and form small tumors or premalignant polyps. Though usually benign, some of these polyps may become malignant or cancerous over time. If these cancerous cells grow into the wall of the colon or rectum, the cancer can spread to other organs in a process called "metastasis."
