Cologuard prescription available online

Cologuard testing has potential drawbacks, mostly involving the accuracy of the screening test. According to a 2018 review, stool sample testing is not as accurate as a colonoscopy when detecting precancerous polyps or lesions.

False positives can create unnecessary stress and worry while waiting for follow-up test results. Because Cologuard testing produces high levels of false negatives, it's important to talk to your healthcare provider before taking the test.

A false-negative test result—or missing the presence of colorectal cancer—is also possible. In a 2014 study, the false-negative rate was higher for larger polyps. Since Cologuard tests are relatively new, there are not yet any long-term data on how this screening method will affect your outlook if you have colon cancer.

You should call your doctor if you have any concerns about the preventive screening, or if you develop any other new or concerning symptoms.

Cologuard test kits can range from $581 to $681 without insurance.

Most health insurance plans, including Medicare, cover Cologuard. If you're eligible for colon cancer screening and have health insurance, you may be able to get a Cologuard prescription without any out-of-pocket costs.

Avoid using Cologuard if:

• You have diarrhea.

• You're currently menstruating.

• You have rectal bleeding due to hemorrhoids.

Read the instructions on your test kit carefully. Wait until you're ready to have a bowel movement to use your Cologuard test. Make sure you can ship the sample within 24 hours.
