According to the instructions, only one stool sample is required. Ship the sample to your chosen lab, as specified in the instructions. FIT-DNA Test —This test looks for both blood and changes in the DNA of cells seen with colon cancer and polyps that are turning into colon cancer. The recommended frequency of testing with Cologuard is every 3 years. Most colonoscopies take between 30 minutes and an hour to complete.
Physicians typically order the test to be repeated annually. Sometimes you need more than a test result to understand exactly what’s going on. Labcorp OnDemand provides users with access to PWNHealth physicians to better understand their test results. In the event of a positive test result, a nurse from LetsGetChecked will call in order to discuss the next steps. Results can be checked via the website on a computer or a smartphone. In fact, in many cases, screening can prevent the disease from developing.
How Accurate Is a Stool Test for Colon Cancer Screening?
If there is no blood test detected in your stool sample your fecal occult blood test is negative. Your doctor may recommend that you repeat the test every year if you are at risk for colon cancer. If there is no blood test detected in your stool sample your fecal immunochemical test is considered negative.
In a medical setting, tests like a colonoscopy, virtual colonoscopy, or sigmoidoscopy can be used to generate and analyze images of the inside of the colon and rectum. A sample of tissue from a polyp can also be taken during a colonoscopy or sigmoidoscopy. A positive result on an FOBT or FIT test means that traces of blood were detected in your stool.
Cost considerations
When taken alongside other screening methods, at-home testing becomes fool-proof. A fecal immunochemical test is what’s known as an immunohistochemistry test. This kind of test contains certain antibodies that pick up the presence of blood in your poop. If the test results are normal, your doctor will have you repeat the test each year.

When should I first be screened, at 45 or 50?
But because they are not as effective at detecting polyps, they need to be repeated more frequently than a colonoscopy. For most people, stool-based tests are done about every year, while a colonoscopy is recommended once every ten years. It is important to talk with a health care provider about any specific at-home test result and what kind of follow-up testing is most appropriate. Because at-home stool tests do not detect as many polyps, they are only effective for colorectal screening when they are repeated at regular intervals. Many experts recommend that these tests be performed about every year. If your at-home test is negative, it means that there were no signs of polyps in your colon or rectum that are at risk of developing into cancer at this time.
A positive result on a FIT-DNA test means that blood and/or abnormal DNA were found. After placing a collection paper in the toilet, go to the bathroom normally and allow your stool to fall onto the paper. Then use a collection wand to scrape the stool and collect a very small sample. Place the collection wand in the provided tube, which contains a small amount of a chemical reagent. Shake the tube several times, and then place three drops from the tube onto the test cassette. At-home colorectal cancer testing offers certain benefits and drawbacks that are important to consider when deciding if this type of screening is right for you.
There's no debate that colonoscopy is still the most effective screening exam for colon cancer. The first-rate exam not only detects colon cancers with about 98% accuracy, but it also allows doctors to remove precancerous and cancerous polyps during the procedure. Everlywell offers this test as a form of colorectal cancer screening, and it is only available to people who are over age 45.

The test isn’t as accurate as a FIT or multitarget DNA test and has a higher rate of false results. Rare complications may include bleeding from the site where a biopsy was taken or a polyp or other abnormal tissue was removed, or bleeding from a tear in the colon or rectum wall. The following guidelines are not meant to be taken as instructions but are for informative use only. Only follow the directions provided within the kit and as directed by your healthcare provider.
