For example, a colonoscopy is the most accurate at finding polyps, but it is also the most invasive. For this reason, a colonoscopy does not need to be repeated as frequently as other types of screening if no abnormalities are initially found. The goal of colorectal cancer screening is to find abnormal growths before they can become cancer or to find cancer at an earlier point when it is easier to treat.
Insurance may cover some FIT kits, but it’s not a guarantee. If you have insurance, it’s a good idea to call your provider to find out about cost. If your insurance doesn’t cover the cost of FIT, some affordable options are available. A FIT test is a fecal immunochemical test, while Cologuard is a particular test. Cologuard is different compared with other FIT options, because it looks for certain DNA markers and can test for both precancer and cancer. A 2019 review shows FITs are almost as effective as colonoscopies, but colonoscopies are considered the gold standard in screening.
FITs must be done more frequently than colonoscopies

The test may detect abnormalities in other abdominal organs and additional tests may be needed to determine the cause.
You can store the sample on the Hemoccult slide for up to 7 days. Be sure to keep the sample in a safe place away from heat, light, and children. Your healthcare provider will give you directions of where to take or mail your stool samples. Customers who purchase Everlywell’s test kits collect their samples at home and return the samples to a partner laboratory that is CLIA certified.
When should I get an at-home colon cancer test?
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.
Testing yourself for colon cancer is now easier and more accurate. Cologuard is a do-it-yourself kit that allows you to collect your stool sample in the privacy of your home. This is similar to flexible sigmoidoscopy, except the doctor uses a longer, thin, flexible, lighted tube to check for polyps or cancer inside the rectum and the entire colon. During the test, the doctor can find and remove most polyps and some cancers.
Best for Rapid Results
The lab will return the results to your physician or healthcare provider who will contact you as soon as they arrive. This means that you simply need to brush the stool sample in your toilet with the long brush provided and brush the toilet water on the test card. There are no dietary or medication restrictions that you need to follow before taking the test. The test is provided by a prescription from your physician and you can submit the test to your physician or laboratory for analysis. This colorectal screening test is a combination of two tests, the fecal immunochemical test and a DNA screening for abnormal cancer cells. Lab pathologists test stool samples for increased levels of mutated or altered DNA biomarkers that are found in shedded colon cells.
Less accurate than either the FIT or the DNA stool test, it identifies cancer only 20 to 50 percent of the time. Depending on where you live, a sigmoidoscopy might be more available than a colonoscopy, and it can be done without sedation, though it’s not as thorough. Like standard colonoscopy, a thorough cleansing of the bowel is required beforehand. Unlike traditional colonoscopy, virtual colonoscopy doesn't require sedation or the insertion of a scope into the colon. Abnormal tissue, such as polyps, and tissue samples can be removed through the scope during the exam.
Chemotherapy during pregnancy?
Since the test checks for blood, it’s important to wait to take it if you have blood in your stool from hemorrhoids or blood in your urine. You should also wait to take the test if you just started your menstrual cycle. Once the CAP-accredited, CLIA-certified lab receives your sample, it will conduct the FIT to check for blood in the stool. Results are usually available within two days after your sample arrives. A fecal occult blood test measures whether there are microscopic traces of hemoglobin in the stool. Approximately 10% of participants used the self-order function on the kp.org website to order an at-home test kit for colorectal cancer.
To help create clear images, a small tube is placed inside your rectum to fill your colon with air or carbon dioxide. For this test, you collect a stool sample at home and send it to a laboratory for testing. If you're reluctant to make a decision, remember that any discomfort or embarrassment from colon cancer screening is temporary — and detecting problems early could save your life.
The FIT-DNA test combines the FIT with a test that detects altered DNA in the stool. For this test, you collect an entire bowel movement and send it to a lab, where it is checked for altered DNA and for the presence of blood. A colonoscopy is one of several screening tests for colorectal cancer. Ask your doctor and have a frank discussion about your risks and concerns. Most people find colonoscopy less miserable than they anticipate, and it is still the best option overall. Higher-risk people really do need a colonoscopy, usually until age 80.
Talk to your healthcare provider if you want further testing or have any questions about the results. There has been little research on tests that are available to purchase over-the-counter without guidance from a healthcare provider. However, an FIT can also be ordered by a physician and the sample can be collected either in the doctor’s office, at a laboratory, or at home. One meta-analysis looked at FIT done as ordered by a doctor. In people who were at average risk of colon cancer, the FIT found 91% of cancers. At-home colorectal cancer tests detect blood that may be due to the presence of polyps in the colon or rectum.
This may — to varying degrees — include avoiding solid food the day before the exam, adjusting your medications, and drinking a laxative solution or using enemas to empty your colon. Place samples inside the zippered bag inside the tray that is inside the shipping box. Collect a sample of your stool using one end of the applicator stick.
Another type of home test—and one that is newer to the market—is a stool DNA test, also known as FIT-DNA. Sold under the brand name Cologuard®in the U.S., this test looks for blood and certain DNA mutations in genes that may signify cancerous or precancerous cells. People at high risk of colon cancer should still undergo a colonoscopy. Experts in a 2018 review considered FIT to be the better testing option for a couple of reasons. Not only is the FIT more effective at detecting blood in the stool, but it also doesn’t require any prep before testing.
