What's this test for?

This test is ideal if you're concerned about colorectal cancer risk, experiencing digestive symptoms like abdominal discomfort, or simply due for routine screening (especially if you're over 50). It detects hidden blood in your stool that isn't visible to the naked eye, which can be an early warning sign of polyps, colorectal cancer, or other digestive conditions. Many people use this test as part of preventive care even without symptoms, as early detection significantly improves treatment outcomes.

How should I prepare for this test?

You'll need to visit the lab to get the InSure FOBT test card before collection. Collect fecal specimens from toilet water and brush them onto the test card, then keep the specimen at room temperature and note the collection date and time. This test is not available for California, Missouri, or Pennsylvania residents.

What's included in this test?

This test measures fecal globin using immunochemistry (InSure FOBT), which specifically detects human hemoglobin in stool samples. This advanced method is highly sensitive to blood from the lower digestive tract where colorectal cancers and polyps typically develop. Unlike older tests, this immunochemical approach minimizes false positives from dietary sources and provides reliable screening for early-stage colorectal disease.

What happens after I get my results?
You'll receive doctor notes in simple language explaining whether occult blood was detected and what that means for your digestive health. The notes provide personalized guidance on next steps, such as dietary considerations, whether you need follow-up testing like a colonoscopy, or if routine rescreening is recommended. Along with your standard lab report, you can track results over time using our trends feature to monitor your digestive health during routine screenings.
Who should consider getting this test?
This test is important for adults over 50 as part of routine colorectal cancer screening, or younger adults with a family history of colorectal cancer or polyps. It's also recommended if you're experiencing unexplained changes in bowel habits, abdominal discomfort, unexplained weight loss, or other digestive symptoms. Anyone at increased risk due to inflammatory bowel disease or other digestive conditions should discuss regular screening with their doctor.
What symptoms indicate I may need this test?
Consider this test if you notice changes in bowel habits like persistent diarrhea or constipation, abdominal pain or cramping, unexplained weight loss, or ongoing fatigue. Other signs include feeling that your bowel doesn't empty completely, narrow stools, or any digestive discomfort that persists. Even without symptoms, routine screening after age 50 is recommended as colorectal cancer often develops without early warning signs.
How can I support my digestive health naturally?
Supporting digestive and colorectal health starts with a high-fiber diet rich in fruits, vegetables, and whole grains, which helps maintain healthy bowel movements. Limit red and processed meats, avoid excessive alcohol, and maintain a healthy weight through regular exercise. Stay hydrated, manage stress through relaxation techniques, and avoid smoking, which increases colorectal cancer risk.
What does a positive result mean?
A positive result means that hidden blood was detected in your stool sample, which requires follow-up investigation. While this doesn't automatically mean cancer, it indicates that further testing like a colonoscopy is needed to identify the source, which could be polyps, hemorrhoids, ulcers, or other digestive conditions. Early detection through positive screening often leads to finding and removing precancerous polyps before they develop into cancer.
How often should I get screened for colorectal cancer?
If your results are normal and you have average risk, annual fecal occult blood testing is typically recommended starting at age 50 (or 45 according to newer guidelines). If you have a family history of colorectal cancer or polyps, your doctor may recommend more frequent screening or starting at an earlier age. After a positive result or if polyps are found, your doctor will create a personalized screening schedule based on your specific situation.
What happens if blood is detected in my stool?
If blood is detected, your doctor will typically recommend a colonoscopy to visually examine your colon and identify the source of bleeding. This allows direct visualization and removal of any polyps found, which can prevent cancer development. The source could be benign conditions like hemorrhoids or more serious issues like polyps or cancer, so follow-up is essential for proper diagnosis and treatment planning.
