Everlywell FIT Colon Cancer Screening Test is for you if you are you 45 or older? The at-home Fecal Immunochemical Test (FIT) is designed to be simple and non-invasive to help you stay on top of your health and wellness. Screen for the presence of blood in your stool to help detect early signs of colon cancer. Your test results will show you if you are negative or positive for blood in your stool. A positive result does not mean that you have colon cancer—it simply means you need to share the results with your healthcare provider to discuss next steps, which may include a colonoscopy.
