fecal immunochemical test (FIT)

The fecal immunochemical test (FIT) is a simple screening tool used to detect hidden blood in your stool, which can be an early sign of conditions like colorectal cancer or polyps. It uses a special antibody to identify even small amounts of blood, providing a safe, non-invasive way to assess your colon health. Usually done at home with a small sample of stool, the FIT helps doctors determine if further tests, like a colonoscopy, are needed. Regular screening with FIT can catch potential issues early, improving treatment outcomes.
