Clinical Significance

A positive fecal occult blood test (FOBT) indicates invisible blood in the stool, signaling gastrointestinal (GI) bleeding from conditions like colorectal cancer, polyps, ulcers, or hemorrhoids. It is a critical, noninvasive screening tool used to detect early-stage cancers, requiring follow-up diagnostic procedures such as a colonoscopy to confirm the source.
