The Stool Occult Blood Test, often called a Fecal Occult Blood Test (FOBT), is a non-invasive screening that detects hidden (occult) blood in stool samples, which may signal bleeding within the digestive tract. Occult blood is not visible to the naked eye but can be an early indicator of colorectal cancer, polyps, ulcers, hemorrhoids, or inflammatory bowel disease. This test is recommended for adults as a routine screening tool, particularly over age 45, or for those with unexplained anemia, abdominal pain, or digestive symptoms. The test uses chemical reagents or immunochemical methods to identify traces of blood. A positive result prompts further diagnostic procedures, such as colonoscopy, to locate the source of bleeding. Dietary restrictions may be advised before the test to avoid false positives. Regular screening with stool occult blood testing plays a significant role in early detection of gastrointestinal conditions, helping prevent severe illness and supporting proactive digestive health management.
