Stool - Occult Blood (Fecal Occult blood test - FOBT)

Stool - Occult Blood (Fecal Occult Blood Test - FOBT)

The Stool Occult Blood Test (FOBT) is a specialized laboratory screening test used to detect hidden (occult) blood in stool that may not be visible to the naked eye. This test is an important tool for identifying gastrointestinal bleeding, colorectal abnormalities, ulcers, polyps, inflammatory bowel disease, and early signs of colorectal cancer.

Occult blood may appear in stool due to bleeding anywhere along the digestive tract, including the stomach, intestines, colon, or rectum. Since hidden blood often occurs without noticeable symptoms, this test helps detect underlying digestive conditions early, allowing timely medical intervention.

FOBT is widely used as a preventive screening test, especially for individuals at risk of colorectal disease.
