Service DescriptionFecal Occult Blood Testing (FOBT) at Primea Polyclinic in Belgrade is a non-invasive diagnostic assay detecting microscopic blood in stool specimens. The test identifies hidden lower or upper gastrointestinal bleeding to assist in early detection of mucosal lesions or colorectal pathology. Recommended for routine colorectal cancer screening in adults over 50, or for investigating unexplained anemia or bowel habit changes. Dietary restrictions are generally not required; collecting stool samples from three distinct areas of a single bowel movement into a sterile container is recommended.
