C040-C (FOB) Fecal Occult Blood Rapid Test

Gastrointestinal lesions, such as diverticulitis, colitis, polyps, and colorectal cancer, are common causes of gastrointestinal bleeding and fecal occult blood.

Two primary methods are available for fecal occult blood testing: the traditional guaiac FOB test and immunological FOB test. The chemical guaiac tests are less accurate and require diet to avoid foods containing blood for several days before testing to prevent false positives. In contrast, the immunological tests are more accurate and do not require special dietary restrictions prior to the test sample collection.
