Limitations: This test detects blood in your stool. There are many conditions that may cause blood in your stool so you must follow-up with your doctor if you receive a "positive" result. This test does not replace a physical exam by your doctor. A "negative" test result means blood was not found in the sample; however, colorectal lesions may bleed intermittently and blood may not be uniformly distributed in or on the stool, so a negative test result may occur even when a gastrointestinal disease is present. Failure to follow the test instructions could affect the test results.

Description: The fecal occult blood test is an immunochromatographic fecal occult blood test that qualitatively detects human hemoglobin from blood in fecal samples. This is a useful screening aid for detecting primarily lower gastrointestinal (G.I.) disorders that may be related to iron deficiency anemia, diverticulitis, ulcerative colitis, polyps, adenomas, colorectal cancers or other G.I. lesions that can bleed. It is recommended for use by health professionals as part of routine physical examinations and in screening for colorectal cancer or other sources of lower G.I. bleeding.
