A fecal occult blood test is a qualitative detection chromatographic immunoassay for human occult blood in feces. Anti-hemoglobin antibodies are pre-coated on the membrane on the test line of the test. The specimen reacts with the anti-hemoglobin antibody. The created mixture moves upward by capillary action on the membrane chromatographically. The mixture reacts with the anti-hemoglobin antibody on the membrane which creates a colored line. If a colored line is formed, it shows a positive result and if no line is formed that means the results are negative. All tests have a control line to indicate that there has been enough volume of the specimen used.
Most diseases do not show any visible symptoms but can only be detected in occult blood. Those diseases include, for example, colon cancer, ulcers, polyps, colitis, diverticulitis, and fissures. Fecal occult blood test detects low levels of fecal occult blood in feces. Fecal occult blood test uses a double-antibody sandwich assay to detect 50ng/mL of hemoglobin or 6 µg hemoglobin/g feces.
The specimen should not be collected during the menstrual period or 3 days after, or if there is bleeding hemorrhoid or blood in the urine. Alcohol, aspirin or other medication should not be used at least 48 hours before testing, because it may cause gastrointestinal irritation that leads to occult bleeding.
Fecal occult blood occurs usually from a slow bleeding from the inside of the lower or gastrointestinal tract. Slow bleeding does not make the feces to change the color to a bloody red color. In this case a test is required in order to find the bleeding. Fecal occult blood test is used to detect colon cancer in people without intestinal symptoms. Colon cancer causes also other symptoms such as abdominal pain, rectal bleeding or changes in bowel habits.
