Fecal occult blood (FOB)

Fecal occult blood (FOB) test is a test to check for hidden blood in the feces. It is performed as part of the routine stool examination during the examination of the rectum for colorectal cancer. Fecal occult blood may be due to a number of causes. The source of the bleeding may be anywhere in the gastrointestinal tract. The Fecal Occult Blood Rapid Test is a rapid chromatographic immunoassay for the qualitative detection of human occult blood in feces by professional laboratories or physician’s offices. The Test employs a unique combination of monoclonal and polyclonal antibodies to detect only human blood in stool. As a result, abstinence of food and drug before taking this test is no longer necessary.
