  • The presence of fecal occult blood in the stool is associated with gastrointestinal disorders such as polyps, diverticulitis, and Crohn's disease, which may lead to colorectal cancer if not detected and treated early. Compared to the widely available Guaiac test, the One Step Fecal Occult Blood (FOB) Test by Blue Cross is an immunochemical assay with much higher sensitivity and is designed to be more specific in detecting low levels of human fecal occult blood. It does not require special dietary restriction on patients. One Step Fecal Occult Blood Test is a rapid test that can be performed without the use of an instrument. Test yields a positive result when the concentration of hHb in test specimen is at or above 100ng/ml.
