    By definition, occult gastrointestinal (GI) bleeding is hidden
    and not apparent on stool inspection. It occurs commonly, but
    a test is required for its detection. Elevated fecal blood levels
    are found in about 1 in 20 adults on prevalence screens [1–4]
    and probably occur episodically in all persons. Although often
    trivial, occult GI bleeding may herald a health-threatening
    lesion arising at any level from mouth to rectum. As such, the
    clinician is challenged when faced with occult GI bleeding.
