Additional Information

Limitations:

No interference from foods or drugs that interfere with guaiac-based tests. Detects blood only from lower gastrointestinal tract.

Toilet freshener should be removed and toilet flushed prior to sample collection.

Clinical Significance:

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.
