Fecal Occult Blood, Immunoassay

Item Catalog Number: LC182949

This test is intended for the detection of hemoglobin from blood in fecal specimens. This test is designed for preliminary screening. A positive result should be followed up with additional diagnostic procedures, such as colonoscopy or sigmoidoscopy, to determine the exact cause and source of the blood in the feces.

A negative result can be obtained even when a gastrointestinal disorder is present. For example, some polyps and colorectal cancers may bleed intermittently or not at all during certain stages of disease. False-negative results may occur when occult blood is not uniformly distributed throughout the stool.

Repeat testing is recommended if a pathological condition is suspected. Urine and excessive dilution of specimens with water from the toilet bowl may cause erroneous results. For best results, use the collection paper in the collection kit.

Alcohol and certain medications, such as aspirin, indomethacin, reserpine, phenylbutazone, corticosteroids, and nonsteroidal anti-inflammatory drugs may cause gastrointestinal irritation and subsequent bleeding in some patients.

Fasting is not required for this test. Take all medications as prescribed. Do not take your supplements the morning of the test.
