Test Overview
Test Methodology

Hemoccult Sensa- oxidation

Test Usage

Performed at authorized locations by point of care operators. Used to monitor gastrointestinal bleeding in patients with iron deficiency anemia or recuperating from surgery, peptic ulcer, ulcerative colitis and other conditions. It is not a test for colorectal cancer or other specific diseases.

Reference Range *

Negative

Test Limitations

•Bowel lesions, including some polyps and colorectal cancers, may not bleed at all or may bleed intermittently. Also, blood, if present may not be distributed uniformly in the fecal specimen. Consequently, a test result may be negative when disease is present.
•Substances that can cause false-positives results: Red meat, Aspirin (> 325 mg/day), non-steroidal anti-inflammatory drugs (e.g., ibuprofen, indomethacin, and naproxen), Corticosteroids, phenylbutazone, reserpine, anticoagulants, antimetabolites, and caner chemotherapy drugs, excess alcohol consumption, and application of antiseptic preparations containing iodine.
•Substances that can cause false-negative results: Ascorbic acid (>250 mg/day), excess consumption of vitamin C rich foods, iron supplements contain high concentration of vitamin C.
•Occult blood test results from the Hemoccult SENSA test cannot be considered conclusive evidence of the presence or absence of gastrointestinal bleeding or pathology. Hemoccult SENSA tests are designed for preliminary screening as an aid to diagnosis. They are not intended to replace other diagnostic procedures such as sigmoidoscopy, colonoscopy, barium enema, or other x-ray studies.
