Limitations

•    OC-Light® S FIT is intended only for the detection of human hemoglobin in feces. It is not advised for use in patients suspected of upper GI bleeding.
•    Patients with the following conditions should not be considered for testing as these conditions may interfere with the test results:
o    Bleeding hemorrhoids
o    Constipation bleeding
o    Urinary bleeding
o    Menstrual bleeding
•    Certain medications such as aspirin and non-steroidal anti-inflammatory drugs may cause gastrointestinal irritation and subsequent bleeding in some patients and cause positive results.
•    As with any occult blood test, results obtained with OC-Light® S FIT should not be considered conclusive evidence of the presence or absence of GI bleeding or pathology. It is not intended to replace other diagnostic procedures such as colonoscopy, sigmoidoscopy, and double contrast barium x-ray.
•    Because gastrointestinal lesions may bleed intermittently and blood in feces is not distributed uniformly, a negative test result does not assure absence of lesion.
•    Urine and excessive dilution of samples with water from the toilet bowl may cause erroneous test results. For best result, use Collection Paper. 
•    OC-Light® S FIT is not for use in testing urine, gastric specimens, or other body fluids.
•    Use of stool samples that are not collected in a provided sampling bottle following bowel movement may affect the result due to instability of Hemoglobin in stool.
•    Fecal occult blood testing is recommended annually by the American Cancer Society (2008) for average-risk women and men, 50 years of age and older. However, patients with significant risk factors such as family history of colorectal cancer should be screened earlier and more often.
