As with any occult blood test, results obtained with the OC Light S-Fit iFOBT should not be considered conclusive evidence of the presence or absence of G.I. bleeding or pathology. OC Light S-Fit iFOBT is designed for preliminary screening. It is not intended to replace other diagnostic procedures such as colonoscopy or sigmoidoscopy in combination with double contrast barium x-ray.

Urine and excessive dilution of samples with water from the toilet bowl may cause erroneous test results. For best results, use the collection paper in the collection kit.

OC Light S-Fit iFOBT is not for use in testing urine, gastric specimens or other body fluids.
