Limitations

Results can only be regarded as preliminary screening or as an aid to diagnosis and cannot be considered conclusive evidence of the presence or absence of gastrointestinal bleeding or pathology. Certain medications may cause gastrointestinal irritation leading to occult bleeding. This may be a false positive test result.  A negative result can be obtained even when a GI disorder is present as not all polyps or colorectal cancers bleed or may bleed intermittently.
