Guaiac-based tests for occult blood in stool suffer from a number of drawbacks, leading to a reduction in their sensitivity as well as production of false-positive results. These drawbacks include: Detection of heme present in the stool, which can originate from bleeding anywhere in the gastrointestinal tract. Inability to distinguish human heme from heme present in many foods, such as dietary meats. Indiscriminate detection of peroxidase activity, which is present in a wide range of fruits and vegetables.
