Question

Quizplus · Accepted Answer

Fecal occult blood tests are used to test for blood that may be present in stool but cannot be seen by the naked eye (microscopic). This is usually indicative of a gastrointestinal bleed. All other options are incorrect. Detecting bright red blood, dark black blood, and blood that contains mucus (mucoid) is not the purpose of a guaiac test.
