Stool analysis, also called fecalysis or stool exam, is a series of tests done on the feces. Doctors often recommend fecalysis as a part of a routine check-up or because they suspect problems in the digestive system. The results can help diagnose a wide range of conditions, from infections, malabsorption to cancer. In the laboratory, the technician checks the stool’s color, odor, and content (mucus, blood, microorganisms, or blood cells). Since improper collection might affect the result, this article focuses on the stool specimen collection procedure.
