Diarrhea in Healthy Pediatric Patients Testing Algorithm

Diarrhea may be infectious or noninfectious and presents with acute (<14 days) or persistent (>14 days) symptoms. In most healthy pediatric patients, rehydration is a sufficient response to diarrhea. If testing is indicated, an initial workup may include viral testing, a bacterial stool culture, a parasite panel, and/or Clostridium difficile testing, depending on the clinical setting and any known exposures.
