Intestinal biopsy is not required in evaluating an otherwise healthy child with acute-onset diarrhea, but it may be indicated in the presence of chronic or protracted diarrhea, as well as in cases in which a search for a cause is believed to be mandatory (eg, in patients with acquired immunodeficiency syndrome [AIDS] or patients who are otherwise severely immunocompromised).
