The practical diagnostic value of fecal analysis in the evaluation of patients with chronic nonbloody diarrhea is controversial. It is possible that variations in its value depend on how it is done and how the results are interpreted rather than on its intrinsic value. In the authors' city, stool analysis has been made easily accessible, with a commitment to quality assurance and interpretation. To evaluate its practical value, the results of stool analysis obtained on stool specimens submitted by gastroenterologists were retrospectively reviewed. The results indicate that stool analysis has substantial practical diagnostic value in patients with chronic diarrhea.
