The recommended screening procedure is three random stool specimens over a 5-7 day period. Amebas and certain other parasites cannot be observed in stools containing barium. Formed stools are more suitable for amebic cyst and helminth egg recovery. Soft or liquid stools (either normally passed or obtained by purgation) are more suitable for protozoan trophozoites. Specimens that do NOT arrive within 1 hour should be preserved so as to maintain the integrity of the parasites. Warning: Any stool collected by or from the patient may harbor pathogens which are IMMEDIATELY infective. Use extreme caution when Entamoeba histolytica, Hymenolepis nana, Strongyloides species, and Taenia species are suspected/reported.
