Collection: Sputum: If paragonimiasis or echinococcosis is suspected, submit specimen in 10% formalin. Feces: Submit in a parasite preservative kit. Please inoculate both the PVA and the formalin tubes. Fresh feces should not be submitted. State the preliminary diagnosis. Other: Contact the laboratory for specific instructions. All: Multiple specimens may be necessary to recover ova or trophozoites. Three specimens are recommended (each is charged). Fecal specimens for parasitic examination should be collected before initiation of antidiarrheal therapy or antiparasitic therapy. The highest yield on hospitalized patients occurs when diarrhea is present on admission or within 72 hours of admission. The onset of diarrhea more than 72 hours after admission is usually caused by Clostridium difficile toxin rather than parasites or the usual stool pathogens.
