Specimen Info
Only 1 specimen type required, unless otherwise specified
Volume: 2g solid or 2 mL liquid stool
Temperature: Ambient
Tube Type: Stool
Collection Info:
Minimum Volume: 2 g, 2 mL stool in formalin portion of O&P transport kit
Container: O&P transport vial with formalin (Para-Pak® pink) (preferred); sterile screw-cap container or Para-Pak® white
Collection: 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. The following recommendations are made for efficient and cost-effective diagnosis of diarrheal disease in patients admitted with gastroenteritis. • Submit one or two specimens per diarrheal illness immediately. Consider first requesting the EIA for Giardia and Cryptosporidium (see test Cryptosporidium, Direct Detection EIA [183020] or panel Giardia lamblia, Direct Detection EIA and Cryptosporidium, Direct Detection EIA [183558]. Giardia and Cryptosporidium are the most common causes of parasitic gastroenteritis in the United States. • If EIAs are negative, request add-on testing for Ova and Parasites Examination [008623] and submit an additional stool specimen after five days for O&P examination. • Also consider testing for unusual stool pathogens (Cyclospora Smear, Stool [183145]), especially in the immunocompromised patient.
