This test is NOT appropriate for test of cure. Following treatment, the patient can be re-tested by submitting stool for culture (C STOOL), or appropriate EIA Stl Protozoa orderable.


This test should not be ordered more than ONCE per episode of diarrhea (at least 1 week between collections).



Sample Requirements

Specimen: Liquid or unformed stool collected in a clean leak-proof container is the optimal sample type. Rectal swabs are not optimal. In rare situations, exceptions may be made by contacting the Microbiology Lab 7-2585. Swab samples should be inserted at a distance sufficient to have visible stool on the swab (usually requires insertion of swab several centimeters into the rectum). Use the white capped E Swab System for collection.

Container: Clean leak-proof container


Preferred volume: 1 gram or ml


Minimum volume: 0.5 gram or ml


Processing Instructions

CPA: Send stool to Microbiology ASAP. If sample is shared and only one tube, syringe, or other container is received, affix shared sample label and send entire sample plus requisition to Microbiology. Please call Microbiology with sample related questions.


Off-Site Locations: This testing is only performed at SCH Microbiology. For satellite locations, the sample should be refrigerated prior to and during transport to the SCH Micro lab. Refer to stability requirements.
