Bacteriology/Virology Section
Specimen(s):
FecalSwabs, Stool
Specimen Instructions:
For patients with community-acquired diarrhea of <7 days' duration WITHOUT warning signs (fever, bloody diarrhea, severe abdominal pain, dehydration, hospitalization, or immunocompromise) testing is not generally indicated unless diarrhea persists.

For persistent diarrhea >=7 days' duration, travel-related diarrhea or diarrhea with warning signs or risk factors for severe disease (see above), the gastrointestinal PCR panel should be ordered. If negative, consider additional diagnoses such as a full O&P panel (three samples over 10 days) in patients with an appropriate travel history (Epic LAB8332).

For healthcare-associated diarrhea with onset after the third hospital day, and at least 3 loose stools per day, consider C. difficile testing, which is orderable separately as "C. difficile toxin screen", LAB8239.
Collection Medium:
Fecal Copan Collection Transport Swab (Hospital Stores #105117)
Minimum:
The Enteric Panel can only be performed from FecalSwab samples. If test of cure is needed for Salmonella, Shigella or EHEC, order Epic LAB8534, Test of Cure Stool Culture instead.

Please use FecalSwabs [Stores #105117]
1) Obtain a stool specimen in a clean pan or container. Stool specimens should not contain urine or water.
2) Holding FecalSwab shaft above the red breakpoint mark, insert the entire tip of the FecalSwab into the stool sample and rotate. Do not use FecalSwab as a spoon; rather, coat swab with a visible layer.
3) If visible stool is not coating the FecalSwab tip, reinsert until swab is coated.
4) Using swab and aiming tube away, mash and mix the stool sample against the side of the tube to suspend the sample.
5) Invert the tube several times to homogenize the sample and expose the sample to Cary Blair preservative fluid.
Rejection Criteria:
Stool not in FecalSwabs, Rectal swabs, GI aspirates.
Delivery Instructions:
Deliver to laboratory immediately after collection.
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Turn Around Time:
6 hours (upon receipt in laboratory)
Reference Range:
Not Detected
