Frozen: Unacceptable




Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
The laboratory accepts one stool specimen per day, per patient, for culture, additional submissions will not be processed.
Specimen received on a diaper or scraped from a diaper are unacceptable.
Rejection will occur for the following reasons: improperly labeled specimen, insufficient volume, specimen not submitted in appropriate transport container


Methodology
Standard culture methodology for detection of Salmonella and Shigella. ImmunoCard STAT EHEC for detection of Shiga Toxins 1 and 2. ImmunoCard STAT CAMPY for detection of Campylobacter antigens.


Setup Schedule
Daily


Report Available

Shiga Toxin and Campylobacter antigen final result within 2 days, Salmonella and Shigella culture results typically 3 days (but may vary depending on the necessary workup)




Limitations

Delayed transportation to the laboratory or inappropriate transportation conditions may result in decreased viability of stool pathogens. Rule out of additional bacterial pathogens requires notification of the laboratory or additional test ordering prior to sample submission. These organisms may require special growth media and separate orders and may include: Aeromonas, Vibrio, Yersinia, Plesiomonas, Staphylococcus, Pseudomonas (See clinical significance section for test codes




Reference Range
Negative for Salmonella, Shigella, Campylobacter, Shiga Toxin


Clinical Significance
Interpretation: Growth of a pathogen suggests an infectious cause of diarrhea. Diarrhea may be caused by a number of pathogens and other factors. Potential Accompanying Tests For This Source include: Yersinia-Stool Culture (CXYER), Vibrio-Stool Culture (CXVIB) and Aeromonas/Plesiomonas- Stool Culture
