Epic Code LAB3618 Enteric Pathogens by PCR

Important Note

Stool specimen must be placed in Cary Blair Media immediately after collection, up to the fill line (approximately 5 mLs of LIQUID stool).

Test Name Alias

Enteric Pathogens by PCR | Stool Culture | 7122

Interface Order Alias

55078

Clinical Information

The qualitative nucleic acid test (utilizing reverse transcriptase PCR) detects genetic markers of common community-acquired pathogenic enteric bacteria, viruses from a stool sample, two to three days faster than current methods:

Note: All 3 vials of the stool kit should be filled to their line, do not overfill.

Always READ LABELS as container colors may differ based on manufacturer.

Collection Instructions

Specimen Type: Preserved Stool

Container/Tube: Cary-Blair Medium

Volume: Fill container to volume indicated on vial

Collection Instructions:

  • Collect liquid or soft stool preserved in Cary-Blair medium by using the manufacturer's recommended collection procedure to fill to the line indicated halfway up on the container.
  • Note: This panel may not be utilized as a test of cure and repeat testing will not be performed on samples collected <7 days apart.
  • Note: For small sample volume, remove some of the media and then add stool, trying to maintain the 1 to 3 ratio of stool to media. Make an order note in the Laboratory Information System that media was poured out before the sample was added.
  • Note: All 3 vials of the stool kit should be filled to their line, do not overfill. 

Specimen Transport Temperature: Ambient

Lab Staff Instructions

  • Cary-Blair preserved specimens to be stored refrigerated at 2 - 8°C until testing is completed (for up to 48 hours after collection)

Specimen Stability

Ambient: 48 hours

Refrigerate: 48 hours

Frozen: do not freeze

Laboratory Retention: 3 days

Test Frequency

The test is performed first and second shift at SHRL. Turn around time: 24 hours upon receipt in laboratory

Reference Range

Detects genetic markers of the following:
• Campylobacter Group (composed of C. coli, C. jejuni, and C. lari)
• Salmonella species
• Shigella species (including S. dysenteriae, S. boydii, S. sonnei, and S. flexneri)
• Vibrio Group (composed of V. cholerae and V. parahaemolyticus)
• Yersinia enterocolitica
• Norovirus GI/GII
• Rotavirus A


In addition, EP detects the Shiga toxin 1 gene and Shiga toxin 2 gene virulence markers. Shiga toxin producing E. coli (STEC) typically harbor one or both genes that encode for Shiga toxins 1 and 2.

 

If Aeromonas is a concern, call the Microbiology laboratory ahead of tme at 616-267-2640 and order Microbiology organism identification reference [LAB4003] in conjuction with ordering the Enteric pathogen panel.
