| Test Name/Synonym: | Bacterial Enteric Panel (Synonym: Stool Culture, Enteric bacterial panel, Bacterial diarrhea, gastroenteritis, Campylobacter, Salmonella, Shiga toxin-producing Escherichia coli, STEC, Shigella, Yersinia, Vibrio cholerae) | ||
| Test Includes: | Diarrheal stool specimens are screened using the BD MAX™ Enteric Bacterial Panel, a commercial polymerase chain reaction (PCR) assay that tests for Shiga toxin-producing Escherichia coli (STEC, including O157 and non-O157), Salmonella species, Campylobacter jejuni/coli, and Shigella species. Targeted culture is performed on all PCR-positive results. Culture results are reported as an Extended Bacterial Enteric Panel Culture. Culture testing for additional pathogens (Yersinia spp., Vibrio spp., or others) is only performed if additional clinical/exposure history is provided on the requisition/order:

| LABID (Connect Care): | LAB223 | ||
| Specimen Type: | Stool Swab | ||
| Specimen Source: | Stool Stoma Rectal | ||
| Primary Container: | 60 mL sterile, plastic container | ||
| Alternate Containers: | Calgary Zone (ACH/SHC sites) only: COPAN FecalSwab™ (for rectal swabs) Note: Rectal swabs must be collected using the COPAN FecalSwab™ and are only acceptable for pediatric patients with hematochezia and/or neurological sequelae of gastroenteritis (e.g. seizures). A stool specimen should still be submitted when available. | ||
| Specimen Collection Requirements: | Patient Collection Instructions: Stool collections for Bacterial Pathogens Stool must not be contaminated with urine, water or other contaminants. Do not use a laxative, antibiotics, anti-diarrheal drugs or enemas before collecting stool specimens. Note: If Ova and Parasite microscopic examination is also requested, a collection kit is required. Only submit one stool specimen initially, regardless of patient’s clinical circumstances. For hospitalized patients, testing will only be performed if symptom onset occurred within the first four days of admission. | ||
| Test Resources: | Order in Connect Care, or use Community Microbiology Requisition - 20571 | ||
| Stability and Storage: | Refrigerate | ||
| Method and Interpretation of Results: | PCR is more sensitive than culture. As PCR detects the presence of nucleic acid, PCR-positive but culture negative results may represent current infection, past/resolving infection, treated infection or colonization. As with all testing, false positive and false negative results may occur. Correlation with clinical picture is required | ||
