Culture
Result Turnaround Time
4 - 6 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
Culture for Yersinia only; isolation, identification (additional charges/CPT code[s]). CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed.
Use
Isolate and identify Yersinia enterocolitica only; susceptibility test is performed at an additional charge.
Special Instructions
Fecal specimens for different tests often need different transport containers. Specimens should be portioned out to separate devices of each type for each test requested before sending to the laboratory. Stool for bacterial culture should be submitted in the C&S transport vial, only a thumbnail size portion of stool, about 1 to 2 g or 1 to 2 mL of stool should be added to the vial. Overfilling the vial will reduce recovery of stool pathogens.
Specimen Requirements
Specimen
Stool or rectal swab placed in stool culture transport vial
Volume
1 to 2 mL or 1 to 2 g stool in stool C&S transport vial
Container
Stool culture transport vial (Para-Pak® orange) is required.
Collection Instructions
A single stool specimen cannot be used to rule out bacteria as a cause of diarrhea. It is recommended that two or three stool specimens, collected on separate days, be submitted to increase the probability of isolating a bacterial pathogen. Hospitalized patients who develop diarrhea while hospitalized and more than 72 hours after admission should be tested for Clostridium difficile by detection of either toxin A and/or toxin B.
Studies have shown that patients who did not have gastroenteritis or other GI symptoms on admission are unlikely to have diarrheal illness due to Salmonella, Shigella, Campylobacter, or enterohemorrhagic E coli.
Storage Instructions
Maintain specimen at room temperature.
Causes for Rejection
Specimen received in grossly leaking transport container; diapers; dry specimen; specimen submitted in fixative or additive; specimen received in expired transport media or incorrect transport device; inappropriate specimen transport condition (not in a C&S vial or in an overfilled C&S vial); specimen received after prolonged delay in transport (usually more than 72 hours); specimen stored or transported frozen; wooden shaft swab in transport device; unlabeled specimen or name discrepancy between specimen and request label
