Culture; isolation and identification by fluorescent antibody staining (additional charges/CPT code[s] may apply). CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed. Requests with only a written order and no test number indicated will be processed according to Default Testing for Routine Microbiology.
The request form must state evaluate for Bordetella pertussis.
Expected Turnaround Time
13 - 16 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.
For more information, please view the literature below.
Nasopharyngeal (NP) swab
Flexible swab and special charcoal-containing Bordetella transport media (available from laboratory).
Guide the flexible swab into the contour of the nares and into the nasopharynx. Pass the swab gently through the nose. Leave swab in place near septum and floor of nose for 15 to 30 seconds. Rotate and remove. Place into special transport media available from the laboratory.
If possible, preincubate at 37°C; then use refrigerated temperature (2°C to 8°C) for transport.
Patient must not be on antimicrobial therapy.
Causes for Rejection
Unlabeled specimen or name discrepancy between specimen and request label; prolonged delay in transport (usually more than 72 hours); inappropriate specimen transport device (eg, noncharcoal-containing transport medium)
Isolate and identify B pertussis and B parapertussis; establish diagnosis of whooping cough
Nucleic Acid Amplification (NAA/PCR) procedures provide more rapid results and have been increasingly used in the diagnosis of B pertussis infection. Studies have shown that the best yield is obtained when PCR and culture are used to diagnose this infection.
