Result Turnaround Time
14 - 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.
Test Includes
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.
Use
Isolate and identify B pertussis and B parapertussis; establish diagnosis of whooping cough
Special Instructions
The request form must state evaluate for Bordetella pertussis.

Custom Additional Information
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.

Specimen
Nasopharyngeal (NP) swab
Volume
One swab
