HelpTest Code Billings Clinic:5377 Mayo:BPRPV Bordetella pertussis and Bordetella parapertussis, Molecular Detection, PCR, Varies
Necessary Information
Specimen source is required.
Specimen Required
The high sensitivity of amplification by polymerase chain reaction (PCR) requires the specimen to be processed in an environment in which contamination of the specimen by Bordetella pertussis or Bordetella parapertussis DNA is unlikely.
Submit only 1 of the following specimens:
Preferred:
Specimen Type: Nasopharyngeal swab
Supplies:
Culture Swab - Liquid Stuarts/Single Swab (NP Swab) (T515)
Container/Tube: Rayon swab with an aluminum shaft placed in transport medium such as a green-top nasopharyngeal swab (rayon mini-tip) with Stuart's media (no charcoal), or Stuart's media with charcoal, or Amies media with or without charcoal (Transwab Nasopharyngeal with Charcoal System).
Additional Information:
1. Swab transport containers without charcoal must contain a pledget saturated with either Stuart's or Amies liquid media. Clear semi-solid/solid media is gel and will be rejected.
2. Other swab or media types may be inhibitory to PCR testing and will be rejected.
Acceptable:
Specimen Type: Nasopharyngeal (not throat) aspirate/wash or nasal aspirate/wash
Container/Tube: Sterile container with a screw top cap (no transport media)
Specimen Volume: Entire collection
Useful For
Preferred diagnostic test for the detection of Bordetella pertussis or Bordetella parapertussis
This test is not recommended for screening asymptomatic individuals who may carry B pertussis or parapertussis.
This test is not recommended for follow up of patients previously diagnosed with pertussis (ie, as a test of cure).

Interpretation
A positive result indicates the presence of DNA from Bordetella pertussis or Bordetella parapertussis. In some cases, a patient may test positive for both B pertussis and B parapertussis. Cross-reactivity with Bordetella holmesii and Bordetella bronchiseptica may occur with the B pertussis assay (see Cautions).
A negative result indicates the absence of detectable B pertussis and B parapertussis DNA in the specimen but does not negate the presence of organism or active or recent disease (known inhibition rate of <1%) and may occur due to inhibition of polymerase chain reaction, sequence variability underlying primers and/or probes, or the presence of B pertussis or B parapertussis in quantities less than the limit of detection of the assay. Additionally, patients presenting late after symptom onset may test negative; in such cases, testing for B pertussis antibody, IgG, in serum (BORDG / Bordetella pertussis Antibody, IgG, Serum) may be considered.
