Bordetella pertussis DNA Detection  

IMPORTANT! Pre-approval needed from state or local health department. Local or State Health Department. Send approval to or call (402) 559-9444.

NPHL has moved to an electronic ordering system, NUlirt, and it is now the preferred method to order all tests. Once ordered, print a "batch list" (see NUlirt Guide).

Forms Required - Nulirt batch list or NPHL Test Request Form (completed in entirety) must accompany the specimen to include the following information: symptoms and date of onset, pregnancy status, travel and vaccine history. Testing will not be performed without all required information.

Please call NPHL Client Services at (402) 559-2440 or toll free at (800) 334-0459 for further clarification.

Prior to and during shipment:  Refrigerate 2-8°C 
Shipping instructions, including specimen-handling requirements during transport:  Seal screw-top tubes with Parafilm™ or tape and place in biohazard bag with absorbent material.
Ship in insulated box on frozen gel-packs. Place packing list or other paperwork on top of Styrofoam and lid. Mark out rigid box as UN3373 Category B, Biological Substance. Transport by NPHL ground courier. If courier not available, ship by FedEx, UPS or USPS (1st Class, Priority or Express Mail).

See instructions and shipping address:
NUlirt packing list or appropriate paperwork (completed in entirety) must accompany specimens.

Unacceptable: Calcium alginate and Charcoal swabs are unacceptable.  Avoid specimens collected with a bacterial culturette swab used traditionally for Beta strep throat screens.  Use swab provided wtih UTM packaging.  
Specimen Stability: Stable at Refrigerated temperature 2-8°C for up to 7d post collection  
Reference Interval: Negative for Bordetella pertussis  
Reportable Disease: Positive results are reported to local or state health department. Refer to Nebraska DHHS Title 173, Communicable Diseases.  
Comments: A laboratory confirmed case is present if the specimen is PCR positive for pertussis. Culture confirmation of pertussis for at least one suspicious case is recommended any time there is suspicion of a pertussis outbreak. PCR has optimal sensitivity during the first 3 weeks of cough. PCR testing after 5 days of antibiotic use however is unlikely to be of benefit and it not generally recommended.
B. pertussis is the causative agent of whooping cough, while B. parapertussis causes a similar clinical illness characterized by milder symptoms and a shorter symptom duration. Detection of Bordetella can be difficult, particularly later in the clinical course. In order to detect B. pertussis with high analytical sensitivity, the test targets IS481, which is present in large numbers in B. pertussis. IS481 is also present in B. holmesii and some B. bronchiseptica strains, so cross reactivity amongst these species may occur. B. holmesii and B. bronchiseptica are uncommon human pathogens
