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.

Submit all specimens through the state health departments, NOT directly to the CDC or ARUP. CDC does not accept routine shipments on weekends or holidays. Therefore, ship to NPHL on Monday – Thursday, to guarantee arrival at the CDC by Friday.  
  Collection Device: See link above.
Specimen Labeling: Test subject to CLIA regulations and requires 2 patient identifiers and specimen source on container  
  Volume: See link above  

Prior to and during shipment:  Refrigerate 2-8°C.  Centrifuge and aliquot serum into sterile leak-proof tube, ASAP.  Place both CSF and serum at 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.
Refrigerate 2-8°C.

Place specimen inside leak proof secondary container (biohazard bag and if transporting by air, use Tyvek™ Envelope) with adsorbent material. The secondary container must be packed inside an approved Category B shipping container filled with frozen gel-packs to keep specimen refrigerated. Position NUlirt packing list or NPHL Test Order form between secondary container and box lid. Seal with tape.  Label outer 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). Follow appropriate DOT/IATA Regulation Guidelines.  For assistance, call NPHL State Training Coordinator at (402) 559-3590.

NUlirt packing list or appropriate paperwork (completed in entirety) must accompany specimens.

  Unacceptable: Severely lipemic, icteric or hemolyzed samples; heat-inactivated serum; multiple freeze thaw cycles  
  Specimen Stability: See link above  
  Reference Interval: NEGATIVE - No significant level of detectable virus RNA 
POSITIVE – Positive virus RNA detected  
  Reportable Disease: Report positive Dengue results as Arbovirus infection within 7d to local or state health department. Refer to Nebraska DHHS Title 173, Communicable Diseases.  
  Comments: Pre-approval needed from state or local health department.  Send approval to or call (402) 559-9444.
