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.

|
Reference Interval: |
NEGATIVE - No significant level of detectable dengue virus RNA
POSITIVE – Dengue 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 NPHL@unmc.edu or call (402) 559-9444.
Documentation must accompany the specimen to include the following information: symptoms and date of onset, pregnancy status, travel, and vaccine history.
During the first 7d of these illnesses, viral RNA can often be identified in serum, and RT-PCR is the preferred test for all chikungunya, dengue and Zika viruses. Refer to Dengue Fever Virus Antibody IgM test for specimens collected after 7d.
NUlirt packing list or appropriate paperwork (completed in entirety) must accompany specimens.
Test performed at the CDC branch in Ft Collins CO under Arbovirus. Submit all specimens for CDC through the NPHL, NOT directly to the CDC.
