Donor, West Nile Virus, NAT
Test Code19412
CPT Codes
87798
Preferred Specimen
6 mL plasma collected in an EDTA (lavender-top) tube
Minimum Volume
3 mL
Instructions
Label the tubes according to your standard operating procedure, making sure that each tube has at least two unique patient identifiers.
If transport temperatures will be frozen, centrifuge the lavender top tube and transfer the plasma into a plastic screw-cap vial. The plastic screw-cap vial (aliquot tube) containing plasma must be labeled with the specimen type (plasma) and at least two unique patient identifiers. Aliquot tubes must be processed and labeled at the original collection site. If aliquot tubes are submitted, do not send the original lavender top tube.
Please note: This test is to be used for the screening of DONORS of human cells, tissues, and cellular and tissue-based products for infectious diseases.
For Shipper collection please see detailed instructions in Test Resources.

Clinical Significance
The Procleix® WNV Assay is a qualitative in vitro nucleic acid assay system for the detection of West Nile Virus (WVN) RNA in plasma specimens from individual human donors, including volunteer donors of whole blood and blood components, and other living donors. It is also intended for use in testing plasma specimens to screen organ donors when specimens are obtained while the donor's heart is still beating. The assay is intended for use in testing individual donor samples. This assay is not intended for use as an aid in the diagnosis of West Nile Virus infection. It is not intended for use on cord blood specimens.
