- WNV, SuperQual® RT-PCR
Detect West Nile virus (WNV) RNA
• Mean detection: 74.3 copies/mL
• 95% detection cutoff: 281.6 copies/mL
SuperQual® polymerase chain reaction (PCR)
The direct detection of WNV is a valuable tool in determining whether a patient is infected with West Nile virus. PCR is able to detect WNV RNA directly and does not rely on antibody markers of WNV infection, which are produced after RNA is detectable in newly infected individuals.
Plasma, serum, or cerebrospinal fluid (CSF)
1 mL plasma or serum; or 0.5 mL CSF
0.5 mL plasma or serum; or 0.3 mL CSF
Frozen transport tube or plasma preparation tube (PPT™)
Collect blood in gel-barrier tube, yellow-top (ACD) tube, lavender-top (EDTA) tube, or plasma preparation tube (PPT™). Centrifuge blood at 800-1600xg at room temperature within one hour of draw to separate serum or plasma from cells. Transfer serum or plasma to a plastic screw-capped transport tube and freeze. Specimens drawn into PPT™ need to be centrifuged in a swinging bucket rotor centrifuge within one hour and frozen. Ship frozen. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
