BCH Order Code WNVBL West Nile Virus, RNA, PCR, Molecular Detection, Blood


Specimen Required


Container/Tube: Lavender top (EDTA)

Specimen Volume: 1 mL


Useful For

Rapid testing for West Nile virus (WNV) RNA (lineage 1 and lineage 2)

 

An adjunctive test to serology for detection of early WNV infection (ie, first few days after symptom onset)

 

Blood may provide greater sensitivity for polymerase chain reaction detection of WNV RNA than other sources.

 

This assay should not be used for screening asymptomatic individuals and should only be used to test patients with signs and symptoms of WNV disease.
