West Nile Virus (WNV) Molecular Detection

Synonyms

  • LAB11815
  • WEST NILE RT-PCR

Cerner Name

West Nile RT-PCR

Clinical Info

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.
