West Nile Virus RNA, Qualitative Real‑Time PCR, Miscellaneous
Use
This laboratory‑developed molecular diagnostic test employs real‑time polymerase chain reaction (PCR) for the qualitative detection of West Nile virus RNA. It is intended for clinical use in patients suspected of active West Nile virus infection, particularly early in the disease course when viral RNA may be present in CSF, serum, or plasma. The test is not intended for screening asymptomatic individuals.
Special Instructions
Not provided.
Limitations
Not FDA cleared or approved; performance characteristics were determined by Quest Diagnostics and validated under CLIA regulations. Results reflect qualitative detection only (Detected/Not detected); negative results do not rule out infection — particularly if specimen is collected late or viral load is low. Interfering substances (e.g., specimen type or improper handling) may impact results.
