  Test: West Nile Virus RNA Detection, Other Specimens 
  Synonym:  
  Method: Real-Time DNA Amplification 
  Availability: Daily 
  Specimen: CSF 
  Collection Device: CSF in a sterile tube 
  Volume: 0.5 mL 
  Storage/Transport: Refrigerate 
  Unacceptable:  
  Specimen Stability:  
  Reference Interval: Negative, virus not detected 
  Reportable Disease:  
  Comments: This test was designed to evaluate a select patient population in the acute phase of disease prior to the production of antibody and for those patients whose ability to develop an antibody response may be compromised due to underlying health conditions. Clinical studies have demonstrated that virus is no longer detectable after two days of symptoms. However, after three days of becoming symptomatic, IgM can be detected in the CSF of the majority of patients. This test detects RNA from West Nile virus but may also cross-react with other flaviviruses, including St. Louis Encephalitis virus. 
  Revised: 7/12/2011
