Method Immunochromatographic Assay ICA, lateral flow test, rapid test
Turn-around Time 7 working days
  • The most common cause of false positive results is cross-reactivity with IgM specific for other flaviviruses.  
  • Negative results do not preclude infection with Zika and should not be the sole basis of a patient treatment/management or public health decision.
Common Causes for Rejection
  • Insufficient quantity
  • Unacceptable specimen type or source
  • Improper shipping conditions
  • Expired media or collection container
  • Discrepancies between specimen label and submission form
  • Incomplete, illegible, or missing submission form
Additional Information
  • Reactive samples will be forwarded to CDC for confirmatory testing by Plaque Reduction Neutralization Test (PRNT).
  • Minimum volume for CDC confirmation testing 0.5 mL.
