Clinical significance: 

The Zika Virus RNA, Qualitative, Real-Time RT-PCR is a real-time RT-PCR test intended for the qualitative detection of RNA from Zika virus in human serum collected from individuals meeting CDC Zika virus clinical criteria and/or CDC Zika virus epidemiological criteria. Test results are for the identification of Zika viral RNA. Zika viral RNA is generally detectable in serum during the acute phase of infection and up to 7 days following onset of symptoms, if present, or longer in a pregnant woman. A positive result provides evidence of Zika virus infection. Within the United States and its territories, positive Zika test results are reported, as required, to the appropriate public health authorities. Negative results do not rule out Zika virus infection and should not be used as the sole basis for patient management decisions.
