Zika Virus Real-time RT-PCR
Zika Virus Real-time RT-PCR test is a real-time RT-PCR test intended for the qualitative detection of RNA from Zika virus in human plasma, serum or urine (collected alongside a patient matched serum or plasma specimen). Specimens are collected from individuals meeting Zika virus clinical criteria (e.g., clinical signs and symptoms associated with Zika virus infection) and/or Zika virus epidemiological criteria (e.g., history of residence in or travel to a geographic region with active Zika transmission at the time of travel, or other epidemiologic criteria for which Zika virus testing may be indicated). Health care providers are strongly encouraged to collect serum/plasma specimens alongside other specimen types to provide additional opportunities for diagnosing Zika virus infection in cases when PCR tests are negative.
ProcedureExtraction of Zika virus nucleic acid from specimen, followed by combined reverse transcription of viral RNA and PCR amplification using real-time, RT-PCR methods. An internal control is added to ensure that extraction was performed correctly and that the RT-PCR reaction was not inhibited. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration. This test has been authorized by FDA under an EUA for use by authorized laboratories. This test has been authorized only for the detection of RNA from Zika virus and diagnosis of Zika virus infection, not for any other viruses or pathogens. This test is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of in vitro diagnostic tests for detection of Zika virus and/or diagnosis of Zika virus infection under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner.
SpecificityZika Virus RT-PCR does not cross-react with other viruses in the Flaviviridae family (including Dengue virus, Japanese encephalitis virus, West Nile virus and St. Louis encephalitis virus) or with other viruses known to cause similar clinical symptoms such as Chikungunya virus.
18 - 24 hours from receipt of specimen, Monday through Saturday.
