Flavivirus Genus PCR

Test Code:



Specimen Container

​1) EDTA Tubes (at least 3 full tubes)
2) Sterile container without any media for urine, amniotic fluid and cerebro-spinal fluid (CSF).

Specimen Requirement

​During acute illness, especially when patients are still febrile, blood samples in EDTA (purple top) tubes(at least 3 fully-filled) is the sample of choice. For a number of flaviviruses (eg. dengue virus, Zika virus, yellow fever virus, Japanese encephalitis virus, West Nile virus, etc), viral RNA may remain detectable in the urine for prolonged periods of time after they are undetectable in the plasma. If clinically warranted, consider sending urine sample in addition for testing. Please note that such requests will be separately chargeable.

This assay has also been validated on urine, amniotic fluid and cerebro-spinal fluid(CSF) samples.
Please note that other sample types have not been validated on this new assay and will generally be rejected.

Specimen Storage / Transport

​Refrigerate sample at 2-8°C until transfer to laboratory. Do not freeze. Send sample at 2 - 8°C. Sample should reach the laboratory as soon as possible preferably within 24 hours after collection.
