Order Code VZIKU Zika Virus, PCR, Molecular Detection, Random, Urine


Ordering Guidance


Due to similar clinical presentations, testing for RNA or IgM-class antibodies to dengue and chikungunya viruses, concurrently with Zika virus testing, is strongly recommended.



Additional Testing Requirements


The US Food and Drug Administration requires that urine specimens be tested in conjunction with a paired serum specimen; order VZIKS / Zika Virus, PCR, Molecular Detection, Serum for the paired serum specimen.



Specimen Required


Container/Tube: Sterile container

Specimen Volume: 1 mL

Collection Instructions:

1. Collect random urine in a sterile container.

2. Label specimen as urine.


Useful For

Qualitative detection of Zika virus RNA in paired urine and serum from individuals meeting the Centers of Disease Control and Prevention Zika virus clinical or epidemiologic criteria

Method Description

The RealStar Zika Virus RT-PCR Kit by Altona Diagnostics is a TaqMan assay employing a reverse transcriptase (RT) reaction to convert RNA to complementary DNA, followed by polymerase chain reaction (PCR) amplification of specific target sequences and detection by target specific probes. Probes specific for Zika RNA are labelled with the fluorophore FAM. The kit also contains an internal control labeled with the fluorophore JOE. The internal control is added to the nucleic acid extraction procedure and undergoes RT and amplification in parallel to Zika virus-specific RNA that may be present in patient specimens. The different dye-labeled probes allow detection of Zika virus and the internal control simultaneously in corresponding detector channels of the LC 480 instrument. The test can be completed within 120 minutes following RNA extraction and is completed in a closed system.(Package insert: RealStar Zika Virus RT-PCR Kit US.
