Test Code VZIKS Zika Virus, PCR, Molecular Detection, Serum


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.



Specimen Required


Collection Container/Tube:

Preferred: Serum gel

Acceptable: Red top

Submission Container: Sterile container

Specimen Volume: 0.5 mL

Collection Instructions:

1. Within 2 hours of collection, centrifuge and aliquot the serum into a sterile container.

2. Serum specimens not aliquoted from the serum gel collection tube into a sterile container will be rejected.


Useful For

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

Testing Algorithm

The following algorithms are available:

-Assessment for Zika Virus Infection

-Mosquito-borne Disease Laboratory Testing

Method Name

Real-Time Reverse Transcription Polymerase Chain Reaction (RT-PCR)/DNA Probe Hybridization

Reporting Name

Zika Virus PCR, Serum

Specimen Type

Serum

Specimen Minimum Volume

0.25 mL

Specimen Stability Information

Specimen Type Temperature Time Special Container
Serum Refrigerated (preferred) 7 days
  Frozen  7 days

Reference Values

Negative

 

Reference values apply to all ages.

Interpretation

A positive test result indicates the presence of Zika virus RNA in the specimen.

 

A negative test result with a positive internal control indicates that Zika virus RNA is not detectable in the specimen.

 

A negative test result with a negative internal control is considered evidence of polymerase chain reaction inhibition or reagent failure. A new specimen should be collected for testing if clinically indicated.
