Test 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

Testing Algorithm

Due to US Food and Drug Administration requirements, urine specimens must be tested in conjunction with a paired serum specimen. See Additional Testing Requirements

 

The following algorithms are available:

-Assessment for Zika Virus Infection

-Mosquito-borne Disease Laboratory Testing

Reference values apply to all ages.

Interpretation

A positive test result indicates the presence of Zika virus RNA in the specimen. The FDA requires that urine specimens be tested in conjunction with a paired serum specimen. However, a positive result in either specimen is consistent with recent infection.

 

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.
