Message

For Specimen Integrity during Extreme Weather see the “Lockbox Usage in Extreme Weather” document at the top of this page.

Test Code

ZKAPCR

CPT Codes
87662 (x2)

Preferred Specimen

3 mL serum and 2 mL urine collected in an Aptima® urine collection kit

Minimum Volume

1.5 mL serum • 2 mL urine

Instructions

⁠⁠⁠⁠⁠⁠⁠Note: Both serum and urine, with the same collection date, are required for each patient.

Collect blood in a serum separator tube or a standard red-top, allow blood to clot at room temperature. The specimen should be centrifuged as soon as possible, and serum transferred to a new aliquot tube.

Urine should always be collected with a patient-matched serum specimen.

Urine: Direct patient to provide urine into a urine collection cup free of any preservatives. 2 mL of urine must be transferred into the Aptima specimen transport tube within 72 hours of collection and before being assayed. Use the tube provided in the urine specimen collection kit. The fluid (urine plus transport media) level in the urine transport tube must fall within the clear pane of the tube label.

Transport refrigerated (cold packs) to local quest accessioning laboratory.
Transport frozen (dry ice): If shipping directly to the performing laboratory by an overnight air courier. Specimens must not be left in lock bins.

Clinical Significance

This test is intended for the qualitative detection of Zika virus in serum and urine from individuals who meet the Centers for Disease Control and Prevention (CDC) clinical and epidemiological criteria for Zika virus testing. Zika viruses are primarily transmitted by Aedes aegypti and Aedes albopictus mosquitos [1].

Most individuals with a Zika virus infection are asymptomatic. Individuals with symptomatic infections may experience fever, rash, and muscle/joint pain [2].

Per the 2019 CDC guidelines, testing is recommended only for symptomatic pregnant women with a history of living in or traveling to a geographic area at risk for Zika. For current testing guidelines, see https://www.cdc.gov/zika/hc-providers/testing-guidance.html

For individuals meeting the CDC criteria, concurrent testing of serum and urine is recommended as soon as possible after symptom onset. Zika infection shares clinical and epidemiological features with other arbovirus infections such as Dengue and Chikungunya. For CDC guidelines on testing concurrently for Zika and Dengue, see https://www.cdc.gov/dengue/healthcare-providers/testing/testing-guidance.html
