Real-Time PCR testing for Zika Virus, Chikungunya Virus, and Dengue Virus by the CDC Trioplex rRT-PCR Assay, verified for use under Emergency Use Authorization by the FDA.
ELISA (Enzyme-Linked ImmunoSorbent Assay) IgM serology testing for Zika (verified for use under Emergency Use Authorization by the FDA), Chikungunya, and Dengue
Molecular and Virology
PCR and IgM Serology testing is done in accordance with CDC guidelines for laboratories testing for Zika Virus.
CDC lab guidance: http://www.cdc.gov/zika/laboratories/lab-guidance.html
Note: Testing for Zika, Chikungunya, and Dengue is available only after consultation with the Bureau of Communicable Disease Control and Prevention at (573) 751-6113 or after hours 800-392-0272.
Zika collection kit contains one (1) red-top blood collection tube, one (1) urine collection cup, parafilm for sealing urine cup, and two (2) freeze pillows.
PCR and/or IgM Serology:
- Collect a serum and urine specimen from all patients. NOTE: URINE MUST ACCOMPANY A PATIENT-MATCHED SERUM. Testing cannot be performed if only a urine specimen is submitted.
- Collect blood in a red top or marble-top (serum separator) Vacutainer tube. Centrifuge the blood and transfer the serum to a new red top or other sterile tube. At least 1 ml of serum is required for PCR and serological testing. At least 1 mL of urine is required for PCR testing.
