Zika virus infection

Lab Bioterrorism Response & Special Pathogens Lab 401-222-5586
Organism Zika virus
Disease Zika
Test Description Trioplex PCR and Zika IgM MAC-ELISA. Testing performed is based on patient clinical history, specimen source and collection date. Serology may be performed on specimens collected >=4 days after symptom onset as well as on asymptomatic patients who are approved for testing. PCR is performed on serum and CSF specimens collected <=7 days after symptom onset as well as on urine collected < 14 days from symptom onset. Due to known cross reactivity among the flaviviruses, testing for Dengue and Chikungunya will also be performed on serum specimens from symptomatic patients. Specimens with positive or equivocal IgM results will be forwarded to CDC for PRNT.
Special Instructions Pre-approval for testing is mandatory. Medical provider must consult with the Department of Health Center for Acute Infectious Disease Epidemiology (401) 222-2577 if Zika virus infection is suspected.

Serum: collect blood in a serum separator tube, spin, pour off serum and submit >=1.0 ml in a sterile screw capped plastic tube.
