Bingham, A., Cone, M., Mock, V., et al. (2016). Comparison of Test Results for Zika Virus RNA in Urine, Serum, and Saliva Specimens from Persons with Travel-Associated Zika Virus Disease Florida, 2016. Morbidity and Mortality Weekly Report. 65(18).
The Florida Department of Health Bureau of Public Health Laboratories conducted testing on samples from 913 persons who met the state criteria for testing. Test results for urine and serum samples showed that approximately twice as many urine specimens tested positive for Zika virus than serum specimens, suggesting that urine might be a more useful specimen for identifying acute Zika virus infection.
