New test extends window for accurate detection of Zika

(Columbia University's Mailman School of Public Health) Diagnosis of Zika infection is complex. Molecular tests for exposure are only reliable in the first two to three weeks after infection. Antibody tests are confounded by cross-reactivity of antibodies to Zika with similar viruses like dengue and yellow fever. A new blood test called ZIKV-NS2B-concat ELISA is faster, less expensive, and extends the window of accurate detection to months after onset of infection, giving clinicians a powerful tool to screen for Zika throughout pregnancy.
