ZIKV Fluorescent neutralization test validation.

<p>A total of 226 serum samples, among then negative and positive for flavivirus and non-flavivirus infections were examined. The neutralization titers that inhibit 90% of viral infection (NT₉₀) are shown in the graph. Other infections: Leptospirosis, CMV, EBV, Hantavirus, Toxoplasmosis, VDRL. Dashed lines represent the test cut off: negative when NT₉₀ <10, inconclusive when NT₉₀ ≥10 and <20, and positive when NT₉₀ ≥20. Symbols in blue indicate paired samples.
