Optimisation of the quadrivalent un-labelled competitor homologue DV NS1quench. Sample /cut off ratios are shown for both the G capture assay and the DABA. The sample reactivity unquenched and quenched at the three levels of 25, 12.5 and 6.25μg/ml is shown for each assay, samples still reactive in the presence of conjugate quenching are displayed in bold. Reactivity of the control ZIKA-positive samples is displayed (bottom four rows).
