Comparison of quantitative antibody measurements (MFI) with reference serostatus in HHV species-specific Monoplex Serology.

I-Vb indicate corresponding reference panels. gE/gI: co-loading of antigens gE and gI onto one bead set red lines: optimized cut-offs for single antigen performance; cut-offs were determined by optimizing specificity and sensitivity. MFI: Median Fluorescence Intensity.
