Fig. 2 — Analysis of sensitivity and specificity using prospective gathered nasopharyngeal samples (grey dots) and QCMD samples (white dots). Crossing point (Cp) values of single target assays (i.e. singleplex) are plotted against Cp values of multiplex analysis, for every individual virus species. Dots with a Cp > 40 represent discrepant PCR results (i.e. sole detection by one of the assays).
