a Comparison of multiplex SONIA neutralization test for wild type against live wild type virus neutralizing assay (COVID-19 samples in purple diamond and controls in red square). b Comparison of multiplex SONIA neutralization test for delta against live delta virus neutralizing assay (COVID-19 samples in purple diamond and controls in red square). The vertical and horizontal dot lines are the cutoff of positivity for the live virus assay and the multiplex SONIA neutralization assay. The y-axis is the SONIA neutralization PCR test signal Δ\(\overline{{Ct}}\) calculated by subtracting the Ct value of the sample from that of a buffer only blank control.
