CoNab with Delta variant
Use of CoNAb to Estimate NAb Level Against COVID-19 Delta Variant
- NAb titer against Delta variant is 1.2-2.8 folds lower than to wildtype virus by CoNAb Test (See the figure 7). This range matches the reports summarized by CDC (See the Figure 8).
- 75% neutralization against wildtype by CoNAb test = 50% neutralization against Delta variant by CoNAb System and corresponding to 1:100 NAb titer against Delta variant by cPass.
- NAb positive/negative Cutoff of CoNAb Test for Delta variant is ≥75%.
