To illustrate the reliability of the T-Track® SARS-CoV-2 interpretation algorithm, the distribution of the distance to the classification threshold was evaluated in samples of donors exposed to SARS-CoV-2 (through infection or vaccination) and not exposed to SARS-CoV-2 (naïve), in response to S1 or NP antigens (Figure 8). This evidence concerns the gene PSMD1 and infection.
