Table 3. Viral inactivation solution analytical equivalency study.
There was a 100% agreement with samples positive for SARS-CoV2 (with and without VIS) and a 100% agreement with sample negative for SARS-CoV2 (with and without VIS).
| Concentration of positive SARS-CoV2 RNA in saliva | Replicates | No VIS: Mean Ct (SD) | VIS Ct: Mean Ct (SD) | % Agreement | ||||
|---|---|---|---|---|---|---|---|---|
| N1 | E | RP | N1 | E | RP | |||
| 2x LoD | 10 | 28.3 (1.3) | 28.8 (1.3) | 22.6 (0.3) | 26.4 (3.3) | 27.8 (2.2) | 23.3 (0.5) | 100% |
| Negative (no viral RNA added) | 10 | n.d. | n.d. | 22.5 (.2) | n.d. | n.d. | 23.6 (0.4) | 100% |
Notes.
n.d. = not detected, cycle threshold growth curves do not cross the baseline before 40 cycles.
