|||
|---|---|---|---|---|
| E, N2, RdRp | E, N2 | N2 | E | |
| Xpert positive/SOC positive | 168/199 (84.4) | 29/199 (14.6) | 1/199 (0.5) | 1/199 (0.5) |
| Xpert positive/SOC negative | 5/11 (45.5) | 2/11 (18.2) | 1/11 (9.1) | 3/11 (27.3) |

Twelve specimens were inconclusive by the New York EUA method, and 21 specimens tested at Rutgers University Hospital are not included because the EUA version of the Xpert test was used (no RdRp target). Both E and N2 targets were detected by the Xpert EUA test in 10 of these specimens, and the N2 target alone and E target alone were each detected in 1 specimen.
