Performance of the Abbott ID NOW rapid SARS-CoV-2 amplification assay in relation to nasopharyngeal viral RNA loads

•Calibration of the Xpert with viral stock dilutions was linear and reproducible.•Overall Xpert/ID-NOW positive agreement = 70% and negative agreement = 99.6%.•Sensitivity of ID-NOW for Xpert N2 CT ≤ 37 (viral loads ≥ 945 copies/mL) was 100%.•Sensitivity of ID-NOW for Xpert N2 for N2 CT > 37 was...
