WebThe Xpert assay showed higher sensitivity for FluA (100% vs. 89.8%) and FluB detection (100% vs. 95.3%), and also higher accuracy (98.9% vs. 95.7%) for FluA than the CDFA-PCR. The positive and negative predictive values (NPV) for the three viruses ranged from 90.5% to 100% in the two assays, with higher NPV for FluA and FluB in Xpert assay. WebTest sensitivity was poorest using RT-PCR as a reference standard and highest using immunofluorescence (74% versus 88%; P < 0.001). Industry-sponsored studies reported significantly higher sensitivity (87% versus 78%; P = 0.01). Our results suggest that the poor sensitivity of RSV RADTs in adults may preclude their use in this population.
