  • a The sensitivity of DFA was taken from the literature (6, 13, 17), where DFA was compared to at least one other test, including at least one molecular test, and where test performance was calculated by using a combined reference standard for positivity. The sensitivity of DFA plus SVC was set at 72%, which showed a 2% increase in the positive detection rate obtained in our laboratory during the study period when SVC was used. The sensitivity of the xTAG RVP test reflects the median sensitivity for 12 respiratory viruses detected by the xTAG RVP test (4). The specificity of each test was set at 98%.
