Performance of the QuickVue Influenza A+B rapid test in comparison with RT-PCR in the diagnosis of pandemic H1N1 (2009) virus infection.a
Figure 1.
Ct values of respiratory specimens in 119 patients with RT-PCR-confirmed pandemic influenza A H1N1 (2009) virus infections.
Ct values are compared between patients who had positive (Ct median 28.44) and negative (Ct median 31.9) results in the QuickVue Influenza A+B rapid test (p<0.001). The box shows the median and interquartile range (box length). The whiskers represent minimum/maximum values. Individual values are presented as circles.
Figure 2.
The numbers of specimens with a positive RIDT result were determined within four intervals of cycle threshold (Ct) values: 20.3–27.1, 27.2–30.3, 30.5–34.8, 34.9–41.6 (quartiles of Ct values).
