rose 6% after the company said its diagnostic test for influenza performed well in a recent study. The company's QuickVue influenza A+B test showed 96% sensitivity and 97% specificity in detecting "type A" influenza, the company said. The study was completed in Australia during flu season from July through September 2005. "The high clinical accuracy of the QuickVue test to detect type A influenza is especially significant in that the type A influenza viruses are most commonly associated with epidemics and pandemics, such as the one which occurred in 1918," the company said.
In separate studies during the 2004-05 flu season in Hong Kong and Japan with in vitro cultured virus, the company's test was able to detect the H5N1 virus, which causes avian flu, Quidel said. "Now that we know the QuickVue Influenza A+B test can detect H5N1 and other avian influenzas that have been cultured in vitro, we are committed to working with public health officials worldwide to determine how we can contribute to enhancing both human and avian influenza surveillance," the company said.
