摘要: The performance of a commercially available, rapid membrane enzyme immunoassay for influenza A and B virus detection was compared to that viral culture in 4,092 respiratory specimens collected from patients presenting with symptoms during the 2002-2003 season. test's overall sensitivity 43.83%, lower than previously reported but similar both viruses (42.98 versus 44.76%). However, specificity, 99.74%, excellent (99.82 99.92%). These values make this test very good confirmatory when clinical suspicion is high, less accurate screening large populations.
