Clinical Significance
The Influenza A (H5) Virus RNA, Qualitative Real-Time PCR is a qualitative multi-target molecular diagnostic test that aids in the detection of the Influenza A H5 virus, including H5N1, commonly known as Avian Influenza. This test does not detect Influenza B or other respiratory viruses. This test is intended to be performed on respiratory specimens collected from individuals suspected of infection with Influenza A H5, or who meet the Centers for Disease Control and Prevention (CDC) clinical and/or epidemiological criteria for Influenza A H5N1 testing.
