Clinical Significance
This test is for detection of Influenza A virus, with reflex to H5 typing. The H5 reflex is a qualitative molecular diagnostic test performed on Influenza A positive samples to identify Influenza A H5 virus, including H5N1, commonly known as Avian Influenza. The reflex test does not subtype for seasonal influenza viruses. This test is intended to be performed on conjunctiva 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.

Laboratory test results should always be considered in the context of clinical observations and epidemiological data in making a final diagnosis and patient management decisions.
