Influenza tests detects the presence of the virus in a sample of respiratory secretions. Influenza (the flu) is a common viral respiratory infection that causes an illness ranging from mild to severe, and sometimes can be fatal.
A positive flu test means that the affected person most likely has influenza A or B, and treatment with antiviral medication may be prescribed to minimize symptoms.
A negative influenza test may mean that the person has something other than influenza, that the test is not detecting the influenza strain, or that there is not sufficient virus in the specimen to allow it to be detected.
