This test is a rapid test that detects the presence of infectious agent in nasal secretions and displays a visible result. To administer the test a sample is taken using a swab specific to nasal sampling, which is the narrower of the swabs provided. The padded end of the swab is inserted into a nostril approximately 1 to 1.5 cm and spinning it in place. This test has been proven effective by extensive testing of samples that have been identified as positive or negative by an alternate accepted diagnostic method. Performance of these tests are reported as measurements of Sensitivity, the ability to correctly identify a positive sample as positive, and Specificity, the ability to correctly identify a negative sample as negative. Further testing has been performed to ensure no cross-reactivity with infectious agents other than those specifically targeted. For influenza testing, the device is assessed annually against currently circulating strains to ensure they are still detectable.
