Preferred Specimen
NASOPHARYNGEAL SWAB IN UNIVERSAL TRANSPORT MEDIA

72 hours
Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)

Limitations
This test detects both viable and non-viable influenza A and B. Test performance depends on the amount of antigen in the specimen and may not correlate with virus culture results. A negative result may occur if the level of antigen in a sample is below the detection limit of the test. Positive test results do not rule out co-infections with other pathogens, and do not identify specific influenza A virus subtypes. Individuals administered nasal influenza A vaccine may have a positive test result up to three days after vaccination.
Clinical Significance
Immunofluoresence test allowing the differential detection of influenza A and influenza B antigens.
