RSV is most commonly diagnosed with commercially available antigen assay tests, typically ordered as an RSV enzyme immunoassay (RSV-EIA). This test requires a nasopharyngeal aspirate or lavage sample, often obtained in the physician office or emergency department. The test is a rapid screen and is usually reliable—but a negative RSV-EIA does not rule out RSV.
