What are the tests for respiratory syncytial virus infection?

Nasal mucous: Nasal mucous can be submitted to the lab for identification of the RSV antigen (protein) through immunoflorescent or enzyme immunoassay. These are available in kit form to hospitals & some offices.The test is seldom preformed unless the patient is hospitalized.The test itself does not predict the severity of illness but knowing test results simplifies supportive care as RSV is somewhat predictabl.
