Rapid Diagnostic Testing For Clinical SyndromesDiagnostic Testing Performed During TravelSpecial ConsiderationsFuture DirectionsBibliographyRespiratory infections are among the most common travel-related diseases. Individual and multiplex tests using nasopharyngeal swab samples are widely available for influenza A, influenza B, and respiratory syncytial virus. The sensitivity of rapid antigen tests for influenza is notably poor; negative results should not dictate therapy decisions and should be confirmed with molecular testing. Influenza subtyping is primarily used for public health surveillance and is not commonly available with rapid testiSee more on wwwnc.cdc.govPeople also askWhat is NS1 testing?What is NS1 testing?NS1 tests detect the non-structural protein NS1 of dengue virus.
