Admit Rapid Respiratory Flu RSV PCR



Rapid multiplex PCR for detection of Flu A, Flu B and Respiratory Synctial Virus (RSV).


This test provides rapid results to identify patients infected with Influenza A, Influenza B, or RSV.


See RapidViruPCR if testing for additional viruses.

See RapidBactPCR if testing for atypical bacteria.

Sample Requirements

Specimen: Nasopharyngeal (NP) Swab, Midturbinate (MT) Swab

Container: Universal Transport Media for NP/MT Swab

Preferred Vol: N/A

Minimum Vol: N/A


On-site collection: Please consult the Photo Swab Guide to determine which swab to collect. 

Off-site collection: Please consult the Photo Swab Guide to determine which swab to collect.
Note: This test is not performed at the Regional Clinics. If samples are received in the Regional Clinic, samples will be sent to Seattle Campus and results will be delayed. If the results are needed urgently, order the "Rapid Respiratory Virus PCR".



Note: Nasal Wash, tracheal aspirate, and bronchoalveolar lavage (BAL) in UTM are NOT FDA-cleared specimen types for Cepheid Flu/RSV PCR assay. Order "Rapid Respiratory Virus PCR" qualitative test for these samples.

Recent patient exposure to FluMist or other live attenuated influenza vaccines may cause inaccurate positive results.


This test is not intended to differentiate Influenza A subtypes or Influenza B lineages. If differentiation of specific influenza subtypes and strains is needed, additional testing, in consultation with state or local public health departments, is required.


Assay does not include Flu A suptype identification.
