Alphabetical Test listing

Pediatric COVID/FLU/RSV panel-14423

September 28, 2021

Due to supply disruptions, the standard turnaround time (TAT) for RSV and influenza testing is currently extended.

For the next several weeks, until the supply disruption issue is resolved, turnaround times for RSV and influenza testing is expected to be between 24 and 48 hours.

Please note that the COVID result will be reported as a preliminary result in alignment with the stated COVID TATs.

  • SARS-CoV-2
  • Influenza A
  • Influenza B
  • Respiratory syncytial virus (RSV)
  
  • The order of the Pediatric COVID/FLU/RSV panel is restricted to patients under the age of 6.
  • Performance of the Xpert Xpress SARS-CoV-2-Flu-RSV has only been established in nasopharyngeal swab specimens. Specimen types other than nasopharyngeal swab may give inaccurate results.
  • A false negative result may occur if a specimen is improperly collected, transported or handled.  False negative results may also occur if inadequate numbers of viral organisms are present in the specimen.
  • As with any molecular test, mutations within the target regions could affect primer and/or probe binding resulting in failure to detect the presence of virus.
  • Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease.
  • Negative results do not preclude infection and should not be used as the sole basis for treatment or other patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information.
  
Nasopharyngeal swab (flocked)
  
  

Use the mini-tip NP swab included in the COVID-19 test kit.

  1. Nasopharyngeal (NP) swab collection:

    1. Tip the patient’s head back.
    2. Gently insert the NP swab into the nostril parallel to the palate (not upwards) until resistance is encountered or the distance is equivalent to that from the ear to the nostril of the patient, indicating contact with the nasopharynx.   
      1. If any resistance is met in the passageways, do not force the swab; back off and try reinserting it at a different angle, closer to the floor of the nasal canal, or try the other nostril.
    3. Gently rub and roll the swab for 10-15 seconds while the swab is in contact with the nasopharyngeal wall.
    4. The CDC recommends leaving the swab in place for several seconds to absorb secretions.
    5. Slowly remove the swab and place in the transport medium.
    6. Break the swab shaft so that it fits into the medium container and recap tightly.
    7. Label the specimen appropriately. Document the source “NP” on the label.
