Respiratory Pathogens Panel
Reviewed
Also called: Respiratory virus profile, Syndromic multiplex panel, Multiplex respiratory panel, Multi-pathogen molecular assay
A respiratory pathogens (RP) panel checks for viruses and bacteria in your respiratory tract using a single sample. It helps identify the cause of a serious respiratory infection, especially when you are hospitalized or at risk for complications. Results usually come in a few hours, allowing faster, targeted treatment.
Specimen: Nasopharyngeal swab or nasal aspirate
Why this test may be ordered
- You have symptoms of a respiratory infection and are seriously ill, hospitalized, or at risk for complications.
- To identify the specific virus or bacteria causing your infection so the right treatment can be started quickly.
- To help avoid unnecessary antibiotics (which do not work against viruses).
Preparation and collection
You don't need any special preparations for this test.
Your provider will collect a sample either by gently inserting a swab into your nostril (nasopharyngeal swab) or by squirting saline into your nose and removing the sample with gentle suction (nasal aspirate).
The swab test may tickle your throat or cause you to cough. The nasal aspirate may be uncomfortable or cause your eyes to tear. These effects are temporary.
Understanding results
Your provider will interpret your results along with your symptoms, medical history, and other test results. The following patterns are based on the information provided by MedlinePlus.
- Negative: No pathogen from the panel was found. Your symptoms may be caused by a pathogen not included in the panel, the sample may not have been collected correctly or was too small, or you may have a condition not caused by a virus or bacteria. Limitation: A negative result does not rule out all respiratory infections. Next step: Routine
- Positive for one or more pathogens: A specific pathogen (virus or bacteria) was found. If more than one is positive, you may have a co-infection. Limitation: The result tells you which type of infection you have but does not determine treatment on its own. Next step: Your provider will recommend treatment and/or order more tests (such as a bacteria culture, viral blood tests, or Gram stain) to confirm the diagnosis and guide treatment.
- The panel only tests for the specific pathogens included; a negative result does not rule out other causes.
- Sample collection errors (e.g., insufficient sample) can affect accuracy.
- Results must be interpreted by your healthcare provider along with your symptoms, medical history, and other tests.
What to do next
Based on your results, your provider will recommend treatment and/or order more tests. These may include a bacteria culture, viral blood tests, and a Gram stain. Talk to your provider if you have questions about your results.
- What specific pathogens does this panel test for?
- What do my results mean for my treatment?
- Do I need any follow-up tests?
