Respiratory Pathogens Panel

A respiratory pathogens (RP) panel is a diagnostic test used to identify specific viruses or bacteria causing a respiratory infection.

Overview

A respiratory pathogens (RP) panel checks for pathogens—viruses, bacteria, or other organisms—in your respiratory tract, which includes your lungs, nose, and throat. While many respiratory infections resolve with rest and fluids, identifying the specific cause can help determine the best treatment and avoid unnecessary use of antibiotics.

What is it used for?

The panel tests for a variety of pathogens, which may include:

  • Viral infections: Flu, common cold, respiratory syncytial virus (RSV), adenovirus, and COVID-19.
  • Bacterial infections: Whooping cough and bacterial pneumonia.

Why do I need this test?

Your provider may order an RP panel if you are seriously ill, hospitalized, or at risk for complications. Symptoms of a respiratory infection include:

  • Coughing
  • Trouble breathing
  • Sore throat
  • Stuffy or runny nose
  • Fatigue
  • Loss of appetite
  • Fever

Procedure

Samples are collected via one of two methods:

  • Nasopharyngeal swab: A swab is inserted 1 to 2 inches into the nostril until it reaches the top of the throat, then rotated.
  • Nasal aspirate: Saline solution is squirted into the nose and removed with gentle suction.

Understanding Results

  • Negative result: No pathogens included in the panel were found. This may mean the illness is caused by a pathogen not tested for, or the sample was insufficient.
  • Positive result: A specific pathogen was identified. If multiple parts of the panel are positive, it indicates a co-infection.

Prevention

To help prevent the spread of respiratory infections, practice frequent handwashing, use alcohol-based hand sanitizer, disinfect surfaces, and stay up to date on recommended vaccinations, such as the flu shot and COVID-19 vaccines.

Frequently Asked Questions

Results for many respiratory panels are available within 24 to 48 hours, though some specific bacterial cultures may take longer. In many cases, treatment for viral infections is supportive and does not change based on the specific virus identified. However, identifying a bacterial cause like whooping cough or specific pneumonia can lead to targeted antibiotic therapy, which is why the test is often ordered for hospitalized or high-risk patients where precise diagnosis impacts medication choices.
The nasopharyngeal swab can cause mild discomfort, such as sneezing, gagging, or a brief scratchy sensation in the throat, but it is generally not painful. For infants and young children who may struggle with the swab, providers often use a nasal aspirate, which involves gently suctioning a small amount of fluid from the nose, or a simple nasal swab, depending on the specific pathogens being tested and the child's age and cooperation level.
negative result indicates that none of the specific viruses or bacteria included in that particular panel were detected in your sample. This does not rule out a respiratory infection, as the panel may not test for every possible pathogen, or the viral load may have been too low to detect at the time of sampling. Your provider will likely rely on your clinical symptoms and may order additional tests or treat based on clinical judgment rather than a specific pathogen identification.
False positives are possible but relatively rare with modern PCR-based panels. They can occur due to cross-reactivity with similar genetic sequences from other organisms or, less commonly, laboratory contamination. If a result seems inconsistent with your symptoms (for example, a positive result for a pathogen you were recently vaccinated against with no matching symptoms), your provider may repeat the test or use a different diagnostic method to confirm the finding.
