How to Collect a Nasopharyngeal Swab Specimen for Pertussis Testing

Effective specimen collection is paramount for obtaining reliable test results. Nasopharyngeal (NP) swabs are the preferred specimen for pertussis testing, as B. pertussis colonizes the nasopharynx. Proper technique is crucial to ensure the collection of an adequate sample. Here’s a step-by-step guide to NP swab collection:

1. Prepare the patient by explaining the procedure and ensuring cooperation.

2. Position the patient comfortably, tilting their head slightly backward.

3. Gently insert a flexible NP swab into one nostril until resistance is met (approximately 1-2 inches).

4. Rotate the swab against the nasopharyngeal wall for 5-10 seconds to collect epithelial cells and secretions.

5. Withdraw the swab carefully and place it into a sterile viral transport medium.

6. Repeat the process with the same swab in the other nostril, if necessary, using a new swab if contamination is suspected.

7. Label the specimen with patient information and other required details.
