Specimen Collection 4. Explain the process to the client and obtain consent to proceed. 5. Seat the client comfortably and tilt head back (at a 70-degree angle) to straighten the passage from the front of the nose to the nasopharynx. Please Note: The swab seen in this picture does not accurately represent the swab used during NP swab collection.

Specimen Collection 9. Press the swab tip along the medial part of the septum, along the floor of the nose, until it reaches the posterior nares. Gently rotate the swab back and forth, 4 – 5 times. Allow to sit in place for a few seconds. Please Note: The swab seen in this picture does not accurately represent the swab used during NP swab collection.
