How to Obtain a Nasopharyngeal Swab Specimen Insert the swab into the nostril, parallel to the palate. If you detect resistance to the passage of the swab, back off and try reinserting it at a different angle, closer to the floor of the nasal canal. The swab should reach a depth equal to the distance from the nostrils to the outer opening of the ear. The CDC recommends leaving the swab in place for several seconds to absorb secretions and then slowly removing the swab while rotating it. Your institution may also recommend rotating the swab in place several times before removing it.
