Insert the entire collection tip of the swab provided (usually 1/2 to 3/4 of an inch, or 1 to 1.5 cm) inside the nostril. Firmly sample the nasal wall by rotating the swab in a circular path against the nasal wall at least 4 times. Take approximately 15 seconds to collect the specimen. Be sure to collect any nasal drainage that may be present on the swab.
Repeat in the other nostril using the same swab.
