Insert the entire soft tip of the swab into a nostril (usually 1/2 to 3/4 of an inch). You do not need to go deeper.
Using medium pressure, rub the swab against all of the inside walls of your nostril.
Make at least 5 BIG CIRCLES. DO NOT just spin the swab.
Each nostril must be swabbed for about 15 seconds.
Note: False negative result may occur if the nasal swab is not properly collected.
