To sample a child, insert a cotton swab into one of their nostrils until you feel some resistance (about 2 cm). Rotate the swab against the nasal wall 5 times. Repeat the sampling process by removing the swab and inserting the same swab into the other nostril. If the child feels any pain, do not continue the test.
