Nasal swab collected using foam, rayon, flocked, or polyester swabs.
To collect a nasal swab sample, carefully insert the swab
into the nostril exhibiting the most visible drainage, or the nostril that is
most congested if drainage is not visible. Using gentle rotation, push
the swab until resistance is met at the level of the turbinates (less than one
inch into the nostril). Rotate the swab several times against the nasal
wall then slowly remove from the nostril.
