While you remain in the vehicle, you will be given a swab and asked to collect a sample of nasal secretions. This is done by inserting the swab into your nostril approximately 1 inch into the nasal passage (midway) with the most visible drainage or the nostril that is most congested if drainage is not present. The swab is rotated several times, removed gently and this process is repeated on the other side. Please note that you need to administer your own swab or bring someone that can do it for you.
