Specimen collection procedure

Preparatory instructions before the test *

Nasopharyngeal Swab

A dry swab would be inserted through one nostril straight back (not upwards), along the floor of the nasal passage until it reaches the wall of the nasopharynx. The distance from the nose to the ear would give an estimate of the distance the swab should be inserted.

The swab is gently rotated and left in its place for up to 10 seconds.

The swab is placed immediately into the transport container.

The swab must be collected within 3 days of symptoms.

There may be a feeling of choking or other discomfort.

One must sit with their head against a wall to reduce the tendency of pulling away during the procedure.

*Subjects suffering from any illness or on oral or injectable medications are advised to consult their physician prior to requesting any tests or procedures.
