Nose and throat swabs for virology / molecular tests

Use a green topped virology transport medium kit (labelled as Green Top Sigma-VIROCULT swab).

Throat: Ask patient to sit upright facing a strong light, tilt head backwards, open mouth and stick out tongue. Depress tongue with a spatula. Ask patient to say ‘Ah’. Quickly but gently roll the swab over the tonsils and posterior pharynx

Nose: Ask patient to tilt head backwards. Insert swab inside the anterior nares with the tip directed upwards and gently rotate.

Place the swab(s) in the transport liquid and snap off the swab shaft at the score line so it fits into the sample pot.

Close the cap tightly and label with patient information.

Label as “nose”, “throat” or “nose and throat”
