The RT has an important role in the collection of an appropriate specimen of expectorated spu-tum. Patients should be advised to rid the mouth of contaminating saliva, either by rinsing with water or by spitting, and then to expectorate a specimen from deep within the tracheobronchial tree into a collection container. Prompt transportation to the laboratory is essential and improves the diagnostic yield from culture.
