Sputum samples

Best results are achieved with freshly obtained sputa following chest physiotherapy, with an early morning sputum before the patient has eaten.

Contamination with large amounts of saliva or food leads to inadequate specimens.

Multiple specimens (usually x 3) may be necessary, but these should be sent on 3 separate days, not all taken at the same time.

Send in clean, dry container with screw cap.

If examination for eosinophils is required please indicate this on the request form.
