Indication
Additional Info Sputum can be sent in sterile universals or sputum collection pots, and must be appropriately sealed. Please indicate where high risk organisms are implicated (such as TB). Where possible, please send individual specimens for individual tests. Sputum specimens may be processed for a wide range of tests including virology, AAFB, mycology and legionella, where clinically indicated. For all sputum samples, culture is undertaken on solid media with manual plate reading.

Collection ConditionsSputum can be obtained from the lower respiratory tract by deep coughing, physiotherapy, saline induction or other clinically indicated methods. Saliva and post-nasal secretions are not appropriate. Sputum should be as fresh as possible, and if further testing such as AAFB is required, please send early morning specimens. Ideally, sputum for culture should be sent prior to commencement of antimicrobial chemotherapy, but where this is not possible, the therapeutic antimicrobial should be stated clearly. Use a sterile universal or sputum pot for collection.
