|CONTAINER TYPE:||Sealed sterile container; Leuken`s tube|
|COLLECTION:||Specimens are to be collected from a site prepared utilizing aseptic technique. Non-bacteriostatic sterile saline should be used when obtaining washings and/or lavage specimens. Material obtained by needle aspiration (transbronchial lung biopsy) is injected into a sealed sterile container.|
|REJECTION CRITERIA:||Inappropriate specimen container, insufficient specimen volume.|
|MINIMUM VOLUME:||2 mL|
|HANDLING INSTRUCTIONS:||Specimen should be transported as soon as possible. When transportation is delayed, refrigerate.|
No Legionella species isolated
|LIMITATIONS OF TEST:|
The sensitivity of the culture is 50-80%; however, the specificity is 100%.
Culture: conventional culture using routine media and media selective for Legionella isolation.
