Special instructions for collection
A sputum or BAL sample for the respiratory pathogen PCR panel (which includes Legionella) is the preferred sample for diagnosis as it includes several differential diagnoses. However, sputum or BAL may not always be available, and therefore urinary antigen testing may be appropriate. Do not send in boric acid containers; they cannot be processed. Specimens will only be tested for Legionella urinary antigen if the patient meets at least one of the following criteria:
• Intensive Care patient
• Immuno-compromised/suppressed patient
• CURB65 score ≥3
• Recent foreign travel
• Spa exposure
