Snippet: (i) Bronchoalveolar lavage fluid should be collected using a fiber bronchoscope by clinicians or respiratory therapists. After 100-300 mL of sterilized saline being injected into the bronchia, the liquid is collected by negative pressure (∼100 mm Hg) with sterile containers. The total volume (pooled aliquots) retrieved should be >5 mL and at least 30% of the instilled volume (Fig. 5a) . 13, 14 (ii) Sputum from deep in the lung collected in the .....

After 100-300 mL of sterilized saline being injected into the bronchia, the liquid is collected by negative pressure (∼100 mm Hg) with sterile containers. The total volume (pooled aliquots) retrieved should be >5 mL and at least 30% of the instilled volume (Fig. 5a) . 13, 14 (ii) Sputum from deep in the lung collected in the morning in sterile containers is optimal for testing. Patients with a low sputum volume should be provided with aerosol inhalation using a 0.9% NaCl solution at 25 • C (Fig. 5b) . (iii) Laboratory experts should collect secretions from the palatine arch, pharynx, and tonsils with flocked swabs. Two or three swabs are required for accurate detection (Fig. 5c and d) 14 .
