- Respiratory specimens: Bronchoalveolar lavage (BAL), pleural fluid, sputum. Respiratory specimen processed by NaOH NALC digestion decontamination procedure. Unprocessed specimen is preferred.
- Specimen Preparation
- Unprocessed specimens: Transport 5-10 mL respiratory specimen in a sterile container. (Min: 1 mL). Label as unprocessed.
Processed specimens: Transport 2-5 mL digested/decontaminated respiratory specimen in a sterile container. (Min: 1 mL). Identify method used for digestion and provide smear results.
Place each specimen in an individually sealed bag.
- Storage/Transport Temperature
