CPT Codes

Collect samples so as to avoid as much upper respiratory tract flora as possible.
Specimens include: sputum, BAL, bronchial washings & brush, pleural fluid, chest drainage, trans-tracheal aspirate, lung tissue

Lung tissue:
Submit tissue in sterile container inside a ziplock bag.
Submit as much tissue as possible.

Washings and Aspirates:
Submit in sterile container inside a ziplock bag.

1. The specimen must be collected under the supervision of a nurse or physician to ensure that proper collection procedures are followed.
2. Have the patient rinse their mouth with some fresh drinking water and swallow the water.
3. Instruct the patient to cough deeply to bring up sputum from the lungs. (Be sure to tell the patient you do not want post nasal discharge).
4. Expectorate the sputum into a sterile, leak-proof container. (The amount of the sputum is not as critical as its quality. If the patient cannot produce sputum, try again later. Do not insist on a specimen. That will usually only produce a sample of saliva or post nasal discharge.)
5. Patients older than 5 years who cannot follow these instructions should have specimens collected by suction (respiratory therapist). Do not substitute a throat swab.
