Specimen Collection

The adequacy of a sputum specimen is determined primarily by the presence of alveolar (pulmonary) macrophages indicating that the specimen obtained is a deep cough specimen producing material from the lower airways. In addition, the specimen should not be obscured by oral or upper airway contaminants. Adequate bronchial brushing and washing specimens should contain large numbers of well-preserved bronchial lining cells with as little contaminating oral and upper airway material as possible. For bronchoalveolar lavage specimens, refer to this link: Bronchoalveolar lavage specimen collection.

Methodology: Routine cytopathologic evaluation.
Performed: Monday-Friday.
Reported: 1 day.
