bronchial washingA cytology specimen obtained after instilling 3–5 mL of isotonic saline through a bronchoscope. The resulting fluid (usually 1–2 mL), which contains cells, microorganisms or other material from the upper airways (trachea, bronchi, bronchioles), is aspirated into a trap; the material is then centrifuged to concentrate the cells, stained, and examined by light microscopy, or cultured if infection is suspected.
