These techniques have variable sensitivities and specificities, although there are accepted criteria for semiquantitative cultures to improve the diagnostic reliability of bronchoscopically derived cultures.

Protected brush/cultures from bronchoalveolar lavage (BAL) reflect airway colonization (eg, Aspergillus, MSSA/MRSA, P aeruginosa) rather than nosocomial pneumonia/ventilator-associated pneumonia (VAP) pathogens in the lung parenchyma.
