Bronchoalveolar lavage is similar to a transtracheal aspirate in that a small volume of sterile fluid is instilled into the airways and then re-aspirated in hopes of retrieving material from airway secretions and lesions. The difference is that with bronchoalveolar lavage, the lower parts of the airways are sampled. Bronchoalveolar lavage (BAL) is particularly helpful in patients in whom the cause of pulmonary disease or infection is not known. Depending upon the nature of the material obtained by bronchoalveolar lavage, we may need to culture some of the material in order to definitively determine whether or not there are bacteria or fungi present.
