BAL - Bronchoalveolar Lavage

Bronchoalveolar lavage (BAL) is a medical procedure in which a bronchoscope is passed through the mouth or nose into the lungs and fluid is squirted into a small part of the lung and then recollected for examination.The cytologic examination of bronchoalveolar lavage (BAL) fluid samples can provide information that is useful in differentiating and evaluating various lower airway diseases in horses. Chronic obstructive pulmonary disease (COPD), inflammatory (small) airway disease, and exercise-induced pulmonary hemorrhage (EIPH) are examples of conditions in which diagnosis and re-evaluation can be greatly facilitated by BAL.
