BAL stands for?

BAL stands for?

• A. Bronchoscopy
• B. Blood gas analysis
• C. Bronchoalveolar lavage
• D. Bronchitis assessment

Answer: (C)

Bronchoalveolar lavage is what BAL stands for. This term names a procedure done during bronchoscopy in which sterile saline is instilled into a small part of the lung and then withdrawn to collect cells and other material from the alveolar space. The lavage fluid is analyzed for cells, pathogens, and other markers, helping diagnose infections, inflammatory or interstitial lung diseases, and certain cancers. This is different from bronchoscopy alone, which is the visual examination of the airways; it’s also not arterial blood gas analysis, which measures oxygen and acid-base status, or a nonstandard term like bronchitis assessment. BAL specifically targets the lower respiratory tract to obtain diagnostic information from the alveolar region.
