Lung lavage fluid is a term commonly used in medical contexts to describe a procedure involving rinsing the lungs with a fluid for diagnostic or therapeutic purposes. It is also known as bronchoalveolar lavage fluid. This procedure helps to obtain samples for various tests and analysis, aiding in the diagnosis of respiratory conditions. While "lung lavage fluid" is a widely understood term, its synonym "bronchoalveolar lavage fluid" is frequently employed, especially in scientific literature. Both terms describe the same technique, highlighting the importance of extracting fluid from the lungs to support accurate medical assessments and treatment decisions.
