➡️ Bronchoalveolar Lavage Definition
Bronchoalveolar lavage is a technique that is used to obtain specimens from the alveolar region of the lungs for diagnostic purposes. It involves the instillation of a saline solution into the airways of the lungs through a bronchoscope. Then the liquid is suctioned back out of the lungs where it can be further analyzed for the diagnosis of certain pulmonary diseases.

➡️ Some Examples Include:
- Infections
- Pneumonia
- Pulmonary hemorrhage
- Sarcoidosis
- Hypersensitivity pneumonitis
- Lymphoma
- Tumor

➡️ Liquid Lung Sample
Once this fluid is suctioned back out, it is often referred to as a "liquid lung" sample which contains both cellular and non-cellular components. This means that the saline solution is able to collect epithelial cells and colonizing organisms from the lining of the airways of the lungs. This helps practitioners with the diagnosis of the pulmonary diseases that were mentioned.
