Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.

Bronchoalveolar lavage (BAL) is a procedure that is sometimes done during a bronchoscopy. It's done to collect a sample from your lungs. It is also called bronchoalveolar washing. During the procedure, a saline solution is put through the bronchoscope to wash your airways and capture a …

Bronchoalveolar lavage (BAL), performed during flexible bronchoscopy, has gained widespread acceptance as a minimally invasive method that provides important information about immunologic, inflammatory, and infectious processes taking place at the alveolar level [1].

Apr 15, 2021 · The primary objective of the study is to describe the cellular characteristics of bronchoalveolar lavage fluid (BALF) of COVID-19 patients requiring invasive mechanical ventilation; the secondary outcome is to describe BALF findings between survivors vs …

Bronchoalveolar lavage (BAL) explores large areas of the alveolar compartment providing cells as well as non-cellular constituents from the lower respiratory tract. It opens a window to the lung. Alterations in BAL fluid and cells reflect pathological changes in the lung parenchyma. The BAL procedure was developed as a research tool.

Jan 11, 2025 · Bronchoalveolar lavage (BAL) is a diagnostic tool in respiratory medicine, providing insights into the cellular and molecular environment of the lower respiratory tract.

Nov 24, 2020 · Bronchoalveolar lavage (BAL) is a technique used to collect the contents of the airways. The fluid recovered, called BAL fluid (BALF), serves as a dynamic tool to identify various disease pathologies ranging from asthma to infectious diseases to cancer in the lungs.

Dec 29, 2023 · Liquid biopsy is a method for detecting circulating biomarkers in the blood and other body fluids containing genetic information from primary tumor tissues. Bronchoalveolar lavage fluid (BALF) is a potential liquid biopsy medium that is rich in a variety of bioactive substances and cell components.

Bronchoalveolar lavage (BAL) is a technique that allows the recovery of both cellular and noncellular components from the epithelial surface of the lower respiratory tract and differs from bronchial washings, which refer to the aspiration of either secretions or small amounts of instilled saline from large airways /1/.

May 4, 2017 · Bronchoalveolar Lavage (BAL) is an experimental procedure that is used to examine the cellular and acellular content of the lung lumen ex vivo to gain insight into an ongoing disease state. Here, a simple and efficient method is described to perform BAL on murine lungs without the need of special tools or equipment.
