Background: Lung pathology is the leading cause of death in developed countries and is increasing at alarming rates in developing countries. Flexible fiberoptic bronchoscope revolutionized respiratory cytology as techniques such as bronchial brushing (BB), bronchoalveolar lavage (BAL), and bronchial biopsy became more easy, accessible, and popular. Fine needle aspiration cytology (FNAC) has proved to be the most helpful method for the diagnosis of lung tumors.The present study was conducted to compare Bronchoalveolar Lavage and Transbronchial Lung Biopsy in Various Lung Pathologies. Materials & Methods: This was a retrospective study among patients who were diagnosed to have various lung pathologies. After obtaining well-informed written consent, all the bronchoscopies were performed as an elective procedure. The bronchial biopsies were examined. The tissues were processed as per standard procedure. The analysis of Bronchoalveolar Lavage of all patients were taken and compared with the Transbronchial Lung Biopsy interpretation
