Lung Lavage Cell Profiles in Diffuse Lung Disease

Sa？etak The standard armamentarium of tests that are used by pulmonologist are laboratory tests, pulmonary function tests, different radiological techniques (conventional chest-X rays, HRCT scans, etc) and pathohistological analyses of biopsies. The minimally invasive bronchoalveolar lavage (BAL) procedure, in addition to methods earlier mentioned, is an important diagnostic instrument that can facilitate the diagnosis of various diffuse lung diseases (DLD).
