Lung biopsy may be considered when diagnostic uncertainty exists. Fiberoptic bronchoscopy, with bronchoaveolar lavage and transbronchial biopsies, are useful in the evaluation of exposure-related granulomatous lung disease such as hypersensitivity pneumonitis. Surgical lung biopsy may be required to confirm a diagnosis of bronchiolitis or diffuse interstitial lung disease.

Video-assisted thoracoscopy (VATS) is rarely used for larger lung tissue sampling.
