Answer

Transbronchial biopsy via fiberoptic bronchoscopy has a high diagnostic yield. Results may be positive, even in the setting of normal chest radiography findings.

Standard transbronchial needle aspiration allows successful lymph node sampling in nearly all patients with sarcoidosis and is associated with high diagnostic yield regardless of disease stage. [53]
