Histological examination of lung tissue is a critical component of diagnosing lung failure. Tissue samples, often obtained through biopsy, are examined under a microscope to identify specific cellular and structural abnormalities. Common techniques include:
- Hematoxylin and Eosin (H&E) Staining: Provides general tissue architecture. - Immunohistochemistry: Identifies specific cell types and proteins. - Electron Microscopy: Offers detailed views of cellular ultrastructure.
