Histological Tissue Examination

Histological tissue examination provides microscopic morphology assessment detecting pathological changes. Fixed tissue staining with H&E dyes visualises cellular architecture. Immunohistochemistry employs antibodies detecting specific antigens. Electron microscopy reveals subcellular structures. Quantitative image analysis measures tissue changes objectively.

Pathologist interpretation requires expertise and standardisation. Digital pathology enables remote consultation. Regulatory submissions employ histological findings supporting safety conclusions. Quality control assessments detect unexpected tissue changes. Post-approval monitoring tracks tissue-level treatment effects.
