How is a Biopsy Prepared for Histological Examination?
The preparation of a biopsy for histological examination involves several steps:
Fixation: The tissue is preserved using chemicals to prevent decay. Embedding: The tissue is embedded in a solid medium, usually paraffin, to facilitate cutting. Sectioning: Thin slices of the tissue are cut using a microtome. Staining: The tissue sections are stained to highlight different cellular components.
