Specimen Preparation

Specimen preparation encompasses all the steps allowing tissue specimens to be sectioned and stained for diagnosis purpose. The standard steps are: Grossing, Fixation, Processing, Paraffin Embedding and Sectioning using a microtome to produce very thin sections that are placed on a microscope slide ready for staining. Frozen sectioning with a cryostat is an alternative technique that is often used during surgery where the surgeon needs to locate a tumor margin to ensure it has all been removed.

Staining

The process uses a haematoxylin dye to stain cell nuclei blue and an eosin dye to stain other structures pink or red. Special stains use a variety of dyes and techniques to stain particular tissues, structures or pathogens (such as bacteria) to assist pathologists with tissue-based diagnosis. When morphology and routine staining cannot provide all the diagnostic answers, pathologists turn to advanced staining techniques: Immunohistochemistry (IHC) and in situ hybridization (ISH). IHC detects the presence of critical marker proteins in tissue samples while ISH detects target RNA or DNA sequences.
