What are the Common Histological Techniques Used in Diagnosis?
Several techniques are employed in histology to prepare and examine tissue samples. These include:
Biopsy: Obtaining a tissue sample from a living patient for diagnostic purposes. Staining: Using various dyes to highlight different components of the tissue, such as Hematoxylin and Eosin (H&E) staining. Fixation: Preserving tissues with chemicals like formalin to prevent decay and maintain structure. Sectioning: Cutting tissues into thin slices (sections) using a microtome for microscopic examination. Immunohistochemistry (IHC): Utilizing antibodies to detect specific antigens in tissues.
