Histotechnology

IDevice Icon The meaning of histotechniques

Tissues from the body taken for diagnosis of disease processes must be processed in the histology laboratory to produce microscopic slides that are viewed under the microscope by pathologists.

The techniques for processing the tissues, whether biopsies, larger specimens removed at surgery, or tissues from autopsy, are described below.

The persons who do the tissue processing and make the glass microscopic slides are histotechnologists.


IDevice Icon Tssue processing
    • Once the tissue has been fixed, it must be processed into a form in which it can be made into thin microscopic sections.
    • The usual way this is done is with paraffin. Tissues embedded in paraffin, which is similar in density to tissue, can be sectioned at usually 6-8 microns.
    • The technique of getting fixed tissue into paraffin is called tissue processing.
