Processing Fatty Specimens

PACE credits are no longer available for webinars more than 6 months old.


One of the most critical steps in histology is fixation, especially when it comes to fatty tissue. If a specimen is not well fixed, the lack of full fixation could affect staining steps and possible diagnosis. A laboratory thoughts of what alcohols to use in dehydration steps and the solutions used in clearing steps in optimum processing of fatty tissue is an important step to get these tissues to ultimate processing and fixation. This presentation will review the process of processing fatty tissue, processors types, and good quality measures for ultimate fixation of fatty tissues.

Learning Objectives:

  1. Review the process of specimen handling before processor.
  2. Review Fatty Specimens and why they are so difficult to process.
  3. Overview of the different technologies for processing and solutions used.
  4. Expand on good quality techniques for processing fatty specimens.
