The processing of tissues in the histology laboratory involves four steps: fixation, dehydration, clearing, and infiltration. Each of these steps requires the use of chemicals that may be hazardous, including solvents. Deciding which chemical to use is governed by a variety of considerations, including cost, type of tissue to be processed, processing method to be employed, and safety factors. The chemicals used in the histology laboratory pose a variety of safety risks; consequently, it is important to employ safe handling practices.


The goal of this chemical use in the histology lab continuing education module is to describe the chemicals used by laboratory professionals in the histology laboratory explaining the role of these substances in the processing of tissues, their safety risks, and methods to avoid harmful exposures. After studying the information presented here, you will be able to:
  • Describe the steps involved in the processing of tissues
  • Explain the advantages and disadvantages of the various solvents used in the histology laboratory
  • Discuss the hazards posed by histology solvents and how to handle them safely

When I first registered for this course, I thought it would be hard. It was clearly written and a lab tech, not working in histology, could clearly understand and comprehend the solvents used in histology.
