After the removal of a tissue sample from the body of a patient, a series of physical and chemical processes must take place to ensure that the final microscopic slides produced are of a diagnostic quality.
The quality of the structural preservation of tissue component is determined by the choice of exposure times to the reagents during processing. Every step in tissue processing is important, from selection of the sample, determining the appropriate protocols and reagents to use, to staining and final diagnosis.
Producing quality slides for diagnosis requires skills that are developed through continued practice and experience. As new technology and instrumentation develop, the role of the histology laboratory is patient care will continue to evolve, providing standardization of process, increased productivity, and better utilization of the resources available.
Tissue Processing procedure involving fixation, dehydration, clearing and even infiltration was performed in manual way in past. But by the emergence of the new technologies the Tissue processing Device is presented to the histopathology laboratories to minimize the human mistakes, accelerating the process and preparing quality tissues.
