What is the Histotechnology?
What is histotechnology? Histotechnology is a science-based profession aimed to assist pathologists with the diagnosis of disease on biologic samples from patients.
What is tissue processing PDF?
A procedure which need to take place after gross examination between tissue fixation and the embedding and then sectioning of paraffin blocks is called tissue processing.14-Mar-2017
Infiltration/impregnation. The role of the infiltration agent is to remove the clearing agent from the tissue and to completely permeate the tissue with paraffin wax. This will allow the tissue to harden and produce a wax block from which thin histological sections can be cut.14-Dec-2018
Why is Histotechnology important?
The study of histology is essential for medical students in multiple ways. It helps students understand the arrangement of cells and tissues in a normal organ system. Moreover, it correlates the structure to function by correlating the differentiation of tissue structure to their specific function.19-Oct-2015
Histology and histotechnology both are used for the detection of the microscopic anatomy of plant and animal tissues. But histology studies only the tissue's anatomy. In histotechnology, we study the tissue abnormalities for disease diagnosis and the treatment of disease.
Why is xylene a clearing agent?
The reason xylene works so well for tissue processing is that it makes tissues transparent so that paraffin can fully envelop the tissue. And when preparing slides for microscopy, xylene can remove any remaining wax from slides. In this case it is used as clearing agent.29-Nov-2018
Overview of the steps in tissue processing for paraffin sections
What is the most rapid clearing agent?
Chloroform is used for routine clearing of tissues during the embedding process.Advantages:
Tissue processing is the technique by which fixed tissues are made suitable for embedding within a supportive medium such as paraffin, and consists of three sequential steps: dehydration, clearing, and infiltration.
What is the steps of tissue processing?
There are three main steps in tissue processing, namely: 'dehydration', 'clearing', and 'infiltration'. Each of the steps of the processing method involves the diffusion of a solution into tissue and dispersion of the previous solution in the series.13-Oct-2021
The technique of getting fixed tissue into paraffin is called tissue processing. The main steps in this process are dehydration and clearing. Wet fixed tissues (in aqueous solutions) cannot be directly infiltrated with paraffin. First, the water from the tissues must be removed by dehydration.
What are the stages of infiltration?
Infiltration is defined as the flow of water from aboveground into the subsurface. The topic of infiltration has received a great deal of attention because of its importance to topics as widely ranging as irrigation, contaminant transport, groundwater recharge, and ecosystem viability.
What are the types of infiltrating medium?
Various embedding substances are paraffin wax, celloidin, synthetic resins, gelatine, etc. explain various devices for tissue embedding. Paraffin wax with a higher melting point (56 to 62oC) is used for embedding.

What are the daily responsibilities of a Histotechnologist?
Common roles and responsibilities of a histology technician include: Preparing thin slices of human, animal, or plant tissue on slides for analysis by: Examining, fixing, and processing the tissue for proper sample preservation. Surrounding the tissue with paraffin wax in a process called embedding.
If you're curious and you'd like a hands-on job that impacts people's lives but isn't working directly with patients and clinicians, histotechnology can be really rewarding. There are a lot of diverse opportunities within the field.25-Jan-2018
What is histology and types?
Histology is the study of tissues and their structure. The structure of each tissue is directly related to its function, so histology is related to anatomy and physiology.
Histopathology is the diagnosis and study of diseases of the tissues, and involves examining tissues and/or cells under a microscope. Histopathologists are responsible for making tissue diagnoses and helping clinicians manage a patient's care.
What is the difference between Histotechnologist and Histotechnician?
The histotechnician is trained to process the sample for examination. The histotechnologist, who typically does the specimen examination, has advanced training and a deeper understanding of specimen collection, processing, and examination, and typically has a bachelor's degree.
