How does cell block work?
Like glass, CellBlockEX melts at a high temperature.
The granulates absorb heat in the process of melting, cooling the fire while forming an impervious glass layer over the fire load..
What are the advantages of cell block in cytology?
In addition to serving as an adjunct to other cytologic preparations for morphologic diagnosis, cell blocks play an increasingly important role as they yield tissue sections that can be utilized for ancillary testing such as immunohistochemical stains and molecular studies..
What is a cell block test for cancer?
The cell block technique employs the retrieval of small tissue fragments from a FNA specimen which are processed to form a paraffin block.
It is widely accepted that cell block technique increases the cellular yield and improves diagnostic accuracy..
What is cell block cytology?
Objective: The cell block (CB) technique refers to the processing of sediments, blood clots, or grossly visible tissue fragments from cytological specimens into paraffin blocks that can be cut and stained by the same methods used for histopathology..

What is the procedure of cell block in cytology?
To prepare the cell block, the specimen should be centrifuged for about 5-10 minutes at 2400-2500 rotations per minute (RCF 1125 g) and then the supernatant decanted.
About 1-6 drops of liquified HistoGel is then pipetted to the cell pellet within the conical tube..
In general, there are four steps to a cytology test including:
- Collecting the sample cells
- Processing the sample cells
- Examining the sample cells
- Sharing the results
- Cell block preparation
Cell block is a mini formalin-fixed paraffin-embedded (FFPE) biopsy obtained from fine-needle aspirate or fluid sediment.
Preservation of cytologic material in the cell block for IHC and molecular studies adds to its diagnostic accuracy[18] and enables long-term archiving for future analyses.
