The cell block is prepared from the pellet of centrifuged cell suspension by adding plasma and thrombin to enmesh the cellular material in a clot (Fig. 1).
Add up to 20 mL of specimen to a falcon tube and centrifuge for 10 minutes at 1,650 rpm.
After centrifugation, the supernatant is decanted.Aug 17, 2017.
Proteins are the building blocks of cells..
What is cytology? Cytology is the exam of a single cell type, as often found in fluid specimens.
It's mainly used to diagnose or screen for cancer.
It's also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas..
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..
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..

Many other cell block methods and preparation techniques exist including:
Pericardial Fluid Cytology:
CellBlockistry, the science and art of art of cell-block making, refines cell-blocking of variety of cytology specimens. [ 79] However, currently, multiple methods have been practiced with significant variation with lack of reproducibility in qualitative and quantitative parameters of final cell-blocks.
