  1. Jan 31, 2024 · Cell block (CB) is a processing method used to create a “button” in cells, which is then processed as histopathology. The CB processes routine cytology samples, such as fine-needle aspiration (FNA) and fluid samples.

  3. Mar 1, 2023 · The following review explores the most common cell block preparation methods including preparation methods with modifications with advantages and limitations of each method. Cell blocks are cytologic preparations that are processed as paraffin embedded blocks in a manner comparable to formalin-fixed paraffin-embedded tissue in surgical pathology.

  4. Collodion bag cell block procedure, hematoxylin and eosin stain, 20×. Laboratories use different approaches to cell block preparation, ranging from the low-tech “poor man’s vapor fixed” method to the high-tech Cellient automated cell block system.

  7. 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.

  8. Jan 31, 2017 · The Cell-Gel method can be simplified into 3 main steps: 1) preparing the sample; 2) constructing the cell block; and 3) processing the cell block. Sample preparation involves submitting FNA specimens directly into a hemolytic fixative or adding a hemolytic fixative to concentrated fluid samples.
