Cellularity of Routinely Prepared Cell Blocks: Insights From an International Study.

Key Points

• The aim is to assess the variability in cellularity of cell blocks prepared by different methods and laboratories.
• Analyzed cell blocks prepared using multiple techniques across various international laboratories.
• Compared the proportion of poorly cellular cell blocks among different preparation methods.
• Significant differences observed in the cellularity of cell blocks based on preparation methods.
• Inconsistent quality of cell blocks across laboratories highlights potential processing issues.
