What components constitute a histological surveillance system?

A comprehensive histological surveillance system typically includes several components:

1. Standard Operating Procedures (SOPs): Detailed protocols for tissue processing, staining, and examination.
2. Quality Control (QC): Regular checks and calibration of equipment, and validation of staining techniques.
3. Quality Assurance (QA): Systematic review of histological results to ensure consistency and accuracy.
4. Data Management Systems: Electronic databases to store, retrieve, and analyze histological data.
5. Training Programs: Continuous education and training for histotechnologists and pathologists to keep them updated on best practices.
