Traceability is achieved through several key practices:
Labeling: Each sample must be uniquely labeled with identifiers such as barcodes or QR codes to ensure they can be tracked throughout their lifecycle. Documentation: Detailed records must be kept at every stage of sample processing, including collection, transportation, fixation, embedding, sectioning, staining, and analysis. Electronic Systems: Many laboratories use Laboratory Information Management Systems (LIMS) to automate tracking and documentation, reducing the risk of human error. Standard Operating Procedures (SOPs): Implementing and adhering to SOPs ensures consistency in sample handling and processing.
