The CAP and the National Society for Histotechnology (NSH) have released an evidence-based guideline, "Uniform Labeling of Blocks and Slides in Surgical Pathology."
The panel addressed the over-arching question, "What are the essential elements for the proper labeling of paraffin blocks and microscopic slides in the routine practice of surgical pathology?" and developed 12 recommendations, including these key points:
- Laboratories should ensure that all blocks and slides are clearly labeled using two patient identifiers.
- Laboratories should ensure that the accession designation used on the surgical pathology report and all blocks and slides from that accession, includes the case type, year, and a unique accession number.
Accurate labeling of paraffin blocks and microscopic glass slides in the practice of surgical pathology is essential to ensure patient safety and to reduce the potential risk of misdiagnosis due to improper specimen identification. The Uniform Labeling of Blocks and Slides in Surgical Pathology guideline provides a consistent method for labeling these specimens.
