In histology, a variety of records must be meticulously maintained. These include: - Sample identification: Unique identifiers for each specimen. - Collection details: Information on where, when, and how the specimen was collected. - Processing records: Details of fixation, embedding, sectioning, and staining procedures. - Observation notes: Microscopical findings and interpretations. - Quality control: Records of equipment calibration, reagent quality, and procedural checks. - Storage and disposal: Documentation of how and where specimens are stored and disposed of.
