Handling History
Definition
Recorded events between collection and examination that may affect the specimens. These records help distinguish collection-time evidence from later changes. Refrigeration does not instantly stop development everywhere in a sample.
- Context
- Specimen history
For example, recording transfer, storage and preservation events helps a reviewer distinguish collection-time condition from later specimen changes.
A departure from a procedure needs an impact assessment rather than an automatic assumption of harmlessness or invalidity.
