Voucher Material
Definition
Documented material retained to support identification, analytical traceability and possible independent re-examination. Link it to the case, observations, analytical sampling and storage history. Keeping a voucher makes checking possible; it does not guarantee the original identification was correct.
- Context
- Reference material
For example, retaining labelled material can permit a later identification check even after another portion was sampled destructively for molecular analysis.
Destructive examination and limited material require planning.
