Data integrity in peptide batch records
Practical controls for attributable, legible, contemporaneous and reviewable analytical evidence.
Data integrity starts with the ability to reconstruct what happened. A useful record identifies who performed and reviewed the work, when it occurred, which sample and instrument were involved and how the reported result was derived.
Static documents can support review, but they should not hide changes, excluded data or unexplained reprocessing. Where a decision depends on electronic records, the relevant audit trail and original-data context may also need qualified review.
For research procurement, the practical control is proportional evidence: retain enough source context to support the stated attribute, record discrepancies and prevent commercial release when material questions remain unresolved.
Practical review points
- Confirm attribution and timestamps
- Link records to sample and instrument identifiers
- Check for unexplained changes or exclusions
- Retain original-data context where relevant
- Stop release for unresolved integrity concerns
