What third-party testing does — and does not — prove.
Third-party analytical testing adds an independent record to a supplier’s documentation packet. It is a documentation signal about a specific batch, not a certification of product safety or suitability.
What it does add
- • An independent analytical record from a named laboratory
- • Method, scope, date and signatory information
- • A reconciliation point against the supplier-uploaded certificate
- • An audit event in the batch ledger
What it does not add
- • It does not certify safety
- • It does not establish legal status in any jurisdiction
- • It does not provide medical or veterinary advice
- • It does not endorse the supplier or the product
How PurityLedger displays it
- • Lab-authenticated and third-party test linked are distinct labels
- • Lab status is shown alongside the original supplier upload
- • Hash and metadata are preserved so reviewers can reconcile records
- • Retest and dispute history remain visible
Procurement workflow
- • Compare third-party metadata against the original CoA
- • Request supporting documentation through the supplier profile
- • Escalate unresolved records for retest
- • Treat results as batch-specific, not product-wide
Important limitation: This record does not certify safety, legality, efficacy, approval, or suitability for human/veterinary use.
