For a third-party peptide testing claim, start with the laboratory report. Check who issued it, what sample was tested, which measurements were made and how the sample links to the offered lot.
Identify who did what
Supplier, manufacturer, sampling party and testing laboratory can be different organisations. Record the role established by each document rather than assuming the seller made or tested the material. The cited supplier guidance illustrates why site and role descriptions matter; its commercial commitments are not Novum terms.Sigma-Aldrich — Quality and Supply Chain Guidelines (opens in a new tab)
An external laboratory can analyse a sample chosen by its customer. That is different from independently selecting material from a lot. To assess a wider batch claim, ask who selected the units and what the sampling plan covered.NIST sampling plans (opens in a new tab)WHO certificate model (opens in a new tab)
Read the evidence behind each claim
| Claim | Evidence to inspect |
|---|---|
| External analysis | Complete report with identified issuer and site |
| Relevant testing | Methods, results, units, limits and qualifications |
| Applicable lot | Documented product, size, sample and lot link |
| Wider batch coverage | Number and selection of independent units |
| Accredited activity | Relevant official technical schedule and report markers |
Purity, identity and content are different analytical questions. An external issuer does not make a reported purity result serve as the missing result for another attribute. Read the complete report rather than a single percentage in a supplier summary.Bachem analytical guide (opens in a new tab)
Verify the report and scope separately
Use the issuer’s own verification route to establish what it confirms about the exact document and version. That confirmation does not independently identify the physical contents of a later vial or fill a gap in the sample-to-lot record.SGS — Document-verification FAQ (opens in a new tab)WHO certificate model (opens in a new tab)
For an accreditation claim, inspect the current official schedule for the organisation, site and specific activity, plus any historical-status question relevant to the test date. UKAS explains the role of technical scope and validity checks; this guide makes no accreditation claim for Novum or a particular report.UKAS — Frequently Asked Questions: accreditation scope and validity (opens in a new tab)
A useful comparison note names the report, sample, lot, tests and remaining gap. For example: “The report identifies a tested sample and lot, but the selection of independent vials is unstated.” Keep any supplier clarification distinguishable from the laboratory’s original findings.WHO certificate model (opens in a new tab)NIST sampling plans (opens in a new tab)
