Topic starter   [#30804]

A reagent dossier contains a summary purity percentage but not the method or underlying trace. The draft index calls it fully verified. Which parts of that label can actually be supported?

Discussion record: RESEARCH-30793.

Separate document provenance, identity, purity and the conditions measured. A percentage without its method and sample linkage cannot establish all of those claims.

Ask whether the sample identifier, issuing laboratory, report date and relevant analytical method can be verified. A copied certificate may be genuine as a document while its relationship to the sample remains unestablished.

A chromatographic peak-area figure and net material content answer different questions. Record the report’s own definition and units before comparing it with another percentage.

The index should list supplied evidence and missing evidence separately. Use method-specific wording rather than a blanket verified or safe label.

Even an authentic analytical report has scope limits. It is not by itself a demonstration of clinical efficacy, sterility or suitability for human use.

Proposed correction: documentation supplied; method and sample linkage incomplete. Add a dated update if verifiable primary material later resolves those gaps.
