What a record
can support

Identity, purity, measured content, and contaminant screening answer different questions. A published record supports only the fields and sample it reports.

Find a lab report
Identity
Identity evidence addresses what the tested sample is. It does not establish an unreported purity, quantity, sterility, or origin result.
Purity
A purity value belongs to the reported sample and method. It is not a blanket claim for another lot, configuration, or product.
Measured content
Content or quantity results remain separate from purity. One value cannot be substituted for the other.
Additional panels
A contaminant, sterility, or other panel is represented only when the source document expressly includes it.

How a document
reaches the site

We first match the report to its product, configuration, lot or supplier record. We then review the stated sample, method, laboratory, dates, results, and limitations. Public release requires an approved source file and a confirmed record match.
