VendorInvestigate — what its reports establish

VendorInvestigate: Documentation and supplier-practice review. What a report from this service does and does not establish, and how we cite it.

Scope

VendorInvestigate — Documentation and supplier-practice review.

This page describes how this community reads and cites reports from this service. It is not an assessment of the service and we have no relationship with any of the four we cite.

What a report contains

VendorInvestigate reviews documentation and supplier practice rather than testing vials. Its findings on our vendor pages therefore look different from the others: internal consistency of certificates, traceability of lot identifiers, whether a method is identified specifically enough to reproduce, and whether a specification has been reported in place of a measurement.

This is the only one of the four services that can tell you something about a supplier's systems. It is also the one that cannot tell you anything about what is in a container, and our vendor pages say so explicitly where a review is the only record available.

An "insufficient to verify" finding from a documentation review is not a negative finding about a product. It means the documents did not contain enough to check. We use exactly that wording for that reason.

How we cite it

On a vendor documentation page, an entry citing this service records: the compound, the lot identifier, the date, the method as reported, the result, and the state — verified, unverified or disputed. An entry missing any of those is incomplete and gets moved to the discussion rather than the record.

"Unverified" means the available material did not contain enough to check. It is not a negative finding about a product, and we use that wording deliberately.

Limits

One service, one laboratory, one vial, one date. Agreement between two independent services on the same lot is a much stronger statement than a single high number, and our records mix services for exactly that reason.

None of these services can tell you whether something is safe to use. That is a different question and it is not an analytical one.
