Match identifiers first

Confirm the product name, amount or format, batch or lot number, sample identifier, document identifier, and supplier reference. Stop when a key identifier does not match the received container.

Review analytical context

Check the issuing laboratory, test and report dates, methods, units, acceptance criteria, results, authorization, page count, and revision status. Note whether the document distinguishes specifications from measured results.

Record the review

Link the verified certificate to the internal receiving or inventory record. Record who reviewed it, when the review occurred, and how any discrepancy was resolved.

References and further reading

Open the original sources and evaluate their methods, limitations, and applicability independently.
