Start with the report identity

A third-party report should identify the laboratory document itself before you interpret any result. Record the report number, issue date and sample identifier, then compare them with the information supplied by the vendor.

The report applies to the sample named in the document. It should not be treated as evidence for every lot, specification or future production run.

  • Report number and issue date
  • Sample name or identifier
  • Submitted specification
  • Laboratory verification link

Check what was actually tested

Purity, content and endotoxin are different measurements. A document covering one measurement does not automatically establish the others. Read the test name, method and reported units before comparing results.

If the document scope is unclear, request the complete report number and ask the supplier which physical sample was submitted.

Verify the original document

Use the issuing laboratory's verification method when one is provided. A screenshot or reformatted summary is less useful than the original report because important identifiers and verification details may be omitted.

Our report library is searchable by complete report number. Customers who need the relevant number for an available product can request it from the sales team.
