WHAT YOUR REPORT SHOULD EXPLAIN
Clear identification. Clear scope. Clear results.
When comparing COA providers, ask what the certificate includes and how a recipient can retrieve the document issued by the laboratory.
Which sample?
The laboratory sample reference, material description and applicable lot information.
Which tests?
The method or test description, reported values, result units and applicable notes.
Which report?
A report identifier and issue information that distinguish the document you are reviewing.
DIRECT ACCESS

- Public lookup only for reports approved for publication
COMPARING COA PROVIDERS
Ask about the reporting process, not just the file.
Discuss report review, sample identification, correction handling and publication preferences with the laboratory. A downloadable document alone does not establish the scope of the work behind it.
- Can the provider explain the tests and result units?
- Can you identify the sample and laboratory report reference?
- How are revisions distinguished from earlier reports?
- Which details may be published, and which remain unlisted?
HELP & GUIDANCE
COA service questions
What is a certificate of analysis (COA)?
A certificate of analysis is a report that records the results of specified tests on an identified sample. Review the sample identifier, lot reference, methods, units and report date together—not just a headline result.
What should I look for when comparing COA providers?
Look for clearly identified samples, defined testing scope, interpretable results and a way to retrieve the issued document from the laboratory. Ask how corrections are identified and how public or confidential reporting is handled.
What happens when I scan a COA QR code?
An active report QR code opens the PDF associated with that specific issued COA directly. It does not require a visit to this marketing website or an intermediate verification page.
Does a COA certify a product for human use?
This website does not offer medical approval or advice. A report is limited to the submitted sample and the tests recorded on it; it should not be presented as a general endorsement or an authorization for human use.
