COA Checklist and Red-Flag Checker

Score a certificate of analysis against lot specificity, test methods, freshness, and injectable-relevant verification signals.

Why this tool exists

Built to make a COA easier to interrogate without pretending that a PDF alone proves product quality.

Move through critical proof points first, then supporting signals.

Critical gaps

Missing critical items should slow the review down immediately.

Use case filter

injectable

Injectable mode keeps the sterility and endotoxin checks visible.

Document basics

Check lot specificity, freshness, and whether the document can be authenticated.

Identity and purity

Make sure the packet proves what the material is, not just that something measured high.

Injectable safety

Only visible when the use case could involve injection.

Packet quality

Weak packet

A better packet reduces ambiguity; it does not guarantee product quality.

Critical gaps

4

Missing critical items should slow you down immediately.

Start with the hard-to-fake items

Begin with lot match, independent lab details, and an explicit identity method. Those checks usually separate a real packet from a decorative PDF fastest.

Critical items are still missing

  • Batch or lot number clearly matches the vial in hand
  • Report names an independent third-party lab
  • Identity method is present (for example MS or LC-MS)
  • Sterility testing is present for injectable use

Follow-up questions to ask next

  • Ask for the lot-specific report or packet that actually matches the product in hand.
  • Confirm which lab performed the test and whether the lab can verify the document.
  • Ask when this exact lot was tested and whether the report predates the batch by too much.
  • Ask for the stated purity percentage instead of a generic 'passes' claim.

Best used for

  • Reviewing whether a COA looks lot-specific or generic
  • Checking for identity confirmation beyond purity alone
  • Flagging missing sterility or endotoxin signals for injectable use

Outputs

  • Checklist score
  • Critical missing items
  • Suggested follow-up questions before trusting the report
