Certificate of analysis
A certificate of analysis, or COA, reports analytical results for an identified sample against stated methods or specifications. Its usefulness depends on connecting the sample to the material under review.
Reading example
Keep supplier lot, laboratory sample identifier, report date, units and method together. A bulk-material report does not automatically establish the result for every filled vial.
Keep the evidence with the term
When this term appears on a report, retain the sample identifier and original wording. A glossary definition explains terminology; it cannot certify a supplied lot or replace a method-specific interpretation.
