Overview
A Certificate of Analysis reports analytical information for a specific material or lot under defined test conditions.
Purpose
The purpose is to explain COA terminology and its role in research documentation.
Scientific Background
COAs commonly report identity, purity, lot number, method information, testing date, and laboratory-issued results.
Laboratory Considerations
- Review identity and purity as separate analytical questions.
- Connect COA data to the correct lot.
- Recognize that COAs report analytical findings, not clinical suitability.
Quality Considerations
COA quality depends on the test method, issuing laboratory, traceability, and completeness of reported information.
Documentation Standards
COA records should be retained with lot records and research documentation where applicable.
Common Misconceptions
- Purity alone does not confirm identity.
- A COA is not a medical clearance document.
- A COA should not be generalized to unrelated lots.
