How to Read a Certificate of Analysis
Summary
What a Certificate of Analysis typically contains, which fields matter, and the questions worth asking when reviewing one.
Key concepts
- Lot identification
- Test method
- Specification vs. result
- Issuing laboratory
Research context
A COA is a document that reports analytical results for a specific lot. Its value depends on who performed the testing, which methods were used, and whether it corresponds to the material in hand.
Evidence type
Other. Evidence labels are navigational aids. Preclinical findings do not establish human safety or efficacy.
Limitations
Formats vary between laboratories. A COA describes the tested sample, not every unit of a lot under all storage conditions.
