What is a Certificate of Analysis (COA)?

A Certificate of Analysis (COA) is a document, produced by a testing laboratory, that reports the specific tests performed on a specific sample and the results obtained — commonly identity and purity, along with the method used for each, the date tested, and the laboratory’s identification. It is a record of what was measured, not a marketing document.

On a NuePharma lot record, the COA is the signed document itself — the underlying evidence — alongside the chromatogram it is based on, published as issued rather than redrawn or summarized.
