A COA is tied to a single lot, identified by its lot number, rather than to a product line generally. Confirm with the supplier what the COA for a given product lists; it may include tests performed, such as sterility testing, and other release criteria depending on the supplier's internal specifications. Because requirements and formats vary by product type and by supplier, a COA for one product line is not a template for reading another.
Requesting a COA before an order ships, and matching the lot number on the COA to the lot number on the product received, is a basic way for a clinic to confirm that the documentation it reviewed corresponds to the product it actually has in inventory. A COA that cannot be matched to a physical lot number is of limited use for recordkeeping.
A COA is a records document, not a marketing claim. It describes what was tested and found for that lot; it does not describe what the product does clinically, and a buyer should not read test results, such as a particle count or protein panel, as a statement about intended use or outcome.
A matched, lot-specific COA is the basic documentation a clinic needs to support its own quality and recordkeeping obligations for any tissue or biologic product it stocks.
