For biologic products, a COA typically includes:
- Lot identification and traceability: unique lot number, manufacturing site, and key dates
- Identity testing: confirmation of the intended cell type
- Purity and quality attributes: including absence of contaminants
- Viability: confirmation that cells are alive and functional at the time of release (and, where applicable, post-thaw)
- Sterility and safety testing: results for microbial contamination and other release criteria
- Release specifications: the defined criteria each lot must meet to be approved for distribution
A COA is part of a broader quality system designed to ensure consistency, traceability, and compliance with applicable regulatory standards. It allows physicians to make informed decisions with confidence, based on clearly documented product characteristics for each lot.
