Don’t Submit Certificates of Analysis Without QA Verification

Don’t Release Certificates of Analysis Without QA Review and Approval

Remember: Always route CoAs through QA for verification — skipping this step may result in incorrect batch release and GMP violations.

Why This Matters in GMP

The Certificate of Analysis (CoA) is an official document that confirms whether a batch of product, raw material, or excipient meets predefined specifications. It plays a critical role in batch release decisions, regulatory submissions, and product transfers. If a CoA is generated and shared without QA verification, there is a high risk of clerical errors, data misrepresentation, or omission of key compliance elements like signatures, traceability, or approval stamps.

For example, a CoA submitted without verifying impurity limits or residual solvents could lead to the shipment of substandard product. If caught during customer or regulatory inspection, such an error reflects a breakdown in the company’s quality system and damages credibility.

Regulatory and Compliance Implications

21 CFR Part 211.165 requires that all finished product testing results be reviewed and approved by the quality unit. EU GMP Chapter 4 mandates that documentation used to certify products must be reviewed, authorized, and retained appropriately. WHO GMP emphasizes quality oversight in the generation and verification

of all release documentation, including CoAs.

Auditors examine CoA issuance procedures, signature logs, batch disposition workflows, and alignment between raw data and reported results. Any CoA issued without documented QA review may be cited as a significant lapse in quality oversight and documentation control.

Implementation Best Practices

Design SOPs that mandate QA review and sign-off for all CoAs. Use controlled templates with version control, mandatory fields, and e-signature authentication. Ensure CoAs reflect actual batch numbers, method versions, and final test results from the approved analytical reports.

Train QC analysts and QA reviewers on CoA generation, approval responsibilities, and error detection. Link CoA issuance to batch release systems so that release cannot proceed without final QA clearance.
