Batch record review is the systematic evaluation of manufacturing and packaging documentation to verify that every batch of pharmaceutical product was produced and tested in compliance with approved specifications and GMP requirements. It is the final quality checkpoint before a batch is released for distribution.
What Is Batch Record Review?
Each batch has a Master Batch Record (MBR) defining the manufacturing instructions and a Batch Manufacturing Record (BMR) documenting what actually occurred. Reviewers confirm that all steps were executed as specified, all in-process and finished product tests meet specifications, all equipment was within calibration, and all deviations have been properly investigated. The review ends with a disposition decision: release, rejection, or quarantine.
Regulatory Framework
21 CFR Part 211.188 and 211.192 require that each batch record be reviewed and approved by the Quality Unit before release. EU GMP Chapter 4 (Documentation) and Chapter 1 (Quality Management) specify documentation and review requirements. ICH Q7 Section 2.3 requires batch record review for APIs. WHO GMP Annex 2 includes equivalent requirements.
Key Requirements
The reviewer must check for: all required entries completed and signed by the operator; all critical process parameters within specified ranges; all hold times and in-process controls satisfied; all equipment and room use logs completed; all raw materials and components reconciled; and all deviations or atypical events documented and linked to investigations (see Deviation Management). A Quality Control (QC) review of analytical results is required before the final Quality Assurance (QA) disposition.
Practical Implementation
Many manufacturers use electronic batch record systems that enforce data completion and prevent release until all fields are verified. Paper-based systems require systematic line-by-line checking with a review checklist. Discrepancies found during review are documented and investigated; the batch cannot be released until all investigations are closed.
Common Pitfalls
Missing signatures or incomplete data entries are the most common review findings. A more serious issue is failing to identify trends — for example, repeated minor deviations that individually do not block release but collectively indicate a process control problem requiring formal investigation.
Conclusion
Thorough batch record review is the last line of defense against releasing non-conforming product. A disciplined review process, supported by clear procedures and trained reviewers, ensures that only compliant, safe product reaches patients.
