Batch Record Review: The Complete Guide to GMP Documentation Verification
Batch record review is the final quality assurance checkpoint where QA teams systematically examine all manufacturing documentation for a specific batch to verify it was produced according to approved procedures, all process parameters were within specification, and any deviations were properly documented and resolved. This review must be completed and approved before the batch can be released for distribution.
Batch record review is the systematic quality assurance process of examining manufacturing documentation to verify that each production batch was manufactured according to approved procedures and cGMP requirements. This critical quality function serves as the final checkpoint before batch disposition and product release.
In pharmaceutical and biotech manufacturing, a single documentation error in a batch record can trigger regulatory observations, product recalls, or patient safety concerns. Quality assurance teams reviewing batch records face mounting pressure: increasing production volumes, complex multi-site manufacturing, and regulatory agencies that scrutinize documentation with greater intensity than ever before.

What Is Batch Record Review?
Batch record review is the formal quality assurance examination of all documentation associated with the manufacture of a specific batch or lot of pharmaceutical product, confirming the batch was produced according to the approved master batch record, all critical process parameters were within specification, and any deviations were properly documented and resolved.
Batch record review is the formal quality assurance examination of all documentation associated with the manufacture of a specific batch or lot of pharmaceutical product. This review confirms that the batch was produced according to the approved master batch record, all critical process parameters were within specification, and any deviations were properly documented and resolved.
The batch record review process serves multiple purposes within the pharmaceutical quality system:
Key functions of batch record review:
- Verifies compliance with current Good Manufacturing Practice (cGMP) regulations
- Confirms all manufacturing steps were completed as specified
- Documents that in-process controls and testing met acceptance criteria
- Ensures deviations and exceptions were appropriately handled
- Provides the basis for batch disposition decisions
- Creates a complete audit trail for regulatory inspections
“Regulatory Basis: Under 21 CFR 211.188 and 211.192, pharmaceutical manufacturers must maintain complete batch production and control records that are reviewed by the quality control unit before batch release.
The QA reviewer examining batch records acts as the last line of defense before a product reaches patients. This responsibility requires systematic attention to detail, thorough understanding of cGMP requirements, and the ability to identify inconsistencies that could indicate manufacturing problems.
Master Batch Record vs Executed Batch Record: Key Differences
Understanding the distinction between a master batch record and an executed batch record is fundamental to effective batch record documentation review.
What Is a Master Batch Record?
A master batch record (MBR) is the approved template that defines how a product must be manufactured. It contains all instructions, specifications, and documentation requirements for producing a specific batch size of a particular product. The master batch record serves as the controlled source document from which executed batch records are generated.
What Is an Executed Batch Record?
An executed batch record (also called a batch production record or manufacturing batch record) is the completed documentation for a specific batch. It includes all entries, signatures, data, and observations recorded during the actual manufacturing of that batch.
| Characteristic | Master Batch Record | Executed Batch Record |
|---|---|---|
| Purpose | Defines how to manufacture | Documents what was manufactured |
| Status | Approved template | Completed documentation |
| Content | Instructions and specifications | Actual data and observations |
| Quantity | One per product/batch size | One per manufactured batch |
| Changes | Require formal change control | Cannot be changed after completion |
| Signatures | Approval signatures | Execution and verification signatures |
| Storage | Document control system | Batch history files |
Master Batch Record Requirements
According to FDA regulations (21 CFR 211.186), the master batch record must include:
- Product identification - Name, strength, dosage form
- Batch size - Theoretical yield with ranges
- Complete list of components - Including quantities and grade designations
- Manufacturing instructions - Step-by-step procedures
- In-process controls - Sampling and testing requirements
- Equipment identification - Major equipment to be used
- Yield calculations - Expected yields at each stage
Establish a master batch record template review schedule to ensure all MBRs align with current regulatory guidance and your facility's latest procedures. Annual reviews catch outdated instructions before they cause confusion or errors during manufacturing execution.
GMP Batch Record Requirements: Regulatory Framework
Compliance with GMP batch record requirements is essential for pharmaceutical manufacturers operating under FDA, EMA, or other regulatory frameworks. Understanding these requirements ensures your batch record review process meets regulatory expectations.
FDA Requirements (21 CFR Part 211)
The FDA's Current Good Manufacturing Practice regulations establish specific requirements for batch production and control records:
| CFR Section | Requirement | Batch Record Impact |
|---|---|---|
| 211.186 | Master production and control records | Defines template requirements |
| 211.188 | Batch production and control records | Specifies required documentation |
| 211.192 | Production record review | Mandates QA review before release |
| 211.194 | Laboratory records | Requires complete testing documentation |
EU GMP Requirements (Annex 11 and Chapter 4)
European regulations align closely with FDA requirements but include additional specifics for computerized systems and documentation practices. EU GMP Chapter 4 specifically addresses documentation requirements, while Annex 11 covers electronic records and signatures.
Key GMP Documentation Principles
All batch record documentation must adhere to these fundamental GMP principles:
- Contemporaneous recording - Data entered at the time of activity
- Attributable - Clear identification of who performed each action
- Legible - Readable and permanent entries
- Original - First-hand documentation, not transcribed
- Accurate - Truthful representation of what occurred
- Complete - All required information included
- Consistent - Aligned with approved procedures
- Enduring - Maintained throughout retention period
“ALCOA+ Principle: The ALCOA+ framework (Attributable, Legible, Contemporaneous, Original, Accurate, plus Complete, Consistent, Enduring, Available) provides the standard for GMP documentation integrity.
