If you want to know whether a manufacturing site is GMP-compliant, don’t start with the lab—start with the batch records. These documents are the heartbeat of regulated manufacturing—and yet, they’re one of the most frequent sources of FDA Form 483 observations.
At GXP Auditing & Consulting Services, we’ve reviewed many batch records across pharma, biotech, and combination product sites. One pattern is clear:
⚠️ It’s not the complexity of the process that triggers citations—it’s the inconsistency, incompleteness, and poor oversight.
Top Batch Record Mistakes That Get You in Trouble:
Missing Signatures or Initials – A simple omission can invalidate an entire batch record.
Unexplained Deviations – If a step was skipped, altered, or repeated, but not justified… the FDA will notice.
Inconsistent Entries – Handwritten corrections, whiteouts, or overwriting create red flags for data integrity.
Failure to Link to Investigations – A discrepancy with no corresponding CAPA or deviation report? That’s a compliance failure.
Lack of Timeliness in Review – Batch reviews completed weeks later undermine real-time control and raise questions about release integrity.
How to Build a Stronger Batch Review Process:
✔️ Train Reviewers on Real-World Scenarios Not just SOPs—use case studies of actual 483s to sharpen judgment and audit-readiness.
✔️ Link QA Review to Manufacturing Events in Real Time Don’t let a paper backlog become a blind spot. Align QA timelines with production output.
✔️ Use a Checklist That’s Risk-Based, Not Generic Batch review isn’t about “checking boxes”—it’s about critical thinking and compliance assurance.
✔️ Investigate Every Discrepancy, Not Just Obvious Errors Even a small missing entry can signal larger procedural gaps.
✔️ Perform Periodic “Mock Reviews” Internal audits that simulate a regulator’s lens help your team stay sharp—and compliant.
📌 Final Thought: In today’s environment of increased regulatory scrutiny, your batch records must be bulletproof. If you’re not confident in your review process, we can help.
