title: “GMP Manufacturing Practices for POCT Lateral Flow Strip Production”
—
## Abstract
Good Manufacturing Practice (GMP) compliance ensures consistent quality of **lateral flow strips** and POCT devices. This application note from **POCT manufacturer** Due Bio details GMP requirements for **IVD Reagents OEM/ODM** production, covering facility design, personnel training, documentation, and environmental controls.
## Introduction
GMP regulations (21 CFR 210/211, EU GMP Annex 1) mandate systematic controls for medical device manufacturing. For **POCT** diagnostics, this includes clean room environments, validated processes, traceable materials, and comprehensive documentation. Implementing GMP from inception reduces regulatory risk and ensures product reliability.
## Materials Required
– ISO Class 7/8 clean room facility
– Environmental monitoring system (particle counters, pressure gauges)
– Gowning materials (bunny suits, gloves, masks, shoe covers)
– Validated manufacturing equipment (striping machines, lamination presses)
– Electronic batch record (EBR) system
– Calibration standards and reference materials
– SOP library and training records
## Step-by-Step Protocol
1. **Facility Qualification**: Design and validate clean room with appropriate air changes (≥20/hour for Class 7), positive pressure cascades, and temperature/humidity controls (20-24°C, 45-55% RH).
2. **Personnel Training**: All operators complete GMP training including hygiene practices, gowning procedures, contamination control, and documentation requirements. Annual refresher training mandatory.
3. **Material Control**: Implement quarantine/release system for all incoming materials. Use barcode tracking for full traceability from raw material lot to finished product batch.
4. **Process Validation**: Execute IQ/OQ/PQ (Installation/Operational/Performance Qualification) for all critical equipment. Document striping speed, drying parameters, and lamination settings with proven acceptable ranges.
5. **Batch Documentation**: Complete Device History Record (DHR) for each production lot including material certifications, in-process test results, equipment logs, and final QC release.
## Troubleshooting
**Q: Environmental monitoring shows elevated particle counts.**
A: Investigate HVAC system performance, gowning compliance, and material transfer procedures. Increase cleaning frequency and conduct smoke studies to identify airflow disruptions.
**Q: Batch records show inconsistent process parameters.**
A: Review equipment calibration status and operator training records. Implement automated data capture to reduce manual transcription errors.
**Q: Customer complaint traces to manufacturing deviation.**
A: Execute CAPA (Corrective and Preventive Action) investigation. Review batch records, retrain operators, and update SOPs to prevent recurrence.
## Conclusion & OEM/ODM Partnership
GMP compliance is non-negotiable for reputable **POCT manufacturer** partnerships. Due Bio, established in **1987**, maintains full GMP certification and provides complete documentation packages for **OEM/ODM** partners including audit support and regulatory inspections.
