Batch Processing
A workflow methodology that groups samples or tasks for simultaneous processing, improving efficiency and maintaining traceability across laboratory operations.
What is Batch Processing?
- Batch Processing
- Batch processing in the laboratory context refers to grouping samples, tests, or tasks together for simultaneous or sequential processing as a unit. This approach improves operational efficiency, enables better quality control, and provides complete traceability from sample receipt through result reporting.
Types of Laboratory Batches
Sample Batches
Groups of patient or client samples processed together, often based on test type, priority, or collection time.
Reagent Batches
Lot-based tracking of reagents and consumables used in testing, linked to sample results for traceability.
Analytical Runs
Sets of samples analyzed together on an instrument, including QC samples for run validation.
Worklists
Task-oriented batches organizing work assignments for technologists or automated systems.
Benefits of Batch Processing
Operational Efficiency
Reduce setup time by processing similar samples together
Quality Control
Include QC samples in batches to validate analytical runs
Traceability
Link all samples in a batch to reagents, calibrators, and QC
Cost Optimization
Minimize reagent waste and maximize instrument utilization
Workflow Management
Better workload distribution and resource planning
Audit Support
Easy investigation of issues affecting entire batches
LIMS Batch Management Features
Automatic Batch Creation
Generate batches based on predefined rules (test type, priority, sample count)
Batch Tracking
Monitor batch status from creation through result release
QC Integration
Automatic QC sample insertion and Westgard rule evaluation
Batch Release
Review and approve/reject all results in a batch simultaneously
Reagent Linking
Associate reagent lot numbers with batches for traceability
Batch Reports
Generate worksheets, run summaries, and audit reports
Regulatory Importance
Batch processing supports regulatory requirements by maintaining complete chain of custody, enabling efficient recalls when issues are detected, and providing documentation for inspection and audit purposes. FDA 21 CFR Part 11 compliant LIMS systems maintain electronic batch records with full audit trails.
