Laboratory Informatics
LIMS Validation
A LIMS touches nearly every regulated laboratory record: samples, specifications, results, calculations, review, release and trending. Validation effort should concentrate where an error would change a result or a disposition decision.
High-risk areas in a LIMS implementation
- Specification and limit configuration, including significant figures and rounding
- Calculations, formulas and result derivation
- Sample login, aliquoting, stability protocols and scheduling
- Instrument interfaces and automatic result import
- Out-of-specification and out-of-trend handling workflows
- Review-by-exception and electronic review/approval steps
- Access control, role design and segregation of duties
- Reporting, certificates of analysis and label generation
Data migration
Migration deserves its own plan, protocol and verification strategy. Legacy result history, specifications, methods and audit trail context often cannot be transferred with equivalent fidelity, and the accepted approach — full migration, partial migration or legacy read-only retention — should be documented and justified.
Remediating an existing LIMS
Remediation projects usually find the same pattern: heavy testing of vendor-standard functionality and thin testing of the configuration the laboratory actually depends on. Re-baselining requirements against current configuration, then risk-ranking the gaps, is normally faster than re-validating everything.
