Overview
Method verification is the documented confirmation that an established molecular method performs as expected in the laboratory's own setting before routine patient testing. Validation (introductory distinction) establishes performance for new or substantially modified methods. Exact pathways are institutional.
Classification
| Term | Introductory role |
|---|---|
| Method verification | Confirm established method locally |
| Validation (intro) | Establish new/modified method performance |
| Routine QC | Ongoing run checks after go-live |
| Lot-to-lot check | Accept new reagent lot of an in-service method |
| Calibration | Align measurement to standards/calibrators |
Morphologic Features
Not applicable, this entry covers method bring-up concepts, not morphologic identification.
Laboratory Characteristics
- Written plan and predefined acceptance criteria
- Raw data retained with authorization record
- No patient reporting before release-to-service approval
Reference Intervals
Not a single numeric reference interval. Performance characteristics and acceptance limits are method- and protocol-specific.
Clinical and Laboratory Significance
Skipping verification risks releasing molecular results from a method that has not been shown to work under local conditions, including workflow, contamination control, and instrument performance.
Differential Considerations
If go-live quality is questioned, separate missing method verification/validation from failed daily QC, overdue calibration, or incomplete lot acceptance.
Comparison Tables
Go-live language checkpoints
| Statement | Safe understanding | Unsafe shortcut |
|---|---|---|
| Kit has manufacturer claims | Still verify locally per institutional process | Start patients tomorrow without a plan |
| Call it 'validation' | Use the laboratory's defined term and pathway | Use validation as a casual synonym for QC |
| QC passing after quiet go-live | Ongoing monitoring only | Retroactive proof of verification |
Classification Frameworks
Not applicable . WHO disease classifications do not define molecular method-verification pathways.
Laboratory Notes
- Verification before patient reporting
- Validation = different pathway for new/modified methods (intro)
- QC ≠ verification ≠ validation

CLSI and Professional Guidelines
- Clinical and Laboratory Standards Institute (CLSI). Consult current CLSI molecular method documents available through your laboratory, document numbers and editions change; do not treat any single CLSI title as universal.
- Institutional molecular laboratory SOPs, assay manufacturer instructions for use (IFU), and locally adopted accreditation requirements. Always verify current local practice.
