Overview
Laboratory traceability is the ability to follow a reported result back to the specimen and to the reagents/lots, equipment, operator, time, and method that produced it.
Classification
| Link | Example capture |
|---|---|
| Specimen | Patient/specimen ID on order and tube |
| Reagents / lots | Kit or reagent lot numbers in use |
| Equipment | Analyzer or device identifier |
| Operator | Who performed or released the test |
| Time | Testing or release timestamp |
| Method | Method or SOP version applied |
Morphologic Features
Not applicable, this entry covers documentation and chain-of-work practice, not morphology.
Laboratory Characteristics
- Everyday habit, not audit-only paperwork
- Required for EQA, incident, and disputed-result investigations
- Local LIS/SOP define exact fields, principles are universal
Reference Intervals
Not applicable as a patient reference interval. Traceability is a completeness of record concept.
Clinical and Laboratory Significance
Without traceability, the laboratory cannot reliably investigate wrong results, suspect lots, or instrument issues, delaying protection for other patients.
Differential Considerations
Distinguish traceability (reconstruct the work chain) from documentation volume (many forms) and from accreditation clause study.
Comparison Tables
Traceability checkpoints
| Pressure point | Safe response | Unsafe shortcut |
|---|---|---|
| Reagent change mid-shift | Record new lot before testing | Assume 'everyone knows' which lot is on |
| Shared analyzer | Capture operator for the run/release | Leave operator blank |
| Disputed result | Walk the full chain | Argue from the printed number alone |
Classification Frameworks
Not applicable . WHO disease classifications do not define laboratory result traceability practice.
Laboratory Notes
- Result → specimen, lots, equipment, operator, time, method
- Missing links block investigation
- Capture while you work
