Overview
In molecular laboratories, routine cleaning maintains workable clean surfaces and tools. Decontamination is the procedure-directed intensification used when contamination is suspected or confirmed.
Classification
| Practice | Trigger | Goal |
|---|---|---|
| Routine cleaning | Shift start/end; between tasks | Reduce background nucleic acid load |
| Spill response | Specimen or amplicon spill | Contain and remove contamination source |
| Event decontamination | Failed NTC / investigation | Restore area before clean restart |
| Equipment wipe-down | Schedule or after dirty use | Protect zone assignments |
Morphologic Features
Not applicable, cleaning and decontamination are process controls.
Laboratory Characteristics
- SOP defines approved agents, contact times, and sequences
- Clean restart waits until required decontamination is complete
- Waste handling must not reverse dirty materials into clean storage
Reference Intervals
Not applicable. Cleaning adequacy is procedural (SOP compliance and subsequent control performance), not a numeric patient reference interval.
Clinical and Laboratory Significance
Incomplete cleaning can seed later false positives or control failures. Cleaning after a compromised run does not convert that run's patient results into releasable valid calls.
Differential Considerations
Persistent control failures after cleaning may reflect ongoing reverse traffic, contaminated reagents, or incomplete decontamination, escalate per SOP.
Comparison Tables
Cleaning checkpoints
| Moment | Do | Don't |
|---|---|---|
| Before clean prep | Confirm cleared/cleaned bench | Prep on post-amp clutter |
| After open amplicons | Clean post-amp surfaces; PPE change | Enter clean prep immediately unchanged |
| Failed negative control | Hold; full SOP decontamination | One wipe then immediate next setup |
| End of shift | Routine zone cleaning | Skip because no visible spill |
Classification Frameworks
Not applicable . WHO disease classifications do not define molecular cleaning schedules.
Laboratory Notes
- Match intensity to routine versus event needs
- Agents and contact times are local, follow your SOP
- Cleaning supports layout and unidirectional workflow; it does not replace them
