Overview
Urgent or significant molecular communication is policy-defined notification of designated molecular results to authorized clinical contacts, using validated wording and documented notification details.
Classification
| Notification step | Requirement |
|---|---|
| Readiness | Specimen, controls, criteria, final category ready |
| Recipient | Authorized contact per institutional list |
| Content | Validated result language only |
| Limits | SOP limitation/inconclusive wording when applicable |
| Documentation | Who / when / what / read-back if required |
Morphologic Features
Not applicable, this entry covers molecular notification workflow, not morphologic identification.
Laboratory Characteristics
- Verbal message must match the written report
- Significant-result lists are institutional
- Do not notify incomplete or invalid interpretations as clinical answers
Reference Intervals
Quantitative urgent results still require correct units and reportable-range framing. Ct/Cq values remain method-dependent and are not universal severity scores.
Clinical and Laboratory Significance
Timely accurate notification supports infection control and clinical pathways. Overstated certainty during a call can be as harmful as delayed communication.
Differential Considerations
Before calling, exclude unfinished control review, invalid runs, wrong patient identity, and pressure to expand into treatment advice.
Comparison Tables
Urgent communication checkpoints
| Communication | Safe | Unsafe |
|---|---|---|
| Detected on notifiable assay | State validated detected language + document | 'Active disease, start drugs now' |
| Failed controls | 'Invalid / unable to report' + next SOP step | 'Negative for now' |
| Quantitative value | Number + units + range framing | Bare Ct as severity label |
Classification Frameworks
Not applicable . World Health Organization (WHO) disease classifications do not define institutional molecular notification lists.
Laboratory Notes
- Ready → authorized contact → validated wording → document
- Positive ≠ active disease; negative ≠ exclude; invalid ≠ negative
- No unsupported certainty on the phone or in the LIS

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.
