Molecular Testing and CLIA Complexity
Most molecular assays are categorized as high complexity under CLIA due to multiple manual steps, technical interpretation, and risk of contamination. This classification drives stricter personnel and validation requirements.
Key CLIA Considerations for Molecular Labs
1. Personnel Qualifications
Molecular labs must ensure that laboratory directors, technical supervisors, and testing personnel meet high complexity criteria, often including specialized molecular diagnostics experience.
2. Validation of Molecular Assays
Validation must address:
- Analytical sensitivity (limit of detection).
- Analytical specificity (cross-reactivity and interference).
- Precision and reproducibility.
- Accuracy versus a reference method or comparator.
3. Contamination Control
Policies and procedures must be in place to prevent and detect contamination, such as unidirectional workflow, physical separation of pre- and post-amplification areas, and environmental monitoring.
QC in Molecular Testing
QC for molecular assays often includes:
- Positive and negative controls in each run.
- Internal controls to detect inhibition.
- Trend analysis of Ct values or signal intensities.
