Guideline-Based Recommendations
Diagnosis
- Utilize the TriageTrue hs-TnI assay for assessing myocardial infarction.
Management
- Incorporate the assay into clinical pathways for timely diagnosis.
Monitoring & Follow-up
- Assess intra-assay and inter-analyzer precision regularly.
Risks
- Logistical constraints in obtaining suitable samples may affect results.
Patient & Prescribing Data
Patients suspected of myocardial infarction.
The assay performs adequately for intended medical use.
Clinical Best Practices
- Ensure timely analysis of whole blood EDTA samples.
- Monitor hemolysis levels to minimize interference.
