COVID-19 Testing Technologies
COVID-19 diagnostic testing has evolved significantly since the pandemic began. Healthcare facilities must understand the differences between testing methodologies to select appropriate kits for their clinical needs, testing volume, and turnaround time requirements.
Test Type Comparison
| Feature | RT-PCR | Rapid Antigen | Rapid Molecular |
|---|---|---|---|
| Sensitivity | 95-99% | 80-95% | 93-97% |
| Specificity | >99% | >97% | >99% |
| Time to Result | 1-4 hours | 15-30 minutes | 15-45 minutes |
| Equipment Needed | Lab instruments | None (POC) | Analyzer unit |
Procurement Considerations
Evaluate tests based on FDA Emergency Use Authorization (EUA) status, sensitivity and specificity data from independent validation studies, supply chain reliability, and total cost per test including labor and equipment.
Medical Disclaimer
Testing recommendations and regulatory authorizations are subject to change. Always refer to current CDC, FDA, and WHO guidelines for testing protocols.
