- A PCR cycle threshold (CT) value indicates viral load: low CT means high viral load detected quickly; high CT means low viral load requiring many amplification cycles. — Rapid Antigen Testing as a COVID-19 Public Health Surveillance Tool
- CT values are currently not legally reportable to patients in any standardized way. — Rapid Antigen Testing as a COVID-19 Public Health Surveillance Tool
- In Massachusetts, the average CT value across newly diagnosed COVID-positive patients was approximately 36–37, suggesting most had already passed their peak infectious period. — Rapid Antigen Testing as a COVID-19 Public Health Surveillance Tool
- Reporting CT values to contact tracers would allow them to prioritize actively rising-load cases and deprioritize stale cases where the infectious window has already passed. — Rapid Antigen Testing as a COVID-19 Public Health Surveillance Tool
