People often employ RT-PCR and Ct value. Even non-technical people can comprehend the relationship between Ct and COVID-19. Ct value is an RT-PCR result that indicates the sample's infection or viral load. RT-PCR detects COVID-19 (SARS-CoV-2) and quantifies infectivity. Higher viral load samples start amplifying earlier, hence Ct 16 shows very high infection compared to Ct 30.
