From: Urgent care study of the LumiraDx SARS-CoV-2 Ag Test for rapid diagnosis of COVID-19
CTs were available for 56.8% of negative LumiraDx SARS-CoV-2 Ag Tests with positive PCR results. The average CT between different SARS-CoV-2 gene and nucleic acid sequence targets is reported for each patient specimen represented. CTs were not available for SARS-CoV-2 testing performed using the Hologic method. CT, cycle threshold; (green circles) LDT, a laboratory-developed PCR testing method; PCR, polymerase chain reaction; (red circles) Roche PCR-based testing method; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2
