Correlation of SARS-CoV-2 Subgenomic RNA with Antigen Detection in Nasal Midturbinate Swab Specimens
Figure 1

Figure 1. Correlation of sgRNA levels with total SARS-CoV-2 RNA in samples from study participants in Atlanta, Georgia, USA. A) N2 Ct values for samples in which sgRNA was detectable (gray dots) or not detectable (red dots). Horizontal bars indicate means, and error bars indicate SDs. B) sgRNA Ct values versus corresponding Ct values for the N2 target. Results of simple linear regression (black line) and error bars (dotted lines) are shown. Line of identity (gray line) is shown for reference. Ct, cycle threshold; N2, nucleocapsid 2; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; sgRNA, subgenomic RNA.
