Correlation between the antigen level, viral load and Ct value. A Correlation between the antigen level and the viral load determined by RT-qPCR. B Correlation between the antigen level and the Ct value of RT-qPCR. C, D Correlation between the antigen level and the Ct value of Xpert. Xpert was plotted for the Ct values of N2 (C) and E (D). The decision coefficient (R2) is shown in the scatter plot
