Fig 1 — Comparison of C_T values for both testing platforms and distribution of EM/RGQ Lyra SARS-CoV-2 test C_T values from March-April, 2020. (A) Scatter dots depict each positive C_T value as a point. Red line depicts the median C_T value. We find differences in C_T values obtained between platform (unpaired parametric t-test p value .0012). (B) Histogram depicting number of samples binned to their lowest whole number for EM/RGQ samples. Distribution of C_T values indicates our data is not normally distributed as the Shapiro-Wilk test (p value <.0001) did not pass normality.
