Comparison of extraction methods using 10 clinical nasopharyngeal swab specimens. A single sample that was not detected is shown at 30 CT (the internal processing control [PRC] from the Lyra kit was detected in this sample). Statistical analyses performed in GraphPad Prism v8.0. Note that the Lyra assay removes the first 10 CT cycles (add +10 CT values to compare with conventional methods).
