CT value overview for 3600 clinical specimens tested with the RKI/ZBS1 SARS-CoV-2 protocol. CT values for the four PCR assays included in the RKI/ZBS1 SARS-CoV-2 protocol as determined for the first 3600 specimens. Red symbols show the SARS-CoV-2 assays (negatives not shown), blue squares the inhibition control KoMa and green circles the nucleic acid detection by c-myc amplification. The constant detection of the inhibition control KoMa can be seen, and the scattering of the nucleic acid content demonstrated by c-myc as well as the similar CT values for the E-Gene and the orf1ab assay
