From: Detection of SARS-CoV-2 in fecal samples with different pretreatment methods and PCR kits
Different kits showed variations in detection rate and Ct values in Trizol group. Graph depicts Ct values obtained for all clinical samples in all RT-PCR assays. a Ct values of ORF1ab and N genes detected by the 4 kits. b Data points above the horizontal dotted line are negative. The detection rate of the complete real-time RT-PCR kit is indicated below the data points, e.g. 33/84 means 33 out of 84 samples tested positive. The blue lines show the mean Ct value for each assay, triangles show the Ct values of the samples with the highest and lowest concentration. N, nucleocapsid protein of SARS-CoV-2. ORF1ab: open reading frame 1ab of SARS-CoV-2; RT-PCR: reverse transcriptase-polymerase chain reaction; SARS-CoV-2: severe acute respiratory syndrome coronavirus 2
