Box plot diagrams representing the Ct values obtained for N = 100 samples previously tested SARS-CoV-2 positive with Meril Covid-19 detection kit. Dark bar: median; box: 25–75% interquartile; whiskers and dots: range in the box plot. Significant difference in Ct values was observed upon testing with In house SARS-CoV-2 detection assay (Target 1, Target 2 and Target 3) when compared with that of Meril Covid-19 detection kit (Orf1b and N gene). Enhanced sensitivity of the in-house RT-PCR assay is evident from the plot showing comparable reduction in median Ct value.
