Repeatability analysis for the FMDV SAT1, SAT2 and SAT3 assays. FMDV genomic RNA was extracted on three separate days from prototypic FMDV cell culture isolates SAT1/KEN/4/1998, SAT1/BOT/12/2006, SAT2/SAU/1/2000, SAT2/EGY/2/2012, SAT3/SAR/1/2006 and SAT3/ZAM/1/2017 as well as a PBS extraction control (Extn Con). Extracted RNA from each replicate was also analyzed using the SAT1 (A), SAT2 (B), and SAT3 (C) srRT-PCR assays on three separate days. The FMDV 3D pan-serotype rRT-PCR assay (FMDV) was run in parallel with each replicate to ensure the presence of the FMDV template (D). Replicate Cq values are plotted with a black line representing the mean and error bars with the corresponding FMDV serotype color (SAT1 = yellow, SAT2 = purple, SAT3 = orange and FMDV 3D pan-serotype = green).
