The optimization results for the diagnosis of SARS-CoV-2. (a) The threshold time as a function of the different groups of primers with different concentrations of targets. The targets in three different concentrations, including low concentration (107 copies/mL), middle concentration (108 copies/mL), and high concentration (109 copies/mL) were recorded based on different sets of primers. The data are expressed as the (). (b) Temperatures ranging from 50°C to 68°C for the RT-LAMP reactions were optimized using 105 copies/mL of targets with gel electrophoresis.
