Repeatability of the LFD-RPA assay. a Inter-assay repeatability test: The standard control plasmids, at concentrations 1 × 108, 1 × 105 and 1 × 102 copies/μL (lane 1–3), were detected in three rounds under the same conditions. b Intra-assay repeatability test: The standard control plasmids, at concentrations 1 × 108, 1 × 105 and 1 × 102 copies/μL, repeat three tests at the same time under the same conditions. The top line on the lateral flow dipstick is the control line, and the next line is the test line
