T108 | 0-73 | Sentence | denotes | Validation of the colorimetric RT-LAMP assay for SARS-CoV-2 RNA detection |
T109 | 74-182 | Sentence | denotes | To determine the specificity and sensitivity of the RT-LAMP assay, we continued to analyze more RNA samples. |
T110 | 183-258 | Sentence | denotes | We assayed a total of 768 RNA samples obtained on different days (fig. S1). |
T111 | 259-545 | Sentence | denotes | Visualization of the RT-LAMP assay results 30 min after the start of the incubation at 65°C showed comparable behavior of the samples in a total of ten 96-well test plates (Fig. 3A and Table 1), indicating that the RT-LAMP assay was reproducible from day to day and from plate to plate. |
T112 | 546-606 | Sentence | denotes | Fig. 3 Detection of SARS-CoV-2 RNA using the RT-LAMP assay. |
T113 | 607-732 | Sentence | denotes | (A) Scatter plot shows a comparison of RT-LAMP assay results and RT-qPCR results for RNA samples tested on 10 96-well plates. |
T114 | 733-847 | Sentence | denotes | The RNA extraction method (QC, QiaCube, a column-based method; QS, QiaSymphony, a bead-based method) is indicated. |
T115 | 848-963 | Sentence | denotes | The time point for measurement by the colorimetric RT-LAMP assay was 30 min after the start of the 65°C incubation. |
T116 | 964-1019 | Sentence | denotes | The 96-well plate shown in Fig. 2 is not included here. |
T117 | 1020-1245 | Sentence | denotes | Table 1 shows numbers of samples stratified according to the results of the RT-LAMP and the RT-qPCR assays. (B) Sensitivity (right) and specificity (left) of the RT-LAMP assay [derived from data in (A) and Table 1] are shown. |
T118 | 1246-1360 | Sentence | denotes | The specificity is the fraction of RT-qPCR–negative samples correctly identified as negative by the RT-LAMP assay. |
T119 | 1361-1654 | Sentence | denotes | For sensitivity, the RT-qPCR–positive samples were stratified by CT values into three bins (as indicated by x axis labels), and for each bin, the sensitivity is given as the fraction of qPCR-positive samples in the respective CT bin that have also given a positive result in the RT-LAMP assay. |
T120 | 1655-1896 | Sentence | denotes | The thick black lines indicate the values of these fractions (i.e., the specificity and sensitivity estimates); the black boxes indicate the corresponding 95% confidence intervals (Wilson’s binomial confidence interval). (See also table S2). |
T121 | 1897-2011 | Sentence | denotes | Table 1 Shown is RT-qPCR and RT-LAMP testing of 768 clinical samples stratified into CT value bins (see Fig. 3A). |
T122 | 2012-2103 | Sentence | denotes | Fig. 3B and table S2 show specificity and sensitivity values calculated from these numbers. |

T130 | 2238-2431 | Sentence | denotes | Sum 85 683 768 The consistency of the results during the analysis confirmed a threshold of ΔOD > +0.3 as a robust measure to identify samples that were positive for SARS-CoV-2 RNA (Fig. 3A). |
T131 | 2432-2631 | Sentence | denotes | RT-qPCR–positive samples with a CT < 30 scored positive in the RT-LAMP assay (79 of 81), whereas almost all samples with CT values between 30 and 40 scored negative (only 4 positive of 36) (Fig. 3B). |
T132 | 2632-2754 | Sentence | denotes | This confirmed the sensitivity of the RT-LAMP assay for detection of SARS-CoV-2 RNA in samples corresponding to a CT < 30. |
T133 | 2755-2913 | Sentence | denotes | We observed small differences between different plates on the exact sensitivity threshold, probably caused by slight variability in plate or reagent handling. |
T134 | 2914-3077 | Sentence | denotes | We found two RT-qPCR–negative samples that scored positive in the RT-LAMP assay (Fig. 3A and Table 1) and one sample that scored just below the ΔOD cutoff of +0.3. |
T135 | 3078-3166 | Sentence | denotes | The overall specificity of the RT-LAMP test was 99.7% (Wilson’s 95% confidence interval: |
T136 | 3167-3283 | Sentence | denotes | 98.9 to 99.9%), and the sensitivity for samples with CT < 30 on RT-qPCR was 97.5% (Wilson’s 95% confidence interval: |
T137 | 3284-3322 | Sentence | denotes | 91.4 to 99.3%) (Fig. 3B and table S2). |
