T198 0-217 Sentence denotes On the basis of these preliminary experiments, we decided to use swab samples either directly without any treatment (direct swab–to–RT-LAMP assay) or after heat treatment for 5 min at 95°C (hot swab–to–RT-LAMP assay).
T199 218-329 Sentence denotes As an additional precaution, we kept the samples in the cold (using an ice-cold metal block) whenever possible.
T200 330-437 Sentence denotes For testing large numbers of clinical samples, we performed the RT-LAMP assay using several 96-well plates.
T201 438-596 Sentence denotes In total, we tested 209 different samples using the hot swab–to–RT-LAMP assay, and of these, 131 samples also were tested by the direct swab–to–RT-LAMP assay.
T202 597-744 Sentence denotes Many samples were tested twice but using aliquots withdrawn at different time points (usually within 24 hours) from the swab samples stored at 4°C.
T203 745-865 Sentence denotes This resulted in 235 direct swab–to–RT-LAMP assay measurements and 343 hot swab–to–RT-LAMP assay measurements (Fig. 5A).
T204 866-1108 Sentence denotes The hot swab–to–RT-LAMP assay detected a color change in the majority of samples with a CT < 30 with high sensitivity, whereas the direct swab–to–RT-LAMP assay only exhibited a high sensitivity for samples with a CT < 25 (Fig. 5 and Table 3).
T205 1109-1253 Sentence denotes The heat treatment rendered the RT-LAMP assay more stringent as it reduced false positives and more sensitive for samples with a CT of 25 to 30.
T206 1254-1358 Sentence denotes We found that some positive samples did not induce a color change but did so when assayed a second time.
T207 1359-1434 Sentence denotes We therefore would recommend running this assay using technical duplicates.
