Comparison among different DENV detection assays for 153 clinical samples.
| Methods | NS1 antigen assay | RT-PCR | The conventional RT-LAMP | Total | Positive rate (%) | |||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Items | Pos. | Neg. | Concordance rate (%) | Pos. | Neg. | Concordance rate (%) | Pos. | Neg. | Concordance rate (%) | |||
| The novel mismatch- | Pos. | 136 | 9 | 90.8% | 116 | 29 | 78.4% | 133 | 12 | 92.2% | 145 | 94.8% |
| tolerant RT-LAMP | Neg. | 5 | 3 | 4 | 4 | 0 | 8 | 8 | ||||
| Total | 141 | 12 | NA | 120 | 33 | NA | 133 | 20 | NA | 153 | NA | |
| Positive rate (%) | 92.2% | NA | 78.4% | NA | 86.9% | NA | NA | NA | ||||
The concordance rate was calculated using the formula: (number of consistent results by both methods/total number) × 100%. Please also see the Venn diagram in Supplementary Figure S3 for details. Pos., positive; Neg., negative; NA, not applicable.
