Diagnostic characteristics of the SLB ASF RDT using all sample types, and the performance using specific sample types.
| Sample type | DSe1 (%) [95% CI] | DSp2 (%) [95% CI] | PPV3 (%) | NPV4 (%) |
|---|---|---|---|---|
| All samples (n = 107) | 65 [51–77] | 76 [62–87] | 76 | 66 |
| Whole blood (n = 57) | 63 [44–80] | 85 [66–96] | 83 | 68 |
| Haemolysed serum (n = 36) | 50 [23–77] | 68 [45–86] | 50 | 68 |
| Non-haemolysed serum (n = 13) | NA | 83 [52–98] | 91 | NA |
