Table 2.
The proportion of faint band appearance, ParaCheck Pf® misdiagnosis with either positive or negative "faint band" classification, local microscopy misdiagnosis and true positives.
| ParaCheck® faint bands and misdiagnosis | Proportion |
|---|---|
| ParaCheck Pf® tests resulting in a faint band (n = 291) | 69 (23.7%) |
| ParaCheck Pf® positive (if classify faint as +) (n = 291) | 74 (25.4%) |
| ParaCheck Pf® positive (if classify faint as -) (n = 291) | 5 (1.7%) |
| ParaCheck Pf® Misdiagnosis (if classify faint as +) (n = 283) | 68 (23.4%) |
| ParaCheck Pf® Misdiagnosis (if classify faint as -) (n = 283) |
1 (0.35%) |
| Misdiagnosis with local microscopy (n = 283) | 131 (45.0%) |
| True positives determined by external QC (n = 283) | 6 (2.1%) |
| ParaCheck Pf® faint Bands corresponding with true positives* (n = 69) | 3 (4.3%) |
| ParaCheck Pf® faint Bands corresponding with true negatives* (n = 69) | 65 (94.2%) |
*True positives and true negatives were determined by external quality control
