TABLE 3.
Comparison between the percentage of discrepancies between the original results and the results after proficiency testing, as a function of the RLU valuea
| Categories of samples | Mean % (95% CI) probability of discrepancy |
|---|---|
| Proficiency testing | |
| RLU <0.5 | 0 (0) |
| 0.5 ≤ RLU < 1 | 9.59 (6.02–13.58) |
| 1 ≤ RLU < 10 | 9.87 (6.50–13.82) |
| RLU ≥10 | 0.41 (0–1.21) |
| Proposed proficiency testing | |
| RLU < 0.5 | 0 (0) |
| 0.5 ≤ RLU < 1 | 9.59 (6.02–13.58) |
| 1 ≤ RLU < 5 | 12.56 (7.64–18.47) |
| RLU ≥5 | 1.18 (0.30–2.87) |
