Table 2 Intermediate precision by method validation
Validation | Concentration (μg/mL) | Measured conc. (μg/mL) (95% CI*) | Precision (RSD, %) | Accuracy (%) (95% CI*) | |
|---|---|---|---|---|---|
Intra-day (n = 6) | 500.0 | 494.8 ± 1.5 | 0.4 | 99.0 ± 0.3 | |
Inter-day (n = 3) | Day 1 | 500.0 | 495.7 ± 3.4 | 0.6 | 99.1 ± 0.6 |
Day 2 | 500.0 | 496.5 ± 1.8 | 0.3 | 99.2 ± 0.3 | |
Day 3 | 500.0 | 494.7 ± 7.7 | 1.4 | 98.9 ± 1.5 | |
