Overview of Parameters of Biological Variation
| Average Patient Concentration (ng/mL) | CVa (%) | CVi (%) | CVg (%) | II | RCV (%) | Log‐Normal | ||
|---|---|---|---|---|---|---|---|---|
| RCV Low (%) | RCV Up (%) | |||||||
| hs‐cTnI | 5.3 (3.7–8.3) | 5.0 | 14.0 | 94.1 | 0.16 | 38.7 | −33.6 | 50.5 |
| hs‐cTnT | 7.8 (5.1–11.1) | 3.0 | 18.1 | 75.9 | 0.24 | 50.1 | −39.6 | 65.5 |
CVa indicates analytical coefficient of variation; CVg, interindividual coefficient of variation; CVi, intraindividual coefficient of variation; Hs‐cTnI, high‐sensitivity cardiac troponin I; hs‐cTnT, high‐sensitivity cardiac troponin T; II, index of individuality; and RCV, reference change value.
