Normal range definition of the STG‐DrugScreen application on the ST Genesia system using plasma sample from 42 healthy individuals
| Healthy (n = 42) | Lag time absolute | Peak height absolute | Time‐to‐peak absolute | ETP absolute | Lag time normalized (ratio) | Peak height normalized | Time‐to‐peak normalized (ratio) | ETP normalized |
|---|---|---|---|---|---|---|---|---|
| Mean | 0.93 min | 456.20 nmol/L | 2.03 min | 1418 nmol/L | 1.16 | 97% | 0.98 | 83% |
| SD | 0.09 min | 56.35 nmol/L | 0.16 min | 270 nmol/L | 0.10 | 12% | 0.08 | 15% |
| CV (%) | 9.8 | 12.4 | 7.9 | 19.1 | 9.6 | 12.1 | 7.9 | 18 |
| Minimum | 0.73 min | 355.90 nmol/L | 1.80 min | 1027 nmol/L | 0.81 | 75% | 0.87 | 56% |
| Maximum | 1.22 min | 571.40 nmol/L | 2.69 min | 1993 nmol/L | 1.33 | 120% | 1.29 | 118% |
| 10% | 0.82 min | 380.20 nmol/L | 1.87 min | 1122 nmol/L | 0.90 | 81% | 0.90 | 68% |
| 90% | 1.00 min | 538.90 nmol/L | 2.17 min | 1851 nmol/L | 1.11 | 115% | 1.29 | 109% |
All samples were tested on the same day, explaining the few differences in term of variability between absolute and normalized results.
Abbreviations: CV, coefficient of variation; ETP, endogenous thrombin potential; SD, standard deviation.
