Accuracy of the In Vivo Interstitial Fluid Ketone Sensor Results Compared to the Capillary Ketone Strip Reference. Table Reproduced from Alva et al. 1
| Concentration range | Percentage within | Mean MAD/MARD | SD/%CV | Number of paired data points | ||
|---|---|---|---|---|---|---|
| 0.225 mM/20% | 0.3 mM/30% | Between subject | Within subject | |||
| <1.5 mM | 83.4% | 91.7% | 0.129 mM | 0.051 mM | 0.029 mM | 2724 |
| ≥1.5 mM | 76.0% | 89.7% | 14.4% | 5.40% | 7.46% | 408 |
| Combined | 82.4% | 91.4% | – | – | – | 3132 |
Accuracy and bias results for ketone concentrations <1.5 mM are in mM. SD is the standard deviation and CV is the coefficient of variation.
