Results of Freestyle's analytical accuracy in the low (BG < 100 mg/dL) and high glucose range (BG ≥ 100 mg/dL) before and after DKA resolution
| Before DKA resolution | After DKA resolution | |
|---|---|---|
| Low glucose range (BG <100 mg/dL) | ||
| n | 5 | 21 |
| MAD (mg/dL) | 34.0 | 22.7 |
| Percent of values within ±15 mg/dL of the BG value | 0% (0/5) | 42.9% (9/21) |
| High glucose range (BG ≥100 mg/dL) | ||
| n | 224 | 235 |
| MARD (%) | 19.7 | 17.2 |
| mARD (%) | 18.2 | 13.7 |
| MRD (%) | −3.5 | −6.0 |
| Percent of values within ±15% of the BG value | 43.8% (98/224) | 53.6% (126/235) |
Abbreviations: BG, blood glucose; DKA, diabetic ketoacidosis; MAD, mean absolute difference; MARD, mean absolute relative difference; mARD, median absolute relative difference; MRD, mean relative difference.
