Trend accuracy
Trend accuracy explains how well G7 captures the time-dependent characteristics of
glucose fluctuation. The following examples quantify G7's trend accuracy:
1. When the G7 rate of change is rapidly rising (> 2 mg/dL/min), how often is
reference glucose also trending up (>0 mg/dl/min)? The answer is 96.0% of
the time for adults and 94.2% for pediatrics.
2. When the G7 rate of change is rapidly falling (< -2 mg/dl/ min), how often is
reference glucose also falling (< 0 mg/dl/ min)? The answer is 89.9% of the
time for adults and 92.9% for pediatrics.
3. When the G7 rate of change is stable (≥ -1 mg/dL/min and ≤ 1 mg/dl/ min),
how often is reference glucose changing rapidly (> 2 mg/dL/min or < -2
mg/dl/ min)? The answer is only 1.9% of the time for adults and 1.3% for
pediatrics.

Questions and answers
Dexcom G7 continues to show readings 50 or 60 points higher than when I stick my finger and use the supplied recorder. Why?
The Dexcom G7 may show readings 50 or 60 points higher than fingerstick measurements due to several reasons:
1. Sensor's First Day: Newly inserted sensors may show larger differences, which usually decrease over the first 24 hours.
2. Pressure on Sensor: If something is pressing on the sensor (e.g., lying on it), it can affect readings. Removing the pressure can help.
3. Rapid Glucose Changes: Blood glucose changes before interstitial fluid glucose, so fast changes can cause differences between meter and sensor readings.
4. Fingerstick Issues: Inaccurate fingerstick readings can occur if hands are not washed properly or test strips are expired or used incorrectly.
These factors can cause temporary differences between Dexcom G7 and fingerstick readings.
