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.
