Why Can’t I Get Accurate Blood Sugar Readings?
Despite the advanced technology of the Freestyle Libre 2, there can be instances where you may not obtain accurate blood sugar readings. Here are some common reasons and how to address them:
1. Sensor Application Issues: Inaccurate readings can occur if the sensor is not properly applied to the back of your upper arm. Make sure to follow the instructions carefully and ensure it is securely attached.
2. Sensor Calibration: Unlike traditional glucose meters, the Freestyle Libre 2 does not require finger pricks for calibration. The readings are based on interstitial fluid, which may have a slight time delay in reflecting blood glucose levels accurately. Allow some time for the sensor to stabilize and align with your blood sugar levels.
3. Sensor Placement: The accuracy of the readings can be affected by the placement of the sensor. Avoid areas with significant adipose tissue or muscle. Consult the user manual or consult with your healthcare provider for proper sensor placement.
4. Temperature Extremes: Extreme temperatures can also impact the accuracy of the sensor’s readings. Avoid exposing the sensor to excessive heat or cold, as it can lead to inaccurate glucose measurements.
