Troubleshoot: Extreme High/Low Readings During First 48 Hours
You are experiencing extreme high/low readings, and/or gaps in data within the first 48 hours or so of applying your sensor.
You should wait at least 48 hours to see if readings become more accurate by day 3 of wearing the sensor.
Why is this happening? It’s common for people to notice on the first day or two of wearing their sensor that the glucose values seem “off.” Some find that their values are reading unexpectedly high, and some see their glucose values concerningly low. This can create anxiety, but the key thing to know is that this is expected. The sensor needs a calibration period before its readings are considered accurate. Anecdotally, based on the experiences of our employees and early beta members, we have found that the sensor accuracy continues to improve over the first 48 hours so we recommend leaving sensors on for at least two full days.
Outcome: After 2+ days of wearing your sensor, the glucose readings should become more accurate. If after 2+ days you continue to have abnormally high or low readings, or see gaps in data, the sensor may be faulty.
