What it may mean

If you have recently eaten, exercised, or taken insulin then you’ll need take a blood glucose test, as it is best to take a sensor reading during stable phases.

When glucose levels are falling quickly, glucose readings from the sensor may be higher than blood glucose levels. On the other hand, when glucose levels are rising quickly, glucose readings from the sensor may be lower than blood glucose levels.

What you can do

Do not ignore symptoms that may be due to low or high blood glucose. If you have symptoms that do not match the Sensor glucose reading or suspect that your reading may be inaccurate, check the reading by conducting a fingerstick test using a blood glucose meter.

The two readings should be taken no more than 10 minutes apart.

If you still see a potential accuracy issue once you have compared your sensor reading to a blood glucose reading, select continue.
