When When not not to use Sensor Glucose readings for treatment decisions to use Sensor Glucose readings for treatment decisions
No Current Glucose Number No Current Glucose Number
When there is no Current Glucose number, such as when you receive an error
message or a LO or HI result, you don't have enough information to make a
treatment decision. Do a blood glucose test and treat based on that result.
Think Your Readings are Incorrect? Think Your Readings are Incorrect?
Don't trust Sensor glucose readings that you think may be incorrect or that
don't match what you would expect based on your recent activity. For example,
if you ate dinner but forgot to take insulin before eating, you would expect your
glucose to be high. If your glucose reading is low, then it doesn't match your
recent activity, so don't use it to make treatment decisions. Don't make
treatment decisions if you think your Sensor glucose readings are incorrect. Do a
blood glucose test and treat based on that result.
Symptoms Don't Match Readings Symptoms Don't Match Readings
There may be times when your symptoms don't match your Sensor glucose
readings. For example, you are feeling shaky, sweaty, and dizzy – symptoms that
you generally get when you have low glucose, but your glucose reading is within
your target range. When symptoms don't match readings, do a blood glucose
test and treat based on that result. Don't ignore symptoms that may be due to
low or high blood glucose.
If you're the caregiver, pay attention to times when the symptoms of the one
you're caring for don't match their Sensor glucose readings. When symptoms
don't match readings, do a blood glucose test and treat based on that result.
If you continue to feel Sensor glucose readings are not correct, compare the
blood glucose result to the Sensor glucose reading. You'll know the Sensor is
performing correctly if these results are within 20% of each other (for example,
when the Sensor reads 10.0 mmol/L, the blood glucose result should be
between 8.0 and 12.0 mmol/L). If the blood glucose result is not within 20% of
the Sensor glucose reading, use a blood glucose meter instead of the Sensor
and try the check again later. If the problem continues, keep using the blood
glucose meter instead of the Sensor and contact your healthcare professional
for guidance on when you can use the Sensor.
