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.
When you see the symbol during the first 12 hours of wearing a Sensor
During the first 12 hours of Sensor wear the symbol will display, and you cannot
use Sensor values to make treatment decisions during this time. Confirm Sensor
glucose readings with a blood glucose test before making treatment decisions
during the first 12 hours of Sensor wear when you see the symbol.
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
There may be times when your symptoms don’t match your Sensor glucose
readings. For example, you are feeling shaky, sweaty, and dizzy – symptoms 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.
When to do Nothing and Check Again Later
Your health care professional can help you understand when doing nothing and
checking again later is the right treatment decision. For example, if your glucose is
high and going up, your first instinct may be to take more insulin to lower your
glucose, however depending on when you last took insulin or your recent activity,
