Glucose Readings
Q. Why is my sensor reading dierent from my blood
glucose meter reading?
A: The Eversense E3 CGM System measures glucose
in interstitial fluid (ISF) between the body’s cells.
Physiologic dierences between ISF and blood from
a fingerstick may result in dierences in glucose
measurements. These dierences are especially
evident during times of rapid change in blood glucose
(e.g., after eating, dosing insulin, or exercising), and
for some people, during the first several days after
insertion due to inflammation that may result from
the insertion procedure. On average, glucose levels
in ISF lag behind glucose levels in blood by several
minutes. Until you are aware of what these dierences
are, confirm sensor readings with a fingerstick blood
glucose check. Also, if your symptoms do not match
the sensor glucose readings, you should confirm with
a fingerstick blood glucose check.
Q: I am getting “-- -- --” in place of sensor glucose
readings on the app.
A: You may not get any sensor glucose readings
when there is no connection between your smart
transmitter and your sensor or smart transmitter
and mobile device.
You may also not get any readings when one of the
alerts below is activated:
