A1C
Blood test used to diagnose type 1 or 2 diabetes
and to gauge how well you’re managing your
diabetes. The A1C test result reflects your
average blood sugar level for the past two to
three months.
Accessory Device
Hardware, connected to your smart device by
Bluetooth , you use to get easy access to some of
its features. For example,
Bluetooth headset,
Apple®watch, or smart watch.
Also called wearables.
Alternative Site Testing
Using a blood sample from non-fingertip
(alternative) sites such as the palm, forearm or
upper arm for meter readings.
Do not use alternative site testing to calibrate the
Dexcom G5®Mobile CGM System (G5 Mobile).
Only use fingerstick measurement.
App
A self-contained program or piece of software
designed to fulfill a particular purpose; an
application, especially as downloaded by a user
to a smart or mobile device.
The G5 Mobile app was developed as a display
for continuous glucose monitoring.
Apple Watch
®
Accessory device for iPhones®.
Blood Glucose (BG)
Value
An abbreviation of blood glucose. Blood glucose
(BG) value is the amount of glucose in the blood
measured by a BG meter.

Blood Glucose
Meter/Meter/BG Meter
A medical device used to measure how much
glucose is in the blood.
Calibration
A comparison or measurement between your
meter’s fingerstick BG values and the sensor’s
interstitial fluid glucose readings. Although blood
and interstitial fluids are similar, glucose
concentration is higher in your blood. Calibration
allows alignment between your sensor and meter
readings.
When you calibrate, you take a fingerstick
measurement from your meter then enter the
value into your receiver or smart device. The
system uses that value to verify that the sensor
glucose reading is on track.
Continuous Glucose
Monitoring (CGM)
A system that uses a sensor inserted under the
skin to check glucose levels in interstitial fluid. A
transmitter sends sensor glucose readings to a
display device.
Users must confirm glucose levels with a BG
meter before making a change in treatment.
Contraindication
A safety statement outlining specific situations
where the G5 Mobile should not be used
because it may be harmful to you. The risk of use
clearly outweighs any possible benefit.

glucose in the bloodstream.
It’s important to treat hyperglycemia. If left
untreated, hyperglycemia can lead to serious
complications.
The default High Glucose Alert in the G5 Mobile
is set to 200 mg/dL. Consult your healthcare
professional to determine the appropriate
hyperglycemic setting for you.
Hypoglycemia
Low BG. Same as “low” or low blood sugar.
Hypoglycemia is characterized by a low level of
glucose in the bloodstream.
It’s important to treat hypoglycemia. If left
untreated, hypoglycemia can lead to serious
complications.
The default Low Glucose Alert in the G5 Mobile is
set to 80 mg/dL. Consult your healthcare
professional to determine the appropriate
hypoglycemic setting for you.
