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.

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

international organization created to produce
safety standards for electronics. One of the
safety standards it designed is the Ingress
Protection (IP) Marking, which classifies and
rates how protected an electronic device is
against dust, water, accidental contact, etc.
IP ratings are numerical, with the number based
on the conditions the electronic device comes
across.
An IP22 rating lets you know your electronic
device won’t allow you to stick your fingers in it
and won’t get damaged or be unsafe during
specific testing with water dripping down.
An IP28 rating tells you your electronic device
won’t let you stick your fingers in it and is safe for
long-term immersion in liquid up to a specified
pressure.
Jailbroken
The removal of limitations and security measures
set by the manufacturer on a smart device. The
removal poses a security risk and data may
become vulnerable.
Do not use, install or run the G5 Mobile app on a
jailbroken smart device. The app may not work
correctly on a jailbroken smart device.
Landscape
