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.
Alternative Site
Testing
Using a blood sample from non-fingertip (alternate) 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, 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 Dexcom G5 Mobile App was developed as a display for
continuous glucose monitoring.
Blood Glucose (BG)
Value
BG is an abbreviation of blood glucose. Blood glucose value is the
amount of glucose in the blood measured by a BG meter.
Blood Glucose
Meter/Meter/BG
Meter
A blood glucose meter is a medical device used to measure how
much glucose is in the blood.
Calibration Calibration is 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 the sensor glucose reading is
on track.

Continuous Glucose
Monitoring (CGM)
Continuous glucose monitoring (CGM) systems use 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 Dexcom
G5 Mobile should not be used because it may be harmful to you.
The risk of use clearly outweighs any possible benefit.
Hyperglycemia High blood glucose. Same as “high” or high blood sugar.
Hyperglycemia is a characterized by an excess of glucose in
the bloodstream.
It’s important to treat hyperglycemia. If left untreated,
hyperglycemia can lead to serious complications.
The default high alert in the Dexcom G5 Mobile CGM System
is set to 200 mg/dL. Consult your healthcare professional to
determine the appropriate hyperglycemic setting for you.
Hypoglycemia Low blood glucose. 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 alert in the Dexcom G5 Mobile CGM System is set
to 80 mg/dL. Consult your healthcare professional to determine
the appropriate hypoglycemic setting for you.
Indications A condition making a particular treatment or procedure advisable.
How, for what purposes, and under what circumstances you
should use the Dexcom G5 Mobile CGM System. Indications let
you know who should use the Dexcom G5 Mobile CGM System
and when.

IP The International Electrotechnical Commission (IEC) is a nonprofit,
non-governmental, 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.
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 Dexcom G5 Mobile App on a
jailbroken smart device. The app may not work correctly on a
jailbroken smart device.
Landscape If your smart device is oriented sideways.
mg/dL Milligrams per deciliter. The standard unit of measure for glucose
readings in the United States.
Portrait If your smart device is oriented vertically.
Precaution A safety statement regarding any special care to be exercised by
you or your healthcare professional for the safe and effective use
of the Dexcom G5 Mobile CGM System.
RF Radio-frequency transmission used to send glucose information
from the transmitter to the receiver or smart device.
Safety Statement A statement of the intended uses of Dexcom G5 Mobile
CGM System and relevant warnings, precautions,
and contraindications.

reported every five minutes, with data being sent to your
display device(s).
Smart/Mobile
Device
A smart/mobile device is an electronic device that is
cordless (unless charging), mobile (easily transportable),
connected (via Wi-Fi, 3G, 4G, etc.) that can operate to some
extent autonomously.
Examples of smart/mobile devices are smartphones, tablets,
or phablets.
