*Data from this study was collected with the outside US version of Freestyle Libre 14 day system. Freestyle Libre 2 has the same features
as Freestyle Libre 14 day system with optional, real-time glucose alarms. Therefore, the study data is applicable to both products. †The
FreeStyle Libre 2 app is only compatible with certain mobile devices and operating systems. Please check our website for more information
about device compatibility before using the app. Use of the FreeStyle Libre 2 app requires registration with LibreView. ‡The LibreLinkUp app
is only compatible with certain mobile device and operating systems. Please check www.librelinkup.com for more information about device
compatibility before using the app. Use of the LibreLinkUp app requires registration with LibreView. LibreLinkUp is not intended to be used for
dosing decisions. The user should follow instructions on the continuous glucose monitoring system. LibreLinkUp is not intended to replace
self-monitoring practices as advised by a physician. §The FreeStyle Libre 2 app and the FreeStyle Libre 2 reader have similar but not identical
features. Fingersticks are required for treatment decisions when you see Check Blood Glucose symbol and when your glucose alarms and
readings from the system do not match symptoms or expectations. || Notifications will only be received when alarms are turned on and the
sensor is within 20 feet unobstructed of the reading device. You must enable the appropriate settings on your smartphone to receive alarms
and alerts, see the FreeStyle Libre 2 User’s Manual for more information.

4 Steps to Apply Sensor
Sensors stick better when you wash, clean, and dry your
arm before application.
01 Selecting a Sensor Site
Select an area on the back of your upper arm that generally
stays flat (no bending or folding). Choose a site that is at least
1 inch (2.5 cm) away from an insulin injection site. Prevent
discomfort or skin irritation by selecting a site other than the
one most recently used. Make sure the site is clean-shaven to
avoid interference with the sensor.
02 Preparing the Skin’s Surface
Only use non-moisturizing, fragrance-free soap to wash the area
where you’ll apply the sensor. Use the alcohol wipe provided in
the sensor kit to remove any oily residue. Allow your skin to
fully dry before applying the sensor. This is especially important
if you plan to apply the sensor after you shower or swim.

Pg 7 of 32
03 Preparing the Sensor
Peel lid from the sensor pack and unscrew cap from the sensor
applicator. Line up marks on the sensor applicator and pack.
Press down firmly on the sensor applicator until it comes to
a stop. Lift the sensor applicator out of the sensor pack. The
sensor applicator is now ready to apply the sensor.
04 Applying the Sensor
Place the sensor applicator over the application site, press firmly,
and hold for a few seconds. Gently pull the sensor applicator away
from your body. Make sure the sensor is secure by pressing the
sensor down and running your finger along the sensor adhesive.
Get support and information at FreeStyleLibre.usGet support and information at FreeStyleLibre.us
Quick Tip
Make sure to rotate the site to allow skin to fully heal.
Switching arms each time can help.
CAUTION: Sensor applicator
will now contain a needle.
Do not touch inside sensor
applicator or place back
inside sensor pack.
NOTE: Sensor pack and
sensor applicator codes
must match or glucose
readings may be inaccurate.

Tips for Keeping Your
Sensor in Place
Easy Does It
Be careful not to catch your sensor on objects such as
doorways, car doors, seat belts, and furniture edges.
Play It Safe
For contact sports and heavy exercise, select a sensor site
on the back of your upper arm that minimizes the risk of the
sensor being knocked o. Consider using an overbandage
and/or other adhesive products listed on the front.
Hands O
Try not to play with, pull, or touch the sensor while
wearing it.
Pat Dry
After a shower or swim, take extra care when toweling o
to avoid catching or pulling o your sensor.
Dress for Success
Give your sensor room to breathe by wearing loose-fitting
clothing and lightweight materials.
Slow Down
When dressing or undressing, be careful not to catch
your undergarments on the sensor.
We're here to help. For further assistance with sensor adhesion,
please contact Abbott Customer Care at 1-855-632-8658.

Pg 11 of 32
How to Scan Your Sensor
Hold your smartphone* or reader within 1.5 inches of your
sensor to scan through your clothes.†
Tips for Scanning
The more you scan, the more you know about your
glucose levels.
Scan Frequently
Remember to scan at least once every 8 hours to avoid gaps
in your daily graph. The more you scan, the more complete
picture of your glucose levels you and your doctor have to help
manage your diabetes.
Key Times to Scan
Before & After Meals or Snacks
Before & After Exercise and Sporting Events
Before Sleep and After Waking Up
When You Feel Low Glucose Symptoms
*The FreeStyle Libre 2 app is only compatible with certain mobile devices and operating systems. Please check our website for more
information about device compatibility before using the app. Use of the FreeStyle Libre 2 app requires registration with LibreView. †The
reader can capture data from the sensor when it is within 1 cm to 4 cm of the sensor.

Pg 12 of 32
Understand Your Sensor
Glucose Readings
Sensor Glucose Screen
This screen shows your current glucose reading and a trend
arrow. With trend arrows, you can monitor the direction your
glucose is heading.
TIP: Trend arrows may not
always appear (see Check
Glucose Symbol below).
For illustrative purposes only. Not actual patient data.
The FreeStyle Libre 2 app is only compatible with certain mobile devices and operating systems. Please check our website for more
information about device compatibility before using the app. Use of the FreeStyle Libre 2 app requires registration with LibreView.
When you see this symbol during the first 12 hours of
wearing a sensor, confirm sensor glucose readings with a
blood glucose test before making treatment decisions.
In addition, do a blood glucose test if you think your readings
are not correct or do not match how you feel. Do not ignore
symptoms that may be due to low or high glucose.
Check Glucose Symbol

Pg 13 of 32
How to Interpret
Trend Arrows
You have probably noticed the trend arrow next to your
current glucose reading. Sometimes it points up, sometimes
sideways, and sometimes down. But what does it mean?
And how can it help you manage your glucose levels?
Current reading What trend arrows mean:
112 mg/dL Glucose is rising quickly
(more than 2 mg/dL per minute)
112 mg/dL Glucose is rising
(between 1 and 2 mg/dL per minute)
112 mg/dL Glucose is changing slowly
(less than 1 mg/dL per minute)
112 mg/dL Glucose is falling
(between 1 and 2 mg/dL per minute)
112 mg/dL Glucose is falling quickly
(more than 2 mg/dL per minute)
Medicare coverage is available for the FreeStyle Libre 2 system if a compatible smartphone is used in conjunction with the FreeStyle Libre
