The FreeStyle Libre 2 flash glucose monitoring system is indicated for measuring interstitial fluid glucose levels in people aged 4 years and older with
diabetes mellitus. Always read and follow the label/insert.
The FreeStyle Libre 2 app and the FreeStyle Libre 2 reader have similar but not identical features. Finger pricks are required if readings do not match
symptoms or expectations. The FreeStyle Libre 2 sensor communicates with the FreeStyle Libre 2 reader that started it or the FreeStyle Libre 2 app
that started it. The FreeStyle Libre 2 app is only compatible with certain mobile devices and operating systems. Please check the website for more
information about device compatibility before using the app. Use of FreeStyle Libre 2 requires registration with LibreView.
* 60-minute warm-up required when applying the sensor.
† Sensor is water-resistant in up to 1 metre (3 feet) of water. Do not immerse longer than 30 minutes. Not to be used above 10,000 feet.
‡ Scanning the sensor does not require lancets.

Meet the
FreeStyle Libre 2 system
You can use EITHER the FreeStyle Libre 2 app OR
the FreeStyle Libre 2 reader to scan your sensor.
The FreeStyle Libre 2 app is free and easy to use!
To share glucose data and alarm notifications with others
using the LibreLinkUp app,* the FreeStyle Libre 2 sensor
must be paired with the FreeStyle Libre 2 app.
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.
* The LibreLinkUp mobile app is not intended to be a primary glucose monitor: home users must consult their primary device(s) and consult a
healthcare professional before making any medical interpretation and therapy adjustments from the information provided by the app.

Applying your sensor
Follow these four easy steps to apply your sensor:
1Select a site on the back of your upper arm, avoiding any scars, moles, or
lumps. Wash the area with plain soap (non-moisturizing, fragrance-free) and
water, and then dry.
2Use an alcohol wipe to disinfect the skin and allow the area to air-dry
before proceeding.*
3
Peel open the lid on the sensor pack and unscrew the cap from the sensor
applicator. Line up the dark marks on the sensor applicator and the sensor
pack. On a hard, flat surface, press down firmly on the sensor applicator until it
comes to a stop, and then lift to remove it from the sensor pack.†
4Apply the sensor by placing the applicator over the cleaned site and
pressing down firmly until the sensor is in place.‡Gently pull the sensor
applicator away from your arm and check that the sensor is secure.§
For complete application instructions, please see the product insert in the sensor kit.
* Choose a site that is at least 2.5 cm (1 inch) away from an insulin injection site. To prevent discomfort or skin irritation, you should select a different site other than the one most recently used.
† CAUTION: Do NOT use if the sensor pack or the sensor applicator seems to be damaged or already opened. Do NOT use if past expiration date. The sensor applicator now contains a needle. Do NOT touch inside the sensor applicator
or put it back into the sensor pack.
‡ CAUTION: Do NOT push down on the sensor applicator until placed over prepared site to prevent unintended results or injury.
§ Applying the sensor may cause bruising or bleeding. If there is bleeding that does not stop, remove the sensor and apply a new one at a different site. Make sure the sensor is secure after application.

Starting a new sensor
Follow these steps to activate your sensor and
connect it to your FreeStyle Libre 2 app or your
FreeStyle Libre 2 reader. You’ll be able to start
getting glucose readings after 1 hour.
1
Open the app or turn on the reader
The sensor can be paired
with only one device—choose
whether you’ll be scanning
with the app or the reader
2
Tap Scan new sensor

Scan your sensor
4
Your sensor will be ready
to scan in 1 hour
You’ll see a countdown on your
screen to let you know when
you can start scanning
Scanning your sensor
The more you scan, the more you know about your
glucose levels.
Did you know that people who scan more frequently
have improved control?
1
How to scan
Hold your device within 4 cm
of your sensor to scan right
through your clothes.*
Scan frequency
Scan at least once every
8 hours to avoid gaps in
your daily graph.
Key times to scan:
Before and after
meals or snacks
Before sleep and
after waking up
Before and after exercise
or other physical activity
When you feel symptoms
of low glucose
Data collected with the FreeStyle Libre system. The FreeStyle Libre 2 system has the same features as the FreeStyle
Libre system but with optional real-time glucose alarms. Therefore, study data are applicable to both products.
* The reader can capture data from the sensor when it is within 1 cm to 4 cm of the sensor.

How does the sensor work?
How does the sensor
measure glucose?
Skin
ISF Glucose Capillary
Cells
When you apply the FreeStyle Libre 2
sensor, a thin filament is inserted under
your skin and measures glucose levels.
What does the sensor measure?
The sensor measures the glucose levels
in the interstitial fluid (ISF)—a fluid that
surrounds the cells beneath your skin—
instead of blood glucose.
TIPS TO REMEMBER
It can take a few moments
for glucose to move from
blood to the ISF
Blood glucose readings
tend to be about 2 minutes
ahead of sensor readings1
Your trend arrow tells you
what direction your glucose
is heading
No confirmatory finger
pricks required, even when
glucose is low, falling, or
rapidly changing*
For illustrative purposes only. Image not drawn to scale.
* Finger pricks are required if readings do not match symptoms or expectations.

If I did a finger-prick test, would the results
match my sensor reading?
It’s important to remember that FreeStyle Libre 2 replaces blood
glucose monitoring,1,* and the two methods measure glucose
dierently. Because of the lag between blood glucose and sensor
glucose, your sensor reading may not always match a finger-prick
reading at a given moment. This example illustrates why:

Glucose levels
When glucose level is
trending down, the sensor
readings may be higher than
blood glucose readings
When glucose
level is stable, the
sensor readings
and blood
glucose readings
are similar
When glucose level is
trending up, the sensor
readings may be lower than
blood glucose readings
TIPS TO REMEMBER
It’s normal if your sensor
readings are dierent
from your blood glucose
readings in certain
situations (such as after
meals, insulin, or exercise)2,†
