Freestyle Libre 2 System Starter Kit
WELCOME TO THE FREESTYLE LIBRE 2 SYSTEM
The freedom to monitor your glucose without routine finger pricks, now with
optional glucose alarms
Visit MyFreeStyle.ca to access helpful videos and
tools
The FreeStyle Libre 2 lash 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 is required when applying the sensor.
† Sensor is water-resistant in up to 1 meter (3 feet) of water. Do not immerse longer than 30 minutes. Not to be used above 10,000 feet.
‡ Finger pricks are required if glucose readings and alarms do not match symptoms or expectations.
Meet the FreeStyle Libre 2 system
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 devices 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: 
Select 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. 
Use an alcohol wipe to disinfect the skin and allow the area to air-dry
before proceeding.* 
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, lat surface, press down firmly on the sensor applicator
until it comes to a stop, and then lift to remove it from the sensor pack.†
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 the sensor applicator
or put it back into the sensor pack.
‡ CAUTION: Do NOT push down on the sensor applicator until placed over the 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. 
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 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
When you feel symptoms of low glucose
Data was 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.

Understanding your scan
Use all four pieces of information to make treatment decisions: 
A Current glucose gives you an accurate glucose reading
B Glucose trend arrow shows you where your glucose is heading
| Glucose is rising rapidly
---|---
| Glucose is rising
| Glucose is changing slowly
| Glucose is falling
| Glucose is falling rapidly
C Glucose graph shows you an 8-hour history of your glucose
D Glucose message tells you if you’re in or out of range
How do I share my readings with others?
Our digital health tools work together for seamless management and keep
healthcare professionals, caregivers, and loved ones up to date on glucose
activity.

by-step instructions and videos.
LibreLinkUp
For caregivers or loved ones With the free LibreLinkUp mobile app, you can
invite family or caregivers to remotely monitor your glucose readings*and
receive alarm notifications. LibreView
For healthcare professionals
LibreView is a secure, cloud-based system that allows you to share your
glucose readings with healthcare providers. They can access and review all of
your information within
LibreView, making it easier for them to provide treatment support and offer
virtual consultations to you at home . Libre View

- 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.
How does the sensor work?
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 the blood to the ISF
---|---
| Blood glucose readings tend to be about 2 minutes ahead of sensor readings
| Your trend arrow tells you what direction your glucose is heading
| For most treatment decisions, sensor readings from the FreeStyle Libre
system can replace routine finger-prick tests*,†
For illustrative purposes only. Image not drawn to scale.
- A inger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial luid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the system or when symptoms do not match the system readings. † Treatment decisions should not be based on real-time sensor glucose readings alone but instead should consider all the information on the results screen.

If I did an 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 differently. 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: 
TIPS TO REMEMBER
| It’s normal if your sensor readings are different from your blood glucose
readings in certain situations (such as after meals, insulin, or exercise)
---|---
| For most treatment decisions, sensor readings from the FreeStyle Libre
system can replace routineinger-prick ests*, ‡
Data was 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.
- A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial luid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the system or when symptoms do not match the system readings.
† The delay between the sensor and blood glucose is about 5-10 minutes.
‡ Treatment decisions should not be based on real-time sensor glucose readings alone but instead should consider all the information on the results screen.
