3 Steps to Apply Sensor

Sensors stick better when you wash, clean, and dry your arm before application.

01 Wash, Clean, and Dry

Select a site on the back of your upper arm

that stays ﬂat during normal activity. Clean

skin with non-moisturizing, fragrance-

free soap and water. Use an alcohol wipe

to disinfect the skin and let air dry before

proceeding. Tip: Do not use moisturizer

where you apply the sensor.

02 Prep Applicator

Open sensor by peeling back the lid.

Unscrew cap from the sensor applicator.

Line up marks on the sensor applicator.

Press down ﬁrmly and then lift.

The FreeStyle Libre 2 system is designed to stay on for up to 14 days.

• Secure sensor by pressing it down and running your ﬁnger along the sensor adhesive.

• Apply sensor to dierent sites each time to avoid irritating your skin.

• Avoid placing sensor on moles, scars, stretch marks, and lumps. Shave hair on arm,

if necessary.

03 Apply

Apply the sensor to the back of your

upper arm by pressing ﬁrmly. Listen for

the click. Wait 30 seconds and pull back

slowly, leaving the sensor on the skin.

Tips to Help Keep

Your Sensor in Place

Some people use the following products for extra stickiness and protection:*

Torbot Skin Tac™

Hypoallergenic and

latex-free “tacky” skin barrier

Skin-Prep™ Protective

Barrier Wipe

Protective liquid dressing that

allows skin to breathe so tapes

and ﬁlms adhere better

Mastisol® Liquid

Adhesive

Clear, non-irritating, non-

water-soluble liquid adhesive

Tegaderm I.V.™

A transparent ﬁlm that

provides adhesive strength

Over-bandage†

Be sure to use only medical-grade adhesive, bandage, or tape.

Apply and remove at the same time you apply or remove your

sensor. Leave the opening/hole over the center of the sensor

uncovered so it can breathe.

Parent Tip

Because kids have smaller arms, it can be challenging to ﬁnd a new sensor

application spot. Make sure to rotate the site to allow skin to fully heal.

Switching arms each time can help.

Parent Tip

Experiment to ﬁnd extra stickiness products that work for your child.

Try an over-bandage for active kids.

4 Steps to Activate Sensor Scanning Tips

Follow these steps to be ready to get readings in just one hour. The more you scan, the more you know about your diabetes.

01 Turn on FreeStyle Libre 2 Reader

Hold your reader within 1.5 inches

of your sensor to scan right through

your clothes.*

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 you and your doctor

have to help manage your diabetes.

03 Scan with Reader

04 Let Sensor Warm Up for One Hour

Then you can start getting glucose readings.

Glucose Readings Learn from Your Data

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

don’t always appear (see Check Glucose Symbol below).

This symbol may appear if:

• Your sensor glucose is rapidly changing

• Your sensor glucose is low or going low

• LO or HI appears on the screen

• No trend arrow or glucose number appears

on screen

• You are in the ﬁrst 12 hours of sensor wear

Current reading What trend arrows mean:

110 Glucose is rising quickly

(more than 2 mg/dL per minute)

110 Glucose is rising

(between 1 and 2 mg/dL per minute)

110 Glucose is falling

(between 1 and 2 mg/dL per minute)

110 Glucose is falling quickly

(more than 2 mg/dL per minute)

A1c is useful because it measures your average glucose level over the past three months.

It’s helpful to look back at how you are managing your diabetes. But a good A1c doesn’t

mean your glucose is in control today. It doesn’t show your highs and lows or how your

blood glucose levels change throughout the day. This is where Time in Range can help.

If you see the symbol, do a

blood glucose test before

making treatment decisions.

READER SYMBOL

Access reports on the FreeStyle Libre 2 reader.

Check Glucose Symbol

Time in Range is the percentage of time you stay

within your target glucose range. You work with

your healthcare provider to determine a target

range goal. Your progress is then tracked in a

Time In Target report.

Use Alarms for Extra Safety

The FreeStyle Libre 2 system has optional, real-time glucose alarms* to help keep

you safe, even at night. Alarms are on by default and can be customized. Alarms

feature preset tones, a vibration option, and adjustable volume. To receive alarms,

your reader should be within 20 feet of you and unobstructed at all times. If you

are out of range, you may not receive glucose alarms.

Customize Alarms

Alarms are easyto set based on your target glucose goals.

Reference: 1. Data on ﬁle. Abbott Diabetes Care. 2. Please see the FreeStyle Libre 2 User’s Manual for complete instructions. 3. 70 mg/dL is the default Low

Glucose Alarm level and can be set between 60–100 mg/dL. 240 mg/dL is the default High Glucose Alarm level and can be set between 120–400 mg/dL.

*Notiﬁcations will only be received when alarms are turned on and the sensor is within 20 feet of the reading device.

Remove & Replace Sensor

Replace Sensor

Remember to choose a dierent spot on the back

of your upper arm to apply the new sensor. This

will help avoid skin irritation. See page 4 for

application instructions.

Sensor Disposal: The sensor should be disposed of in accordance with all applicable local

regulations related to the disposal of electronic equipment, batteries, sharps, and materials

potentially exposed to body ﬂuids. Contact Customer Service for more information.

The sensor is designed to stay on for up to 14 days. Here’s how to remove, replace,

and properly dispose of system components.

Tips for Wearing Your Sensor

Clothing:* Scan right through

your clothes. Be careful when

dressing to avoid disturbing

the sensor.

Showering, bathing, and

swimming:†Sensor is water-

resistant. Do not submerge more

than 3 feet or keep under water

longer than 30 minutes at a time.

Gently pat dry after getting it wet.

Exercising: Use skin adhesive

if sweating loosens sensor.

Try an over-bandage if

playing contact sports.

Traveling: System is safe to

use while on an aircraft. Do not

expose the sensor to airport

full-body scanners. Request

another type of screening to

avoid removing your sensor.

Medical procedures: Notify

your healthcare provider and

remove your sensor when

necessary. Exposing the sensor

to MRI, CT scan, diathermy, or

X-ray may cause damage and

incorrect readings.

Some good-to-know ideas about using CGM throughout your day.

*The reader can capture data from the sensor when it is within 1 cm to 4 cm of the sensor.

†Sensor is water-resistant in up to 1 meter (3 feet) of water. Do not immerse longer than 30 minutes.

Dierent and Accurate

CGM readings are taken

from interstitial ﬂuid, a

thin layer of ﬂuid that

surrounds the cells below

your skin.

Blood glucose readings

are taken from blood

with ﬁngersticks.

FPO

The CGM Dierence

There are times when your CGM and BGM readings may be dierent.

CGM measures interstitial ﬂuid glucose not blood glucose.

CGM systems give you a look at where you were, where you are, and where you’re headed.

You can trust your sensor glucose numbers and can feel conﬁdent in your results to

make treatment decisions. The FreeStyle Libre 2 system is approved for insulin dosing

without ﬁngersticks.*

CGM is dierent from blood glucose monitors (BGM) and proven to be accurate,

with fewer ﬁngersticks.*

These include when:

• Your glucose is changing rapidly; scan

shows a trend arrow (see diagram, page 11)

• Your ﬁngers were not washed before you

performed a ﬁngerstick test

• You took more than 500 mg of vitamin C

(ascorbic acid)

• Blood glucose strips were expired

or contaminated

• The ﬁngerstick check and sensor scan

were not performed at the same time

• It is the ﬁrst day wearing your sensor

• The sensor was bumped and is not ﬁrmly

attached to the back of your upper arm

*Fingersticks are required if your glucose alarms and readings do not match symptoms or when you see Check Blood Glucose symbol during the ﬁrst 12 hours.*Fingersticks are required for treatment decisions when you see Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect

readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.

Reference: 1. FreeStyle Libre 2 User’s Manual.

Dierence Between CGM and BGM Readings

CGM and BGM

readings are often

similar when stable.

Rapidly changing levels, like after a meal or exercise, can

cause a lag between your CGM and BGM readings.

For most people, the lag

is about 5–10 minutes.

That’s normal.

Glucose enters your blood stream ﬁrst

before it enters the interstitial ﬂuid.
