Flash glucose monitoring is a user-friendly way to discreetly obtain glucose readings. A flash glucose monitoring system provides a complete picture showing the current glucose reading plus you can see how glucose levels are changing in a flash by just scanning the reader over the sensor.
What makes flash glucose monitoring system unique is that a quick scan of the reader over the sensor provides a complete picture of your glucose including the current glucose reading, 8 hour history and trend arrow showing if your glucose level is going up, down or staying steady.
What happens if the reader runs out of power? Do I lose glucose readings if the reader runs out of power?
The reader needs to be recharged if it runs out of power. The stored glucose readings on the reader are not lost. The reader should fully charge in approximately 3 hours if the battery is completely discharged.
With normal use, the reader can be used for approximately 7 days before it needs to be recharged. A low battery warning will appear on the reader when it needs to be recharged. There is a battery icon on the reader which will indicate battery life.
Yes, you can get glucose readings through clothing by scanning the reader over the sensor. The reader can capture data from the sensor when it is within 1cm to 4cm of the sensor.
Is there any chance of overlapping glucose readings if I scan the reader over the sensor multiple times during an 8-hour period?
The reader is smart enough to figure out what data is new with each scan and not double-count any data.
In the UK, the only language available is English.
The reader display timeout is 60 seconds (120 seconds from when a test strip is inserted).
The reader storage temp is -20 °C to 60 °C and the sensor should be stored at 4 °C - 25°C.
You can create up to 12 reminders.
There are 5 standard notes and 6 custom notes that you can create for a total of 11 notes.
Median - is where half the readings fall below the line and half the readings fall above.
25th to 75th Percentile - is where 25%- 75% of the observed sensor glucose readings fall (or the middle 50% of results).
10th to 90th Percentile - is where 10% - 90% of the observed sensor glucose readings fall
The Ambulatory Glucose Profile (AGP) graph, found on several reports, provides a visual reference for changing glucose levels over time. Sensor glucose data of 5 days or more are combined and plotted into a single 24-hr chart. By plotting data this way, you can see patterns of variability that may be common to a specific time of day.
eA1c is an estimated value for HbA1c based on the average sensor glucose over the timeframe selected. eA1c is calculated using a formula from the published reference below*. eA1c is not meant to replace or predict the HbA1c tested in a laboratory. Instead you can use this value to monitor changes to eA1c over time.
* Nathan DM, Kuenen J, Borg R, et al. Translating the HbA1c assay into estimated average glucose values. Diabetes Care . 2008;31:1473-1478.
Consult the software user’s manual or your healthcare professional if you are having difficulty understanding or using the reports.
The FreeStyle Libre flash glucose monitoring system typically offers a Trend Arrow with each glucose reading which tells you which way and how quickly glucose levels are changing. So, at any given time, you not only know what your glucose level is currently, but also which way it is heading. Depending on the direction of Trend Arrow, you can find out if your glucose levels are going up, down or staying steady, facilitating better decision-making.
Traditional blood glucose monitoring provides users with glucose readings that represent distinct points in time. Users do not get information regarding how their glucose levels have been changing, nor do they get information about where their glucose levels are heading. Without such information, it can be easy to miss significant glucose fluctuations - the ups and downs. The FreeStyle Libre system is an innovative way to obtain glucose readings. It allows the user to get their current glucose reading by just scanning the reader over the sensor, and also provides a complete picture of glucose variations. For a complete glycemic picture, scan once every 8 hours.
You can use the built-in meter to check your blood ketone levels using FreeStyle Optium β ketone test strips (available on prescription). You should perform a blood ketone test on your fingertip only. Be sure to read the test strip instructions for use prior to using the built-in meter.
'Easy setup' is for users who use a fixed dose of rapid-acting insulin before meals. 'Advanced setup' is for users who count carbohydrates (in grams or servings) and/or use a correction factor to adjust doses of rapid-acting insulin at meals. The insulin calculator must be set up by a healthcare professional.
No, the insulin calculator can assist you with calculating rapid-acting (meal-time or short-acting) insulin doses only. The insulin calculator must be set up by a healthcare professional.
The insulin calculator utilises settings entered into the insulin calculator during one of two setup modes (Easy or Advanced); this feature requires an understanding of the use of insulin and must be set up by a healthcare professional. Using the settings they enter, the glucose reading from the built-in blood glucose meter and carbohydrate information (in grams or servings) the user provides, the insulin calculator software in the reader calculates a suggested insulin dose.
Yes, the system can calculate a suggested mealtime insulin dose when using the built-in blood glucose meter since it has a built-in insulin dose calculator function.
Please note that this feature only works when using the blood glucose test strip port and needs to be activated by a healthcare professional.
The sensor is approximately 5mm in height and 35mm in diameter. The portion of the sensor that gets inserted under the skin is less than 0.4 mm wide and it's inserted only about 5mm under the skin. In a study conducted by Abbott Diabetes Care, users agreed that inserting the sensor was no more painful than a typical finger prick glucose test*.
*Data on file. Abbott Diabetes Care.
The sensor automatically measures glucose levels every minute and stores readings at 15-minute intervals for 8 hours. When the sensor is scanned by the reader, the sensor automatically transmits 8 hours of data to the reader.
If the sensor is storing glucose readings every 15 minutes, does that mean I will get the same glucose reading if the sensor is scanned again within the same 15 minute interval?
No, you will get the most current reading every time you scan the reader over the sensor.
You can scan as often as you want, but the reading will never change more frequently than every 60 seconds.
To keep the sensor profile small it has a limited storage capacity. To make sure it could hold 8 hours of data (for a typical overnight period).
The sensor is applied on the back of the upper arm with a disposable device called an applicator. When the sensor is applied, a small (5mm) sterile filament is inserted just under the skin, and held in place with a small adhesive pad. In a study conducted by Abbott Diabetes Care, most users agreed that inserting the sensor was no more painful than a typical finger prick glucose test*.
*Data on file. Abbott Diabetes Care.
The disposable sensor is designed to adhere to the back of the upper arm and provide accurate glucose readings for up to 14 days. After 14 days, remove the sensor by peeling off the adhesive pad.
The sensor can only be worn on the back of the upper arm.
The portion of the sensor that gets inserted under the skin is less than 0.4 millimetre wide (1mm is about the thickness of a few strands of human hair) and it’s inserted only about 5mm under the skin, so most people will never feel the sensor while it is being worn. In a study conducted by Abbott Diabetes Care, most users agreed that they did not feel any discomfort under the skin whilst wearing the FreeStyle Libre sensor*.
*Data on file Abbott Diabetes Care
You can take as many glucose readings as you want while the sensor is being worn. In order to get a 24-hour glycemic picture you need to scan at least once every 8 hours.
Yes, the accuracy of the sensor remains consistent for up to 14 days.
A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycaemia or impending hypoglycaemia is reported by the System or when symptoms do not match the System readings.
Yes. The sensor can be worn while bathing, showering, swimming or exercising. The sensor should not be taken below a depth of 1 metre (3 feet) in water, and should not be submerged in water for more than 30 minutes.
Check with airline prior to departure as rules and regulations may change without notice.
After 14 days of wear, the reader notifies you. The time to the end of the sensor wear period is shown on the screen of the reader when you switch it on. After the wear period, the sensor will stop working and should be replaced with a new sensor.
Start a new sensor. The reader will identify that it is a new sensor and ask if you want to start it.
To check the system is working simply switch on the reader and scan over the sensor to get a glucose reading. If for any reason, the sensor does not work, an error message will appear on the reader prompting the user to replace the sensor.
If you have symptoms that do not match the FreeStyle Libre system reading or suspect your reading may be inaccurate, check the reading by conducting a finger prick test using a blood glucose meter. For convenience, there is a built-in blood glucose meter within the reader that can be used for blood glucose readings. If you are experiencing symptoms that are not consistent with your blood glucose readings, consult your healthcare professional.
For full details please refer to the FreeStyle Libre system User Manual.
What happens to the sensor if it is worn when it's warmer or colder than the recommended temperature range?
If the sensor stops working due to extreme temperature, the user will get an error message indicating 'Glucose Reading unavailable'.
This product 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.
This means the used applicator and sensor pack should be disposed of in a Biohazard Sharps bin - Clinical waste referral is required from the district nurse or GP, but the majority of people with diabetes will already have the necessary arrangements in place. The used sensor should be removed and wiped down with disinfectant, and then dispose of as electrical waste (the same as a battery).
No, the FreeStyle Libre sensor is calibrated during the manufacturing process so you don't have to. The sensor is activated by scanning and then, after a 1 hour warm up period, it starts to record glucose readings automatically.
Abbott Diabetes Care is committed to making its products safe for the user. After the insertion, the sensor and the body need to equilibrate (or settle). We have found through our research that it is not always easy to accurately measure glucose in the body until this equilibration happens. Therefore, we let the system equilibrate for 1 hour to make sure that it is providing accurate glucose readings.
‘Flash’ reflects the fact that users can obtain glucose readings quickly by just scanning the reader over the sensor*. Flash glucose monitoring also provides a flash of insight to people with diabetes and their health care professionals.
*A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels, or if hypoglycemia or impending hypoglycemia is reported or the symptoms do not match the system readings.
The FreeStyle Libre reader and the FreeStyle Libre sensor can be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors. You can keep your FreeStyle Libre sensor on while going through these.
However, the FreeStyle Libre reader and the FreeStyle Libre sensor should not be exposed to some airport full-body scanners (i.e. x-ray and millimeter radio-wave). To avoid removing your FreeStyle Libre sensor, you should request another type of screening to be performed by the Security Officer.
If in doubt about the type of security scan you are passing through, notify the Security Officer prior to proceeding through the airport security checkpoint.

If I use both the FreeStyle Libre reader and the LibreLink mobile app, what data will appear in LibreView
LibreView uses only the data from the device that was last used to scan your sensor. You can switch devices from the Available Meters window.
The FreeStyle LibreLink app is a mobile medical app designed to work with FreeStyle Libre sensors. The app enables you to monitor your glucose using your iPhone or Android phone* with a FreeStyle Libre sensor — there is no need to use a separate blood glucose meter for routine glucose monitoring.** When you scan the sensor with a compatible phone that’s running the FreeStyle LibreLink app, your glucose data is displayed directly on that device.
With the app you can:
• View your current glucose reading, a trend arrow, which indicates how your glucose is changing, and the last 8-hours of glucose history
• See glucose reports, including your Ambulatory Glucose Profile, which reveal trends and patterns
• Add notes to track your food, insulin use, exercise, and other events
• Connect to healthcare professionals and caregivers with LibreView and LibreLinkUp***
To use the FreeStyle LibreLink app, you must register with LibreView, a cloud-based diabetes management system provided by Abbott and Newyu, Inc.

Abbott Diabetes Care is now offering the FreeStyle LibreLink app as part of the FreeStyle Libre family of products. Like the LibreLink app, the FreeStyle LibreLink app enables patients to use their phone to scan their FreeStyle Libre sensor to help them manage their diabetes. Starting in 2018, the FreeStyle LibreLink app will become the only official app for use with the FreeStyle Libre flash glucose monitoring system. Current LibreLink app users are encouraged to transition to the FreeStyle LibreLink app as soon as possible, since support for the LibreLink app will be discontinued.
The FreeStyle LibreLink app includes several updates and new features in addition to many of the same features that already exist in the LibreLink app:
- Simple text-to-speech capabilities for readings, if enabled
- New sound and vibration settings for scans (Android)
- Ability to log insulin in 0.1 units
- Support for 26 total languages
After a transition period, the LibreLink app will no longer be supported or maintained. To continue using an active sensor with the new FreeStyle LibreLink app, current LibreLink app users should carefully follow the onscreen instructions in the LibreLink app to transfer data to the FreeStyle LibreLink app, once it’s installed. After a transition period, the LibreLink app will be removed from the Google Play Store. Please contact customer service if you need assistance transitioning from the LibreLink app to the FreeStyle LibreLink app.
No, the FreeStyle LibreLink app and the LibreLink app are the only apps that have been tested by Abbott Diabetes Care to be compatible with FreeStyle Libre sensors. The FreeStyle LibreLink6 and LibreLink apps4 were developed to ensure compliance with local regulations, including safety and performance requirements in accordance with the intended use. Any product that is intended to be compatible with FreeStyle Libre sensors would also need to comply with these regulations as well.

6 Use of the FreeStyle LibreLink app requires registration with LibreView, a service provided by Abbott and Newyu, Inc.
The thickness of the case can also make a difference. If your case is very thick on the back, it could prevent the NFC signal from reading the sensor.
NFC is the wireless communication technology that enables your FreeStyle Libre sensors to wirelessly transmit data to another device.
For Android users: Your Android phone must have NFC capabilities and NFC must be enabled. Many of the latest Android phones support NFC. Check your phone's manual or go to the phone’s Settings menu and look for settings related to 'NFC', 'Connections', 'Sharing', or 'Wireless and Networks'.
For iPhone users: You must have an iPhone 7 or higher running iOS 11 or higher to utilize the NFC capability needed to scan the FreeStyle Libre sensor.
Yes, with your permission, the app is able to share glucose data with certain other apps. View the Share menu within the FreeStyle LibreLink app to see what other apps are available for sharing in your region.
The app has the same indications for use as the FreeStyle Libre system.
After you’ve applied a FreeStyle Libre sensor to the back of your upper arm, open the app and hold the back of your Android phone near (exact distance will vary by phone) the FreeStyle Libre sensor to scan it. The size and location of the NFC antenna in Android phones varies by make and model, so you may have to move the phone around to find the best position for scanning the FreeStyle Libre sensor. Once you have found the optimal scan position, wait for the app to produce two distinct tones or vibrations before you move the phone away from the FreeStyle Libre sensor. The first tone indicates the phone’s NFC has recognized the sensor. The second tone indicates the scan is complete.
Once you have found the optimal scan position, wait for the app to produce two distinct tones or vibrations before you move the phone away from the FreeStyle Libre sensor. The first tone indicaiPhonetes the phone’s NFC has recognized the sensor. The second tone indicates the scan is complete.
After you’ve applied a FreeStyle Libre sensor to the back of your upper arm, open the app and tap one of the scan buttons within the app to put the iPhone in a scan ready state. There are two types of scan buttons – a blue button on the Home screen and a gray scan icon in the top right corner of most screens. Hold the top edge of your iPhone near the sensor and do not move your iPhone until you hear a tone and/or feel a vibration, which indicates the scan is complete.
You may or may not have to remove your phone case – it depends on the material that the case is made from, how thick the case is, and how well your phone’s NFC antenna works. If your phone case is made from plastic or silicone or another non-conductive material, you will probably be able to scan the sensor without removing the case. If the case is aluminum, metal or anything else that has a conductive surface, you may need to remove the case before scanning your sensor. The thickness of the case can also make a difference. If your case is very thick, it could prevent the phone from scanning the sensor.
Yes. The app was developed using the same technology that is in the FreeStyle Libre reader for receiving and processing glucose data, so it can also be used for routine glucose monitoring. The app can be used instead of or in combination with the FreeStyle Libre reader.
There’s no need to use a separate blood glucose meter for routine testing.* The app allows you to get glucose results as often as you like by simply scanning your FreeStyle Libre sensor with your phone. However, a fingerprick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels, if hypoglycaemia or impending hypoglycaemia is reported by the sensor, or when symptoms do not match the sensor readings.
*The FreeStyle LibreLink app and the FreeStyle Libre reader have similar but not identical features. A fingerprick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycaemia or impending hypoglycaemia is reported by the sensor or when symptoms do not match the sensor readings.
You can choose to monitor your glucose levels with either the app, the reader, or both.* You can use the FreeStyle LibreLink app and the FreeStyle Libre reader with the same sensor, as long as you start the sensor with the reader first, and then scan the newly started sensor with your phone within one hour.
Remember that the FreeStyle LibreLink app and FreeStyle Libre readers do not share data with each other. For example, if you switch between your reader and the app, you may see gaps in your glucose data, which will affect the reports available through the reader, the FreeStyle LibreLink app, and LibreView. It is important to continue scanning your sensor with either the app or the reader at least once every eight hours so you and your healthcare professional can get a complete picture of your glucose trends and patterns.
*The FreeStyle Libre sensor communicates with the FreeStyle Libre reader that started it, or the FreeStyle LibreLink app that started it. If you wish to use both the reader and the app, start your sensor with the reader first, then scan with the phone within one hour. Data is not synchronized between devices, so to ensure your reports include all available data choose one device that you will use to scan your sensor at least once every 8 hours.
The FreeStyle LibreLink app is intended to be used with only one sensor (and one person) at a time. Each app account is associated with one person. However, people who use the FreeStyle LibreLink app can connect with their caregivers if they are using a separate app called LibreLinkUp. LibreLinkUp allows caregivers to remotely monitor glucose readings performed by their love ones.
Yes. People with diabetes can use FreeStyle Libre sensors with the app to better understand the impact of actions like eating, exercise, and taking insulin based on their glucose levels. They can also make day-to-day therapy decisions when using the app with a FreeStyle Libre sensor, including insulin dosing decisions, based on guidance from their healthcare professional.
Yes. If you use an Android phone, you may need to go to your phone’s settings and reactivate NFC when your phone is in airplane mode. You can scan with your iPhone in airplane mode by tapping one of the scan buttons in the app to put it in a scan ready state.
Wi-Fi or a mobile data connection are only required for initial app setup (downloading / installing the app, creating an account, or signing in) and sharing your glucose information with your care team or with other connected apps. The app does not require a Wi-Fi or a mobile data connection to scan your sensor or to record your current glucose readings. During periods when your phone is operating in a disconnected state, your data will only be uploaded to LibreView after a Wi-Fi or mobile data connection is restored.
No, the FreeStyle LibreLink app is meant to be used as often as you like and should not have a noticeable effect on battery life beyond your normal usage patterns.
f your phone battery dies, charge your phone to continue using the FreeStyle LibreLink app. Your data will not be lost if the phone battery dies and you can scan the sensor while the phone is being charged..
