COVID-19 Related Q&A
We are closely monitoring the COVID-19 situation across our business operations and we are working with local teams and relevant authorities as the situation evolves. At this time, there has been no impact on availability of Abbott’s diabetes care products in HongKong.
Our FreeStyle Libre Digital Ecosystem provides you with the FreeStyle LibreLink mobile phone app and LibreView, a secure cloud-based software that allows both you and your doctor to connect remotely at no cost. Please visit our website where it clearly shows how to download the FreeStyle LibreLink app, create a LibreView account, and how to set up data sharing with your doctor.
While LibreView is the best way to connect with your physician, you can also directly connect with your doctor using the FreeStyle LibreLink app via text or e-mail. Simply tap the share icon that’s displayed at the bottom of each report available within the APP.
In addition, remember that by using the LibreLinkUp app, you can invite your family/caregiver to also access your glucose data remotely, anytime. Visit https://librelinkup.com/ to see how to do this.
If you visit our web shop, you will see clear information and instructions related to the amount of sensors you’re able to order. At the moment, there is no plan to increase or decrease these options.
FreeStyle Libre Reader
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.
The oldest glucose readings will be lost if the reader is not scanned at least once during an 8 hour period. For example, if you scan the reader over the sensor at 1:00pm and again at 10:00pm, then you will lose glucose data from 1:00-2:00pm.
The reader is smart enough to figure out what data is new with each scan and not double-count any data.
The language on the reader is country-specific and therefore varies from country to country.
In Hong Kong, the language available is English
For most screens, the reader dims after 45 seconds. From a strip result, removing the test strip will turn off the display1.
1 For most screens, the reader dims after 45 seconds and turns off after 60 seconds. From a strip result, removing the test strip will turn off the display.
FreeStyle Libre Sensor
The sensor is 5mm in height and 35mm in diameter. The portion of the sensor that gets inserted under the skin is less than 0.4mm wide and it’s inserted only about 5mm under the skin. Studies indicate that a vast majority of users found the insertion no more painful than a typical finger prick glucose test1.
1 Most people did not feel any discomfort under the skin while wearing the FreeStyle Libre sensor. In a study conducted by Abbott Diabetes Care, 93.4% of patients surveyed (n=30) strongly agree or agree that while wearing the sensor, they did not feel any discomfort under their skin. [29 persons have finished the study; 1 person terminated the study after 3 days due to skin irritations in the area where the sensor touched the skin.]
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.
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), a 15 minute interval was chosen.
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. Applying the sensor feels similar to a finger stick2.
2. Rate your level of pain experienced using the Sensor Based Glucose Monitoring system. Most people did not feel any discomfort under the skin while wearing the FreeStyle Libre sensor. In a study conducted by Abbott Diabetes Care, 93.4% of patients surveyed (n=30) strongly agree or agree that while wearing the sensor, they did not feel any discomfort under their skin. [29 persons have finished the study; 1 person terminated the study after 3 days due to skin irritations in the area where the sensor touched the skin.]
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 worn3.
3. Most people did not feel any discomfort under the skin while wearing the FreeStyle Libre sensor. In a study conducted by Abbott Diabetes Care, 93.4 % of patients surveyed (n=30) patients agree that the FreeStyle Libre sensor is comfortable to wear.
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.
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.
Your sensor automatically stops working after 14 days.
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 FreeStyle Optium blood glucose meter within the reader which works with FreeStyle Optium blood glucose and blood ketone test strips4. If you are experiencing symptoms that are not consistent with your glucose readings, consult your health care professional.
4. For additional details please read the User Guide.
Move to a location where temperature is appropriate and scan again in a few minutes.

FreeStyle LibreLink App - General Information
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 phone1 with a FreeStyle Libre sensor — there is no need to use a separate blood glucose meter for routine glucose monitoring.2 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 LibreLinkUp3
To use the FreeStyle LibreLink app, you must register with LibreView, a cloud-based diabetes management system provided by Abbott and Newyu, Inc. Please see the product labeling for FreeStyle Libre and the FreeStyle LibreLink app for specific instructions on using the different products, including the supported age range.
Important: You must have a compatible iPhone or Android phone to install and use the app (See Compatibility Guide)
The app is designed to work with iPhones and Android phones that meet the following minimum requirements. You can also check the compatibility guide for additional information.
- iPhone models: iPhone 7 or higher
- Operating system: iOS 11 or higher
- Operating system: Android 5.0 (Lollipop) or higher
- Near-Field Communication (NFC): Your phone must have NFC capabilities and NFC must be enabled
Currently, there is no overarching legislation that regulates the sale and use of medical devices in Hong Kong.
No, the FreeStyle LibreLink app is the only app that has been tested by Abbott Diabetes Care to be compatible with FreeStyle Libre sensors. The FreeStyle LibreLink4 app was 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.
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 & 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.
Using the FreeStyle LibreLink app
The app has the same indications for use as the FreeStyle Libre system. Please see the FreeStyle Libre system indications for use for your country.
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.
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.2 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 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, 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 both7. 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.
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 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.
If 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.
The FreeStyle LibreLink app is not supported on rooted Android phones or jailbroken iPhones

- Text to Speech: If enabled in the app, you can hear the glucose reading with the unit of measure and trend arrow direction after each scan.
- Reports: The reader and the app use the same calculations to create glucose reports. Compared to the Reader, reports in the app will have more color, details, and interactivity. The app can also display an estimate of your A1c, in addition to basic stats about your glucose history in the last 24 hours.
- Reminders: The app allows you to easily set custom reminders, as well as an 8-hour timer that resets every time the sensor is scanned. App notifications on your phone must be enabled to see reminders.
- Other: The reader has a port for test strips, so it can be used both for scanning sensors and blood glucose readings.
FreeStyle LibreLink App - Reports
The app includes a series of reports that highlight your glucose trends and patterns. From the main menu select the report you wish to see.
- Daily Patterns: A graph showing the pattern and variability of the sensor glucose readings over a typical day. Includes the median, 25th -75th percentile, and 10th-90th percentile range of the glucose readings.
- Time in Target: A graph showing the percentage of time the sensor glucose readings were above, below, or within the Target Glucose Range.
- Low Glucose Events: Information about low glucose events measured by the sensor. A low glucose event is recorded when the sensor glucose reading is lower than 3.9 mmol/L (70 mg/dL) for longer than 15 minutes.
- Average Glucose: Information about the average sensor glucose readings for different periods of the day.
- Daily Graph: A graph of the sensor glucose readings by day.
- Estimated A1c: Estimate of A1c (HbA1c) based on sensor glucose data from the last 90 days. A1c can be used as an indicator of how well glucose levels have been controlled and may be used to monitor a diabetes treatment regimen.
- Sensor Usage: Information about how often the sensor is scanned.
A minimum of 5 days of sensor data is required for an estimated A1c to be calculated.
E-mail or text reports directly from the app by tapping the share icon that’s displayed at the bottom of each report available within the app. You can also show the reports on your phone to your doctor or nurse during your next appointment. LibreView may also be an option if your doctor has set it up for patients to share data (more information about LibreView below).
Data Management and LibreView
LibreView is a cloud-based diabetes management system provided by Abbott and Newyu, Inc. LibreView provides a secure repository for data from your FreeStyle LibreLink app, and allows you to easily share your glucose data with your healthcare professional or others, if you wish. Data is automatically6 uploaded to LibreView when your phone is connected to the Internet.
The app stores your account information, glucose data, notes, and sensor information within the app on your phone, so it is your responsibility to limit access to your phone to protect personal information. The app also automatically uploads this data in LibreView, a secure cloud-based data repository. Please read the Privacy Notice for more information.
If you lose your phone, download the app again on a compatible phone and sign in with your account information. If you have an active sensor and need to reinstall the app, when you sign into your existing account, you can continue using your active sensor until the end of its useful life. You will not be able to view historical data in the new installation of the app, but this data will be available in LibreView.
No, your glucose data from the FreeStyle LibreLink app will not be synced with FreeStyle Libre desktop software. The FreeStyle LibreLink app data is only stored by and visible through LibreView.
LibreLinkUp is a companion app to the FreeStyle LibreLink app, which allows glucose readings to be automatically shared with your caregivers in near real-time. Both you and your caregiver must have a network connection to share and receive glucose readings. To add a LibreLinkUp connection through the FreeStyle LibreLink app, simply tap Share in the main menu and follow the on-screen instructions.
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.
