Freestyle Libre 3 Sensor

The FreeStyle Libre 3 System is only compatible with certain mobile devices and operating systems. If you use Android or iOS operating systems, you should have no problems connecting the sensor to your phone, but it currently doesn't support Windows smartphones.

If you're unsure of device compatibility, please check the website for more information.

No, the best thing about this system is that it ensures that you don't need to perform a finger prick test every time you want to measure your levels.

Instead, you'll apply the sensor with an applicator and connect it to your smartphone. You'll then receive minute-by-minute updates that will help you identify whether you have high or low glucose levels.

Yes, you can wear the sensor when you shower, exercise, or swim. However, it shouldn't be exposed to water for longer than half an hour.

No, please don't use the sensor if you want to check your blood sugar and don't have diabetes. It won't provide accurate results and is only designed for diabetes management.

The sensor will automatically send readings to your phone using Bluetooth technology. However, if you accidentally turn your Bluetooth off, the sensor won't be able to send this information.

Yes, but you only need to do this when you apply a new sensor. Once you scan it, the sensor kit will need 60 minutes to warm up; it will automatically send glucose readings to the app.

While all FreeStyle Libre systems, including the FreeStyle Libre 2, are highly accurate, this system has demonstrated more accuracy than previous kits. As long as you follow the instructions on the sensor kit packages and apply the kit correctly, it will send instant updates.

Your sensor sends glucose values from interstitial fluid, which is generally accurate. However, it lags behind your glucose levels by a few minutes. So, when your body experiences rapid changes in glucose, it can compromise your readings.

Taking high amounts of Vitamin C can also affect sensor readings, which means you won't be able to assess glucose trends properly. Understanding these risks can help you avoid errors in insulin dosages.

Yes, you can use the LibreLinkUp app to share your data with up to 20 people – including family members, friends, and your diabetes healthcare professional. This allows others to track your glucose history and identify any potential issues.

While the FreeStyle Libre 3 system is generally considered safe, like any medical device, it can have potential side effects. It's important to be aware of these and to consult with your healthcare provider if you experience any significant issues.

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.

Yes. People with diabetes can use FreeStyle Libre sensors with the FreeStyle LibreLink or FreeStyle Libre 3 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 apps with FreeStyle Libre sensors, including insulin dosing decisions, based on guidance from their healthcare professional.

The FreeStyle Libre systems are indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with diabetes mellitus. The indication for children (age 4 – 12) is limited to those who are supervised by a caregiver who is at least 18 years of age. A caregiver at least 18 years old is responsible for supervising, managing, and assisting the child in using the FreeStyle Libre system and interpreting its readings.

The FreeStyle Libre systems have been studied in two landmark randomised controlled trials (RCTs) which demonstrated improvements in diabetes outcomes for both Type 1 and Type 2 patients with diabetes, those are:

Bolinder J,et al. Novel glucose-sensing technology and hypoglycaemia in type 1 diabetes a multicentre, non-masked, randomized controlled trial. The Lancet 2016.

Haak T, Hanaire H, Aijan R et al. Flash glucose-sensing technology as a replacement for blood glucose monitoring for the management of insulin-treated type 2 diabetes: a multicentre, open-label radomised controlled trial. Diabetes Ther. 2016.

The FreeStyle Libre systems have not been evaluated for use by persons on dialysis.

If you are using the FreeStyle LibreLink or FreeStyle Libre 3 mobile app to monitor your glucose levels, you can invite your family/caregiver to access your glucose data remotely, anytime by using LibreLinkUp app. Visit the LibreLinkUp page to see how to do this.

The FreeStyle Libre systems are only indicated for humans.

You are encouraged to share your data with your healthcare professional so that they can better work with you to manage your daily routine. Through LibreView, you can automatically share your data with your healthcare professional by linking your LibreView account to their Healthcare Practice. Alternatively, you can email yourself or print a PDF of your reports to share with your healthcare team.

No. With the FreeStyle Libre 3 System, you do not need to scan to receive a glucose reading. When your FreeStyle Libre 3 Sensor is paired with your smartphone, you will automatically see the latest glucose information after you open the FreeStyle Libre 3 app or when you receive an alarm notification on your compatible smartphone.

Finger pricks are required if your glucose readings and alarms do not match symptoms or expectations.

There's no need to use a separate blood glucose meter for routine testing. The FreeStyle LibreLink and FreeStyle Libre 3 apps allow you to get glucose results as often as you like. If you're using the FreeStyle Libre 2 system, simply scan your FreeStyle Libre 2 sensor with your phone to get a glucose reading. If you're using the FreeStyle Libre 3 system, glucose readings will be streamed to your phone every minute.

When starting a new sensor, users must choose which device they would like to use and if they want to share glucose data with their caregiver or healthcare provider.

The FreeStyle Libre 3 Sensor can be used with the FreeStyle Libre 3 app.

Yes, the FreeStyle Libre 3 system works with LibreLinkUp. Family and friends who are connected to FreeStyle Libre 3 app users via the LibreLinkUp app will receive continuous glucose information automatically on their smartphone every single minute. LibreLinkUp app users can also customise their glucose alarm settings to receive glucose alarms at their preferred level.

The FreeStyle Libre 3 system is not yet available on prescription. It will be available via the NHS Supply Chain Insulin Pumps, Continuous Glucose Monitoring, Closed Loop Insulin Delivery Systems and Associated Products framework. People with Type 1 diabetes can check the eligibility criteria for real-time CGM on the Diabetes UK or JDRF websites. The FreeStyle Libre 3 system is intended for people with Type 1 diabetes with more complex management needs, who require a real-time CGM.

The FreeStyle Libre 3 Sensor measures glucose every minute and updates glucose values in the app every minute. Historic glucose readings (shown on the 12-hour glucose graph) are stored in the app every 5 minutes.

The FreeStyle Libre 3 System is a continuous glucose monitoring system that sends glucose readings every minute directly to your smartphone1 so you can act faster to avoid hypoglycaemia. It has the same unsurpassed 14-day accuracy as the FreeStyle Libre 2 System. Being the world’s smallest and thinnest most discreet , glucose sensor (about the size of two stacked 5 cent Euro coins or two stacked U.S. pennies), FreeStyle Libre 3 users can view their glucose levels discreetly and conveniently.

Our FreeStyle Libre Digital Ecosystem provides you with the FreeStyle LibreLink mobile phone app, FreeStyle Libre 3 app and LibreView. LibreView is a secure cloud-based software that allows both you and your doctor to connect remotely at no cost.
