Flash glucose monitoring is a new, 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.

You can use the built-in meter to check your blood ketone levels using  FreeStyle Optium b-ketone test strips. 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.

No. For convenience, there is a built-in FreeStyle Optium blood glucose and ketone meter within the reader that can be used for blood glucose and ketone readings.

The FreeStyle Libre flash glucose monitoring system is the first product in the flash glucose monitoring category and is designed to liberate people with diabetes from many of the hassles of glucose monitoring, such as routine finger pricking.

The FreeStyle Libre system contains two components:

FreeStyle Libre sensor: A small, disposable 14-day sensor that is worn on the back of the upper arm and automatically measures glucose levels and stores them for a period of 8 hours. Every time the user scans the reader over the sensor, the glucose data from sensor is transferred to the reader in 1 second.

FreeStyle Libre reader: A compact, handheld reader that displays glucose readings and stores up to 90 days of glucose data. When the reader is scanned over the sensor, it shows a current glucose reading, last 8-hours of data as well as a trend arrow (indicating if glucose is going up, down or staying steady). To obtain a glucose reading, simply perform a quick, 1-second scan of the reader over the sensor. This easy scan gives you more information than blood glucose monitoring without the need for routine finger pricks1.

 

1 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.

'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 healthcare professionals.

To obtain a glucose reading, simply perform a quick 1-second scan of the reader over the sensor.

This easy scan gives you more information than a blood glucose test without the need for routine finger pricks1. The FreeStyle Libre system also offers software to generate concise reports that provide a clear analysis of your glucose data.

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.

The FreeStyle Libre system is clinically proven to be accurate, stable and consistent over 14 days compared to blood glucose testing without the need for finger prick calibration

  • In a clinical study, the FreeStyle Libre system achieved 11.4% Mean Absolute Relative Difference (MARD) compared to blood glucose testing2
  • 99.7% of glucose results fall within Zone A and Zone B of the Consensus Error Gridwhen compared against blood glucose testing2
    • The measurement errors associated with these zones have no effect on clinical action and little or no effect on clinical outcomes3

Interstitial fluid-based glucose readings are a reliable indicator of blood glucose levels4

  • The physiological lag in ISF glucose, with respect to changes in blood glucose, is about 5-10 minutes4
  • The average lag time of the FreeStyle Libre system is approximately 5 minutes, which is unlikely to impact routine day-to-day treatment decisions3, 4

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 a new 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.

The FreeStyle Libre Flash Glucose Monitoring System is indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with diabetes mellitus. The indication for children (age 4 - 17) is limited to those who are supervised by a caregiver who is at least 18 years of age.

The caregiver is responsible for managing or assisting the child to manage the FreeStyle Libre Flash Glucose Monitoring System and also for interpreting or assisting the child to interpret FreeStyle Libre readings.

Both the reader and the sensor should be stored between 4°C and 25°C.

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. 

FreeStyle Libre sensors are programmed for sale in a specific market and are compatible with readers sold, compatible apps and software downloaded in that market:

  • FreeStyle Libre sensors in one market are not necessarily compatible with FreeStyle Libre readers or apps from other markets.
  • FreeStyle Libre users should plan on purchasing sufficient sensors from the same country they purchased their reader or downloaded their app from, to last the duration of their travel.
  • If planning a longer-term trip overseas, it is advisable to obtain a new reader or download a compatible app and software from that country, to be able to purchase and use the sensors available in that country.

 

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 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.

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.

'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.

The FreeStyle Libre Flash Glucose Monitoring System 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.

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.

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 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.

 

7The 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.

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.
