• Be sure to select a site on the back of your upper arm that will minimise the risk of knock-off.
• Be careful not to catch your sensor on a doorway, car door, seat belt, or furniture edges.
• After a shower or swim, take extra care when toweling off to avoid catching or pulling off your sensor.
• When dressing or undressing, be careful that you don’t catch your undergarments on the sensor.

Understanding your glucose measurements

Why are FreeStyle Libre 2 sensor readings sometimes different from a fingerstick blood glucose test?
Blood glucose and sensor glucose are closely related but not identical. The glucose measured by the FreeStyle Libre 2 sensor has made its way from the blood into the interstitial fluid. This takes a little time and so the sensor glucose reading always lags behind the blood glucose reading of a fingerstick test by about 2.1 minutes for children and about 2.4 minutes for adults.1 When your glucose levels are stable, the two readings may be very similar. If glucose levels are rising or falling, the two readings may be different.
This is completely normal particularly after meals, after taking insulin or after exercising. Although the readings may differ slightly, the FreeStyle Libre 2 system is accurate1 and safe to dose insulin from your sensor glucose result.

Capturing your data

Real-time glucose readings are automatically updated every minute and sent directly to your smartphone1.

1. With the FreeStyle Libre 2 system, you get minute-to-minute glucose readings – anytime2, anywhere3 – to help you manage your diabetes more confidently.
2. Quickly see how diet, exercise, stress, insulin, medication and other activities affect your glucose levels, so you can take appropriate action.
3. You can also scan for glucose readings anytime’, even during a signal loss. This allows you to fill in up to 8 hours of missing data, so your glycemic picture is complete.

• The FreeStyle Libre 2 system enables the user to learn about how diet, exercise, insulin, and other activities
• The trend arrows show the direction that glucose is heading, supporting insulin management decisions.
• Optional glucose alarms4 let you know the minute your glucose is too low or too high.

Understanding your data

Reports that can easily and quickly provide the answers you need.

Time in Range

What is Time in Range?
HbA1c is your average glucose over the past two to three months. But a normal HbA1c doesn’t mean your glucose is within your target range today1, is where Time in Range can help.
Time in Range is the percentage of time that a person spends with their glucose your Healthcare Professional to set your target glucose range.
The FreeStyle Libre 2 system automatically calculates the percentage of time you spend in, above, or below target range, e.g. 3.9-10.0 mmol/L.

Why is Time in Range important?

• Every 10% increase in Time in Range results in ~0.8% decrease in HbA1 c in type 1 and type 2 patients2
• Every 5% (~1 hour per day) increase in Time in Range is associated with clinically significant benefits1
• Spending more Time in Range can reduce long-term eye and kidney health complications3
• Guidelines recommend spending at least 70% of your Time in Range (3.9-10 mmol/L)1,4

It’s easy to set alarms on your phone

The FreeStyle Libre 2 system has optional glucose alarms that provide a safety check every single minute. These are off by default and can be customised. To receive alarms your phone should be within 6 metres of you, and unobstructed at all times. If your phone is out of range of your sensor, you may not receive glucose alarms.

1. The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check the website for more information about device compatibility before using the app. Use of FreeStyle LibreLink may require registration with LibreView. 2. Signal Loss Alarm: Notifies you when your sensor has not communicated with the App for 20 minutes and you are not receiving Low or High Glucose Alarms. Signal loss could be caused by the sensor being too far away from your smartphone (over 6 metres (20 ft)) or another issue, such as an error or problem with your sensor. You must have override do not disturb settings enabled to receive alarms and alerts on your smartphone. 3. The Low Glucose Alarm setting can range between 3.3 mmol/L and 5.6 mmol/L. The Low Glucose Alarm can’t be set below 3.3 mmol/L. 4. The High Glucose Alarm setting can range between 6.7 mmol/L and 22.2 mmol/L.

FAQ

Why are FreeStyle Libre 2 sensor readings sometimes different from a fingerstick blood glucose test?

The sensor filament is positioned differently from capillary blood glucose tests, measuring glucose levels in interstitial fluid under the skin surface. This variance can lead to slight differences in readings. For more information, refer to the video explanation provided.
