Intended Use

LibreLinkUp is intended for use by caregivers to assist people with diabetes in the review, analysis and evaluation of historical glucose meter data to support effective diabetes management.

In addition:

LibreView is a secondary viewer and is not intended to provide treatment decisions or to be used as a substitute for professional healthcare advice.

LibreLinkUp is not intended to be used by clinicians.

Patients should not rely on caregivers to notify them about low or high glucose.

Dosing decisions should not be made based on this device. The user should follow instructions on the continuous glucose monitoring system.

Any problems with the mobile device, NFC, Bluetooth, wireless internet connection, mobile data connection, FreeStyle LibreLink, LibreLinkUp or LibreView could cause data to not be shared with caregivers, or delay transmission to caregivers.

LibreLinkUp should be used only to give a secondary level of awareness and should not be expected to always communicate and transfer sensor glucose information.

LibreView is intended for use by patients, caregivers and healthcare professionals to assist people with diabetes and their healthcare professionals in the review, analysis and evaluation of historical glucose device data to support effective diabetes management.

In addition:

LibreView is a secondary viewer and is not intended to provide treatment decisions or to be used as a substitute for professional healthcare advice.

LibreView is not intended to be used for immediate clinical decision making, and is not intended to replace self-monitoring practices as advised by a physician.

How FreeStyle Libre apps and LibreLinkUp work with LibreView

For FreeStyle Libre app users that choose to share their glucose data with a LibreLinkUp user:

  1. Glucose readings are uploaded from FreeStyle Libre Sensor to a FreeStyle Libre app.

  2. The FreeStyle Libre app transmits the glucose readings to the LibreView cloud for storage using WiFi or a cellular data plan.

  3. A family member or friend can install the LibreLinkUp app on their own phone and accept the sharing invitation. The FreeStyle Libre app user is now a Connection in the LibreLinkUp app.

  4. The family member or friend can view the Connection’s glucose readings in the LibreLinkUp app.

Getting Started With LibreLinkUp

Sharing data from a person wearing a FreeStyle Libre Sensor with a family or friend involves two apps:

FreeStyle Libre apps
The person wearing the FreeStyle Libre Sensor uses a FreeStyle Libre app on their mobile phone to send a sharing invitation email to their family member or friend.
LibreLinkUp
The family member or friend receives the invitation email and follows the instructions to install the LibreLinkUp app on their own mobile phone.

After the sharing invitation is accepted, the family member or friend will receive glucose data and glucose notifications through LibreLinkUp.

Below are instructions for each app:

Understanding Glucose Readings

For LibreLinkUp App Versions 4.0 or Later

When you open LibreLinkUp, you will see the latest glucose reading from your connections, an arrow indicating which direction their glucose is trending, and a glucose graph.

1

Navigation Menu

Tap to open the navigation menu.

2

Notification Settings

Tap to go to the connection’s notification settings.

3

Glucose reading card

The bold number indicates your connection’s latest glucose reading in what’s called a glucose reading card. The color band on the reading card indicates whether your connection’s glucose is high, low, in target, or out of target.

  1. Red indicates a low glucose reading(<70 mg/dL or 3.9 mmol/L).

  2. Orange indicates a high glucose reading (>250 mg/dL or 13.3 mmol/L) for FreeStyle Libre 3 users, (>240 mg/dL or 13.3 mmol/L) for all other users.

  3. Green indicates readings in your connection’s target range.

  4. Yellow indicates readings between your connection’s target range and their high and low thresholds.

In some cases, instead of a bold number, you may see a glucose reading of “LO” or “HI.”

  1. "LO" indicates a glucose reading lower than 2.2 mmol/L (40 mg/dL).”

  2. "HI" indicates a glucose reading higher than 22.2 mmol/L (400 mg/dL) for United States and Canada FreeStyle Libre 2, 27.8mmol/L (500 mg/dL) for all other users

If either of these readings is seen, the App User Manual that corresponds to the FreeStyle Libre app states that the user should check their blood glucose with a test strip. If they get a “LO” or “HI”result from a blood glucose meter, the FreeStyle Libre app user should contact their healthcare professional immediately.

In other cases, instead of a bold number and timestamp, you may see --- and “No Recent Data”. This appears because no data from your connection has been received in the LibreLinkUp app in the last 5 minutes.

You may see --- and “No Recent Data” for the following reasons:

  1. If your connection is using a FreeStyle Libre sensor:

    • Your connection has not scanned their sensor in the last 5 minutes

    • Your connection does not have an active FreeStyle Libre sensor

    • There is a service interruption that is preventing the uploading of glucose data from the FreeStyle Libre app to LibreView services

  2. If your connection is using a FreeStyle Libre 2 sensor:

    • Your connection has not scanned their sensor in the last 5 minutes

    • Your connection does not have an active FreeStyle Libre 2 sensor

    • Your connection is experiencing signal loss with their FreeStyle Libre 2 sensor

    • There is a service interruption that is preventing the uploading of glucose data from the FreeStyle Libre app to LibreView services

  3. If your connection is using a FreeStyle Libre 3 sensor:

    • Either your device or your connection’s device has no Internet connectivity

    • Your connection does not have an active FreeStyle Libre 3 sensor

    • Your connection is experiencing signal loss with their FreeStyle Libre 3 sensor

    • There is a service interruption that is preventing the uploading of glucose data from the FreeStyle Libre app to LibreView services

4

Trend arrow

This arrow shows which way your connection’s glucose was heading at the time of the scan. There are five possible trends:

Glucose is rising quickly

More than 0.1 mmol/L (2 mg/dL) per minute

Glucose is rising

Between 0.06 mmol/L – 0.1 mmol/L (1‐2 mg/dL) per minute

Glucose is changing slowly

Less than 0.06 mmol/L (1 mg/dL) per minute

Glucose is falling

Between0.06 mmol/L – 0.1 mmol/L (1‐2 mg/dL) per minute

Glucose is falling quickly

More than 0.1 mmol/L (2 mg/dL) per minute

5

Glucose graph

The glucose graph displays up to the last 12 hours of your connection’s available glucose history, high and low glucose alarm thresholds (if the connection is using a FreeStyle Libre sensor that supports glucose alarms and the glucose alarm setting is enabled in the LibreLinkUp app), and the connection’s target glucose range.

The glucose graph is interactive: tap anywhere in the glucose graph area and the glucose reading card will be updated with the glucose value and timestamp for that point on the glucose trace. The glucose graph is updated each time the app is opened to the glucose graph screen if your device has internet connectivity. Gaps may appear in the glucose trace if this glucose data is not available in the connection’s glucose history. If the connection’s glucose reading exceeds 21 mmol/L (350 mg/dL), the glucose trace will display at 21 mmol/L (350 mg/dL) but the glucose reading card will accurately display the connection’s glucose reading for that time.

For the high and low glucose alarm thresholds on the glucose graph:

  1. If your connection is using a FreeStyle Libre 2 sensor:

    • The high and low glucose alarm thresholds will appear at the alarm threshold glucose value set by your connection in their FreeStyle Libre app.

  2. If your connection is using a FreeStyle Libre 3 sensor:

    • The high and low glucose alarm thresholds will appear at the alarm threshold glucose value set by you in the LibreLinkUp app.

The target glucose range is the green shaded area in the glucose graph, and the values are set by the connection in their FreeStyle Libre app.

6

Logbook

Tap to go to the Logbook screen.

The logbook displays the last 2 weeks of glucose events.

  1. If your connection is using a FreeStyle Libre sensor:

    • The glucose events include glucose readings when the connection scanned their sensor.

  2. If your connection is using a FreeStyle Libre 2 sensor:

    • The glucose events include glucose readings when the connection scanned their sensor and shared glucose alarms.

  3. If your connection is using a FreeStyle Libre 3 sensor:

    • The glucose events include customized glucose alarms you received based on your connection’s glucose readings.

Tap on a glucose event in the list to view event details.
