What it is
FreeStyle Libra 3 is a small sensor from Abbot that measures your glucose all day and night. It is about the size of two small coins stacked on top of each other: 21 mm across, under 3 mm high and 1 gram in weight.
How it works
You use the applicator to press the sensor onto the back of your upper arm. It is ready to use 60 minutes after you put it on. From then on it measures the glucose in the fluid just under your skin and sends a new value every minute to the FreeStyle Libre 3 app or the Libra 3 reader. You see your current number, an arrow that shows where it is heading, and a graph of your day.
The sensor keeps 14 days of data, one value every five minutes. If your phone is out of range for a while, the missing values fill in when it comes back. You can turn on alarms for high and low glucose, and one for when the signal drops. With the LibreLinkUp app, people you invite can see your readings too. You can shower and swim with it, down to 1 metre for 30 minutes.
Who it’s for
Libra 3 suits you if you want live readings on your phone from a very small sensor. You need a compatible smartphone or the Libra 3 reader. Your diabetes team can help you choose between Libra 3 and Libra 3 Plus.
Questions
Can I switch between the app and the reader?
No. The FreeStyle Libre 3 app and the Libra 3 reader don't share data. Once you start a sensor with the reader, you can't use it with the app, so choose one before you begin.
Do I have to scan the sensor?
No. Libra 3 sends a reading every minute by itself while your phone or reader is close enough.
How is it different from Libra 3 Plus?
Both use the same small sensor and the same app. Libra 3 lasts up to 14 days. Libra 3 Plus lasts up to 15 days and is approved for more age groups and more insulin pump systems.
Can I shower or swim with it?
Yes. It is fine in water down to 1 metre for up to 30 minutes.
