How to Use the FreeStyle Libre 2 System for Continuous Glucose Monitoring
If you have diabetes, you know how important it is to monitor your glucose levels regularly. But fingersticks can be painful, inconvenient, and costly. That’s why many people are switching to continuous glucose monitoring (CGM) systems, such as the FreeStyle Libre 2 system.
The FreeStyle Libre 2 system is a CGM system that allows you to check your glucose levels anytime, anywhere, without fingersticks. It consists of a small, discreet sensor that you wear on the back of your upper arm and a smartphone app that you use to scan the sensor and view your glucose data.
In this blog post, we will show you how to set up and use your FreeStyle Libre 2 system, and how it can help you manage your diabetes better.
Step 1: Download the FreeStyle Libre 2 App
The FreeStyle Libre 2 app is the companion app for the FreeStyle Libre 2 system. It allows you to scan your sensor with your smartphone, view your current glucose level, trend arrow, and history graph, customize your glucose alarms, share your data with your healthcare team, and more.
To use the FreeStyle Libre 2 app, you must register with LibreView, a cloud-based diabetes management system that securely stores your glucose data and allows you to access it online.
You can download the FreeStyle Libre 2 app from the App Store or Google Play Store for free. Make sure your smartphone is compatible with the app by checking the compatibility guide.
Step 2: Apply Your Sensor
The sensor is part of the FreeStyle Libre 2 system that measures your glucose levels every minute and stores up to 8 hours of data. It is easy to apply 1,2 with a simple one-step process.
To apply your sensor, follow these steps:
Wash your hands and clean the application site on the back of your upper arm with an alcohol wipe. Let it dry completely.
Open the sensor pack by peeling off the lid. Do not touch the inside of the lid or the adhesive.
Unscrew the cap from the sensor applicator and set it aside.
Place the sensor applicator over the sensor pack and press down firmly until it clicks into place.
Lift the sensor applicator from the sensor pack. The sensor is now attached to the applicator.
Place the sensor applicator on the back of your upper arm and push down firmly until you hear a click. The sensor is now applied to your skin.
Gently pull off the sensor applicator and dispose of it safely. The sensor should stay on your arm for up to 14 days.

How To Customize Your Glucose Alarms
One of the features of the FreeStyle Libre 2 system is the optional, real-time glucose alarms that alert you when your glucose level is too high or too low. The alarms will even trigger at night, so you can sleep better knowing that you are covered around the clock.
You can customize your glucose alarms to suit your preferences and needs. You can choose:
The glucose level at which you want to be alerted for high or low glucose
The sound and vibration pattern for each alarm
The snooze time for each alarm
The days and times when you want the alarms to be active or silent

Open the FreeStyle Libre 2 app on your smartphone and tap “Settings“.
Tap “Glucose Alarms” and toggle the switch to turn them on or off.
Tap “High Glucose Alarm” or “Low Glucose Alarm” to adjust the glucose level, sound, vibration, and snooze time for each alarm.
