WHY Abbott FreeStyle Libre Continuous Glucose Monitor (CGM)

 The Abbott FreeStyle Libre is a type of Continuous Glucose Monitor (CGM) that allows users to continuously track their blood sugar levels. It lets you learn how your blood sugar responds to the food you consume and the activities you do, opening up opportunities for you or your care provider to identify ways to improve your blood sugar control. 

How do I apply the Freestyle Libre sensor

1. Choose a site on the back of your upper arm, where your triceps muscle is (this is where the product is licensed to be used). Clean the area with the alcohol wipe provided and allow to dry. 

2. Peel off the lid of the sensor and unscrew the cap from the applicator.

3. Place the applicator into the open sensor pack and line up the dark mark on the applicator with the dark mark on the sensor pack. 

4. Press the applicator down firmly until it comes to a stop.

5. Lift the applicator with the attached sensor out.

6. Holding the applicator in your hand, place it over the cleaned site on your arm. 

7. Push down firmly to apply the sensor.

8. Remove the applicator gently.

Can I remove the sensor myself?

Yes, you can.

The sensor lasts for up to 14 days, after which it will automatically stop glucose monitoring. At the end of the 14 days, the reader will no longer be able to read the sensor.

When the sensor has expired, you can easily remove it yourself. Lift the edges of the adhesive tape and slowly pull off the sensor to remove it. Some people find that removal in the shower using warm soapy water or using baby oil can help. Here is a video on how to remove and replace your sensor.

Other commonly asked questions regarding the use of the Abbott Freestyle Libre Sensor

Why do I have a gap in my data?

The sensor only holds 8 hours of data, so it is important to use the reader before going to sleep and when you wake up in the morning. You need to tap the sensor at least once every eight hours.  

How much data does the sensor hold?

The sensor stores glucose readings every 15 minutes, capturing that data in a rolling 8-hour log which can be downloaded with one scan of the sensor. You can also get an updated glucose reading every minute if you scan the sensor.

Can I bathe, shower, swim or exercise with the sensor on?

Yes. The sensor is water-resistant and you can use it while bathing, showering, swimming or exercising. However, the sensor should not be submerged in water deeper than 1 metre or kept underwater for longer than 30 minutes at a time. If you are swimming, the sensor will hold the data while swimming. After swimming, you should scan the sensor for information on your glucose levels. 

Please note that the reader is not waterproof and should not be used in the bath/shower or in the swimming pool. 

Can I change the time on my reader?

If you need to change the time, it is advisable to do this before starting a new sensor. It is not recommended to change the time on the reader after pairing as the stored readings will all be deleted. Therefore, it is not advisable to change the time zone even when travelling.

What should I do with my sensor at the airport? 

The glucose sensor and reader cannot go through the full-body scanners. However, they can be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors. You can safely use the system at all times in an aircraft. We can provide you with a letter for airport security purposes if required – please let the NOVI Health team know.

How do I interpret the data from my FSL Sensor?

The FSL provides you with rich data that can reveal opportunities for improvement to your blood sugar control.

We encourage you to have a discussion with your healthcare provider before you start monitoring so that you get the appropriate support and guidance throughout the process. You should also share your data with your health care provider to better understand your condition, and to get personalized advice on how to better manage your condition. 

Feel free to reach us to get your FSL data interpreted and explained to you too! Our pharmacist and nutritionists enjoy the process of optimizing someone’s daily habits and we would love to go through your data with you through an in-person or virtual consultation.
