FreeStyle Libre 3 Plus 15 Day Sensor: A Game Changer

Introduction

FreeStyle Libre 3 Plus 15 Day Sensor is Abbott’s latest continuous glucose monitor (CGM) with a factory-calibrated, 15-day wear time, streaming glucose readings every minute to a compatible smartphone via the Libre app after a 60-minute warm-up. It’s FDA-cleared, ultra-small (same as that of Libre 3, which has been the smallest CGM sensor in the world), and designed with ease and accuracy for people with diabetes. While that is just an overview, let’s dive deep to have a deep dive into why the FreeStyle Libre 3 15-Day Sensor is a Game Changer – Libre 3 Plus to be exact.

7 Major Advantages of Libre 3 Plus Sensors

Here’s what sets it apart from other CGMs available in the U.S.:

• 15-day Lifespan

An FDA-approved CGM sensor with extended wear time of up to 15 days—just two sensors per month—surpasses prior 14-day versions.

• Reduces A1C

Studies suggest Freestyle Libre 3 Plus sensors reduce A1C. How can you lower A1C fast? Read this expert’s guide.

• Quick Warm-up Time

Just a 60-minute warm-up before live data begins, shorter than some older systems, e.g., Libre 2 sensors.

• AID Compatible

Freestyle Libre 3 Plus sensors are smart, both in terms of size and specs. These AID (automatic insulin delivery) system compatible sensors can be integrated with some latest automatic insulin pumps, e.g., iLet Bionic Pancreas – a smart AID system for type 1 diabetics.

• Water Resistance

Suitable for swimming or bathing, the Libre 3 Plus is water-resistant for up to 1 meter (3 feet) of water for a maximum of 30 minutes.

• Eligibility—Age & Diabetes Type

– Libre 3 Plus: FDA-indicated for children 2 years and older
– Approved for Type 1, Type 2, and gestational diabetes.

• Glycemic Variability tracking and trend arrows

Minute-by-minute data via the app supports trend analysis and time-in-range tracking. With easy color trends, i.e.,

• Orange for high glucose (above 250mg/dL)
• Yellow for going low or high
• Green for within target range (customizable)
• Red for low glucose (below 70mg/dL)

Just a glance at your Freestyle Libre 3 Plus application can inform you of your glucose levels.

Important: Freestyleserver suggests storing the sensor kit in a dry and cool place. A sensor kit stored below or above the recommended temperature, which is between 36°F and 82°F, may cause inaccurate results.

Caution: If readings do not match symptoms, use a blood glucose meter.

Conclusion

Suitable for type 1, type 2, and gestational diabetes, this FDA-approved Freestyle Libre 3 Plus Sensor is not just a continuous glucose monitor; instead, a smart way to manage diabetes. Its small size (same as Libre 3 sensor), longer wear time (15 days), AID compatibility, and impact on A1C make it stand out from the crowd. On top, with their minute-to-minute glucose readings combined with hyperglycemia and hypoglycemia alerts, these sensors help diabetics make informed decisions and reduce hypo or hyperglycemia events.
