The Freestyle Libre 2 Reader by Abbott

The freestyle Libre 2 reader is a continuous glucose monitor (CGM) that tracks your blood sugar levels without needing finger pricks. It uses a sensor inserted under the skin and reads the glucose in your interstitial fluid.

It can also be used to upload data to your doctor for review. A finger prick blood sugar test is still required to confirm low or high readings and diagnose hypoglycemia.

Easy-to-use interface

The Freestyle Libre 2 Reader is designed to provide a painless and non-invasive way to monitor glucose. It does this by scanning the sensor patch with the reader device, allowing you to see a real-time glucose reading and trend graph. It can also provide you with historical insight into your glucose trends. This allows you to make more informed decisions regarding treatment adjustments or lifestyle changes.

The device offers a simple user interface, making it easy to navigate for users of all ages and technological backgrounds. You can view your current glucose level and a historical glucose trend with just one swipe. You can even set optional swipe-free alarms to notify you of high or low levels.

Unlike traditional CGM, the Freestyle Libre 2 reader does not send continuous data to the smartphone or tablet. Instead, a scan of the sensor with the reader will obtain the glucose data and trends, and the user can then review these on their mobile device. This eliminates the need for fingerstick calibrations and allows individuals to choose their own glycemic goals without constantly checking their blood sugar.

The device has several other helpful features, including the ability to set up two different profiles for use with the same sensor. It can store up to 200 sensor reads, displaying the readings in an easy-to-read format. The device can also transmit the data from a paired sensor to other devices, such as a smartwatch or computer.

Instantly track glucose trends.

Abbott’s Freestyle Libre 2 Reader is FDA-approved for kids as young as 4 and adults with type 1 or type 2 diabetes. It stores up to 90 days of glucose history and has a number of reports that can help you analyze trends and patterns in your blood sugars.

It also has a unique feature called Trend Arrow, which shows the direction and rate of change in your current readings. This can help you anticipate whether your blood sugar rises, falls, or stays steady. This can help you avoid high or low blood sugars and make informed food choices and activity choices.

Another great thing about the Libre system is that you don’t need to calibrate it with a fingerstick meter check as with some CGM systems. You just need to swipe the sensor with the reader and get a reading. It’s a good idea to double-check with a finger prick test to verify the reading, though.

Another benefit of the LibreLinkUp app is that it lets caregivers or loved ones conveniently see your glucose levels. This can be helpful if you have a busy lifestyle and don’t have time to check the sensors as often as you should. However, the app does need to be enabled, and a few other permissions must be granted for this to work.

Easy-to-read LCD screen

The Freestyle Libre 2 Reader by Abbott has a large LCD screen that shows the current glucose reading, the last 8 hours of history, and a trend arrow. The monitor also has a button to call customer service for support and can be used with the FreeStyle LibreLink app* to receive notifications on your smartphone.

The device uses near-field communication, or NFC, to transmit data from the sensor to the receiver. This works just like some credit cards, which can be read by tapping them on a card terminal. Each transmission takes about a minute and gives you a full picture of your glucose levels.

This monitor only works with FreeStyle Libre 2 sensors. If you have a different sensor brand, it will not work with the reader or the FreeStyle LibreLink app*. Glucose alarms will only be received on the device you used to start the sensor (reader or smartphone).

Battery life

The Freestyle Libre 2 Sensor Kit by Abbott is an innovative system that helps individuals manage their diabetes with continuous glucose monitoring (CGM). The device comprises a small, discreet sensor and a reader that users wear under their skin for 14 days. The device uses a small amount of interstitial fluid to monitor blood sugar levels and then estimates blood glucose using an algorithm. It also enables people to avoid the need for finger prick testing, as it provides real-time results and is water resistant.

The wireless system works with an app downloaded to a smartphone or dedicated reader that uploads data to a cloud-based diabetes management system. Users can also access reports and settings using the free LibreLink or LibreView desktop software. However, the software requires a Windows or Mac computer and may not run on older devices.

In February, Abbott issued a voluntary medical device correction for its FreeStyle Libre and FreeStyle Libre 14-day flash glucose monitoring systems due to the risk of overheating or fire. The problem is associated with the lithium-ion batteries in the reader, which can swell or overheat if not properly stored, charged, or used. The company is recalling 4,210,785 readers sold between November 2017 and February 2023. Fortunately, no one has been injured or killed in incidents related to the problem.
