Libre 2 Plus (CGM) compared to blood glucose monitoring (BGM)
BGM only gives you a snapshot of your blood glucose, at a single point in time. Glucose monitoring with Libre 2 Plus provides a more complete picture of trends and patterns without finger prickings.10,17
How does the sensor reading compare with a blood glucose reading?
Traditional Blood Glucose Monitoring
Measures the glucose levels in the blood (capillary).
A lancet is inserted to reach the blood in the capillary.
A finger prick only provides one measurement at one point in time.
The Libre 2 Plus system
Continuously measures the glucose levels in the interstitial fluid (ISF): the fluid between the cells under the skin.
Glucose readings based on interstitial fluid have been shown to reliably reflect glucose levels.80
The sensor records glucose reading every minute, even when you're sleeping.
Why does this matter?
Glucose first enters the bloodstream before being absorbed by the interstitial fluid.70
This means there may be a few minutes delay in sensor (interstitial fluid) glucose readings compared with blood glucose readings. This is called "the lag".70
Let’s use a train to demonstrate “the lag”
Imagine glucose levels as the train tracks
Sensor glucose
Blood glucose
Sensor glucose follows behind blood glucose. Let's see what happens when glucose levels change.
When glucose levels remain stable, the glucose levels recorded by the Libre 2 Plus sensor and blood glucose are similar, though not always exactly the same.
With rapidly rising glucose levels, the Libre 2 Plus sensor reading may be lower than the blood glucose levels.
For rapidly falling glucose, the Libre 2 Plus sensor reading may be higher than the blood glucose levels.
The difference between blood glucose and sensor glucose readings is greater, following a rapid change in glucose levels after eating, after insulin, and after exercise.
Libre 2 Plus gives you a more complete picture of your glucose:
Continuous glucose monitoring (CGM) with Libre 2 Plus provides insight into how lifestyle choices impact glucose levels.17,204
Patients do not test as often as they should because of the pain and hassle of finger pricks206,223 and many do not achieve optimal glycemic control.223, 224, 225

Please read and understand the following information related to the use of the FreeStyle Libre Flash Glucose Monitoring System and consult your healthcare provider for any clarifications or queries related to your treatment of diabetes:
Indication for use:
The FreeStyle Libre Flash Glucose Monitoring System is indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with diabetes mellitus. The indication for children (age 4 - 17) is limited to those who are supervised by a caregiver who is at least 18 years of age.
It is designed to replace blood glucose testing in the self-management of diabetes with the exceptions listed below. Under the following circumstances, use a blood glucose meter to check the current glucose readings from the FreeStyle Libre Flash Glucose Monitoring System Sensor.
Conditions when a blood glucose test with finger prick is required:
During times of rapidly changing glucose levels, interstitial glucose levels as measured by the sensor and reported as current may not accurately reflect blood glucose levels. When glucose levels are falling rapidly, glucose readings from the Sensor may be higher than blood glucose levels. Conversely when glucose levels are rising rapidly, glucose readings from the sensor may be lower than blood glucose levels.
In order to confirm hypoglycemia or impending hypoglycemia as reported by the sensor.
If symptoms do not match the FreeStyle Libre Flash Glucose Monitoring System reading. Do not ignore symptoms that may be due to low blood glucose or high blood glucose.
