What purpose do this machine serve?

Both The Libre 3 and Dexcom G7 are continuous glucose monitoring (CGM) systems designed to assist patients with diabetes in controlling blood glucose levels.
Below is a clear comparison of the two systems, explaining their differences and features in more depth:
Each System’s General Description
Libre 3:
Distributor: Abbott.
Working: The user evaluates the amount of glucose in the interstitial space under the epidermis by approaching the sensor and scanning it with a reader or smartphone for glucose results.
Length Of Sensor Wear: Maximum duration of up to 14 days.
Dexcom G7:
Distributor: Dexcom.
Working: It measures glucose under the skin and provides alerts. Unlike the G6, the G7 can provide Additional Alerts and send messages directly to your smartphone or other compatible devices.
Length Of Sensor Wear: Maximum duration of up to 10 days.
The Differences In Point Form
The Differences In Sensor Insertion And Design
Libre 3:
More compact and discreet sensor design.
Users are required to scan their glucose level with a reader or app.
Dexcom G7:
Although slightly bulkier than the Libre 3, they are still easier to insert.
It eliminates the need for a scan and pairs it with a device for automatic data transfer.
Displays Data And Alerts
Libre 3:
A sensor should be used to receive glucose readings.
Real-time alerts for data highs and lows are available only when scanning is performed.
The glucose monitoring device sends signals and alarms to notify the user of abnormally high and low glucose levels, using real-time data transmission.
Calibration
Libre 3:
The user requires no calibration as the sensors are factory-calibrated.
Dexcom G7:
Optional headings may be permitted for precise and accurate readings. However, most models are calibrated automatically when the monitor is turned on.
Other Devices Integration
Libre 3:
Primarily a stand-alone device that can be used with some insulin delivery systems.
It can be used with the LibreLink app on mobile phones.
Dexcom G7:
It pairs better with other forms of diabetes management apps and insulin pumps.
The information is also available on multiple devices, enabling the patient and their nurses or relatives to check the levels remotely.
Cost and Accessibility
Libre 3:
It is more cost-effective than other glucose monitoring systems like Dexcom G7.
The coverage relies on the plan as well as the provider.
Dexcom G7:
Due to the rich features, new technology, and 24-hour monitoring, the device is expensive compared to its rivals.
In some cases, the insurance available may require further approval, and coverage is not uniform from provider to provider in most cases.
The current technology level in the market shows a surge of CGM systems, such as the Libre 3 and Dexcom G7, which help patients monitor their glucose levels. The Libre 3 has the advantages of sensor scanning and a longer scanner life. In contrast, the Dexcom G7 only has a sensor and receiver with phone settings such as transmission or alerts. Choosing one of the two occurs with matching lifestyle requirements on how diabetes is best managed.
