Blood Glucose Monitoring

The most important development in the commercialization of urine glucose testing

1908

Stanley Rossiter Benedict developed a copper reagent for urine glucose, which was used, with some modifications, for more than 50 years.

The first glucose meter

Period: 1970 to 1979

The first glucose meter was used in the 1970s, but the precision and accuracy of the meter was poor.

Improvement of SMBG

Period: 1985 to 2000

Through the late 1980s, 1990s, and early 2000s, Self-monitoring of blood glucose technology continued to improve. Smaller amounts of blood were required, electrochemical strips were developed, and new enzymatic tests were used.

Guardian Real-Time CGM

2004

In 2004, Medtronic introduced the Guardian REAL-Time CGM system, which could notify users of potentially dangerous hyperglycemia or hypoglycemia.

The FreeStyle Navigator

2008

In 2008, the FreeStyle Navigator by Abbott was released in the United States.

G4 Platinum

2012

In 2012, Dexcom introduced the G4 Platinum.

FreeStyle Libre Pro

2016

In 2016, Abbott introduced the FreeStyle Libre Pro. This CGM is unique in that the sensor can be worn for 14 days.

The Guardian Sensor 3

2017

In 2017, Medtronic’s first hybrid closed-loop device, the Guardian Sensor 3, was available.

Conclusion

2022

CGMs have revolutionized the way diabetes is managed and measured. As for the future of CGMs, scientists are testing new and better kinds of CGM systems in trials.
