The rapid evolution of the continuous glucose monitor (CGM) has brought flexibility and convenience to diabetes control.
Continuous glucose monitors (CGMs) have transformed how many people with diabetes manage blood sugar, but attempts to monitor blood glucose have a long history.
Efforts to manage glucose kicked off in earnest when researchers began measuring glucose in urine in the mid-1800s. Scientists’ ability to do so steadily improved over the years, but urine glucose testing wasn’t commercialized until 1908, establishing a foundation for diabetes care.
Elkhart, Ind.–based Ames Company refined the process in 1945 with the introduction of Clinitest reagent tablets, which are still commercially available, albeit from Bayer. The company would introduce the first blood glucose test strip in 1965. The Dextrostix-branded strips were intended for use in doctors’ offices.
In the 1970s, Ames developed a device known as the Ames Reflectance Meter to m…
