It’s finally here. The Dexcom G7 has landed. And now it’s time for us here at Diabettech to pitch it against Abbott’s Freestyle Libre 3.
Both these devices have been circulating for some time, amid mounting excitement amongst a reasonable portion of the diabetes community, as published data suggests a better user experience.
We’ll be undertaking the usual diabettech treatment to compare both these new devices with their older, and incumbent, siblings, to see which proves to be the most effective.
What we’re testing…
Dexcom’s G6 and G7
Abbot’s Libre 3
All theee devices will be run against each other using the same methodology as used for the previous comparisons, described here.
Headline Statistics
Here, we are using the G7, appropriated from Ireland, which uses the updated algorithm, as used in the Accuracy study, and with a published headline MARD of 8.7% in Adults.
The Libre3 supposedly has a MARD of 7.9%.
Over the next 10 days or so we’ll see how those numbers reflect with my use, and how they compare to the G6.
All data is collected using the official apps.
As always, the caveats apply regarding n=1 and individual experiences, however, it will be good to see whether my experience reflects the anecdotes about sensor inaccuracies and jumpy data that are circulating on social media.
Stay tuned for further updates!
