The device claims to have 97% of reading within 15% of the Freestyle Libre, which itself is then not as accurate as blood glucose. Put another way, it’s less accurate than a device that’s already less accurate than finger sticks. Given this info, I’m not sure this version is practically useful yet in terms of accuracy.

Patients averse to finger sticks are going to use this much more often. It's going to provide more useful data to them. Much of the time the exact number isn't as important as knowing the trend or the general range.

Whether this makes more sense than a Libre for someone just depends on price and how insurance treats it.

I tested my blood sugar when my wife was pregnant and she was testing hers. I was amazed at how just from the small blood stick, and even if I had my wife do it and didn’t see any blood, I’d get sick to my stomach every time I did a blood stick. I’m glad I don’t have diabetes or I’d have a terrible time of it.

The Dexcom G6 is the best CGM on the market, but its sensor filtering (Kalman or particle?) has smoothness and/or continuity priors that cause persistent inaccuracies.

Is there a good source for info on ketogenic diets for type 1 diabetics?

“We know that not all people with diabetes are looking for a wearable continuous glucose monitoring device to manage their diabetes." Okay that's pretty bogus. Some people can't afford it, but everyone with diabetes would benefit from a CGM. There's much more to be gained from trends in CGM data than singular data points. (I was diagnosed with Type 1 at 16, been on a CGM for most of that time).

> 16x daily finger stick blood testing

Is that typical for people with your condition? Once an hour while you are awake? I never knew people had to do it that often.

A completely non-invasive device even getting close to the accuracy of finger stick or implanted devices is a big deal.

Agreed, as a diabetic and climber I've used a lot of the libre pucks but honestly, there is no spot on my body I wont use while practicing my sport. Still the libre was miles better than always pricking my fingers and arms.

I've been thinking about what kind of EM-signal could be used for this for a long time, IR-spectroscopy never seemed possible. But this has real potential.

I do what works best. Typical is not my concern.

A glucometer test takes 20 seconds, total.

I would say it is quite high, I've never been recommended to measure that much even

I can't say enough good things about my G6. It literally changed my life as far as how I interact with my diabetes.

- I feel safer when I go to bed, because it's there to wake me up if my blood gets low (or too high).

- I feel safer in general because I don't need to worry that my blood is low but I haven't noticed it; and that I'm going to just fall down face first while walking across the room.

- Testing my blood is just a matter of looking, vs going over to (or downstairs to) where the tester is.

- (Because of the above) I have a better "feel" for how my blood sugar reacts to various foods and activities.

- When I'm having trouble with my sugars (morning highs, for example), I can see what my history has been via nice graphs on their web site.

Honestly, it's amazing. While I respect your choices, I can only assume you weren't taking full advantage of just how wonderful having the G6 is.

I worked on the Freestyle Libre, I’m thrilled to hear it’s at least a workable solution for you. When I was working at Abbott, I often volunteered for testing finger-stick devices, which made me appreciate a small part of what people with diabetes have to endure.

Keto is generally best once you've finished developing. If she's under 18, I wouldn't do Keto.

She's right on the bubble, but something tells me I've got some time.
