Apple Watch as a Glucose Sensor

They seem to be pushing their watch as a real time sensor for continuous glucose monitoring. Thats with nothing penetrating any skin. Anyone have a clue if this has any validity?

I've not heard anything about this but if I had to guess they're talking about it being able to monitor data from Continuous Glucose Monitors like Dexcom or something, just like a smart phone does since the watches are essentially just smaller smart phones anyway.

There's a claim that certain watches can non-invasively monitor blood glucose without needing anything like a CGM. It's bogus and doesn't work, the technology that can do that accurately enough doesn't exist in watch form currently.

Who is “they”? Apple? Apple has made no claims about the Apple Watch being able to act as a CGM. There are rumors that they’re working on that capability for future iterations, but the general consensus is that it’s multiple years out at best and would be a major breakthrough that would be widely reported if it were to be achieved

The watch does not have the ability to perform blood glucose tests. If someone is selling an app that says otherwise it’s a scam; currently it isn’t possible for the watch to check glucose levels. If you have a seperate CGM then there are apps that will show your glucose levels, but it’s the CGM that’s doing the testing, not the watch.

For years there have been rumors of Apple working on a watch that does have the ability to check glucose levels. If they were able to reliably report BG levels it would instantly become the favorite watch of diabetics and make Apple a metric ton of more money. The rumors I’ve heard, however, and that at first it most likely will report whether your glucose is steady, rising, or falling. That may be of interest to endurance athletes, but isn’t that inte

That is just tracking it in Apple Health, either through manually entering it or getting it from a third-party (dexcom, etc). There are a few other third-party apps that also will sync from your CGM to Apple Health too, none to it in real time though since its mostly limited by the APIs. Its not possible to track true BG without a sample of ..well.. blood.

It's a scam.

The current state of this technology is not available in watch form.

Did Apple make an announcement today? Last I check they are working towards that technology but it still off by a few years

And DME technology patterns are very strong which is why they had to go to court for the blood oxygen sensor and lose that fight

I’ve been getting adverts in my Facebook feed claiming that the latest gen watch can do glucose monitoring. Sounded way too outlandish to be credible but thought I’d check anyway.

I can confirm the latest one doesn’t

There is calls In the tech but it not here yet

With CGM there are app from our phone and Apple Watch that will give us reading I know Dexcom has it , not sure if Libre 3 has it yet

Libre 3 has a watch complication (I think that's what a watch app is called?). I think it came out with the latest update (version 1.2.0). It's nice to finally have it on my watch without using a kludge.
