Because we've had a lot of tech that promised non-invasive glucose monitoring, and so far it just hasn't panned out. Don't get your hopes up.
There's a difference between "can detect that the value is double or more the norm" and "can detect fluctuations of 30%". Diabetics tend to need the latter.
But that's exactly my point: assuming this rumor is true at all, I wouldn't be surprised if the sensor can't quite reach that level of accuracy. It can tell you if your value is about 80 or about 160 (or beyond), but not if it's in between. That's IMO just not good enough for doctors to sign off on it, because it can mean a difference of multiple insulin units.
Now, my expectation here could be wrong. Perhaps Apple has found a way to make the measurements just as accurate as invasive ones. That doesn't strike me as likely, though.
Is everything in the report information that the source actually
has, or (much more likely) is a limited amount of information embellished and padded out with wishful thinking? There are a lot of questions unanswered, such as:
- precision? (e.g., 100 mg/dL? 50? 20?)
- does it need to be calibrated?
- there's a mention of Samsung shipping similar tech — is Apple licensing Samsung's tech? Is Samsung licensing Apple's tech? Are both licensing something from a third party? Did both just happen to have this breakthrough the same year? None of those seem very likely.
Sure.
Other options like Dexcom do exist, though.
Naturally, a less accurate measurement is better than none at all. If the end result is that people measure once or twice a day with an invasive method, and
on top of that use the Watch for quick rough measurements, fair enough.
