I agree with @Mark Rawlinson 'Blood Vitals' is a blood oxygen monitor.
As yet no manufacturer has developed a non invasive glucose monitor. If and when they do, such a device would be advertised with a great deal fanfare and we would all most definitely know about it.
I’ve seen this advertised, I don’t really know how they can get away with it saying that is a blood sugar meter when it’s obviously not. Isn’t there such a thing as a trade description act or maybe I’m too old?
