The problem is that the number you are getting is useless, there is no relative measure. Yes, maybe for you and for your particular fitbit recently, you may believe hat it 'works'. But you are very likely an outlier, there is no reason to believe some device like the glucose one will work for you or just about anyone else. The tech is essentially vaporware. Also, giving people even psuedo-medical diagnoses is just irresponsible; either it works or it does not. You can't tolerate psuedo-random number generators with health in any way. This is why 23andMe has to licence their genetic counselors on what the results mean, as the data can be very easily misunderstood by even very well educated people. Harvard just released a study on the fitbit, even the best of them were far off on something as simple as calorie counting: https://med.stanford.edu/news/all-news/2017/05/fitness-trackers-accurately-measure-heart-rate-but-not-calories-burned.html https://med.stanford.edu/news/all-news/2017/05/fitness-track...
