Some of them claim to extrapolate it from sweat, others claim to be able to estimate it from shining near-infrared at the blood vessels that are near the surface. Neither method has yet proven to be accurate, which is why they aren't certified as a medical device in UK. You can learn all about it by searching "non-invasive blood glucose monitoring" Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
