Technology comes along in leaps and bounds, and every time you turn around it seems there's something improved, new, new-ish, getting-there and almost-but-not-quite-magical that has the potential to make living with diabetes easier. Unfortunately, it's become clear that there are some enterprising scammers out there who are producing and marketing products that sound just too good to be true, and at the moment they are. Take the mass of special watches, bracelets, and other gadgets being sold on Facebook and other platforms that claim to be able to measure blood glucose 'non-invasively' (see 2024 FDA article here). Recently we were sent an example of a $42.95 (down from $85.95) pulse oximeter that claims to give accurate blood glucose. We're sorry to confirm that this device and other examples aren't going to do what they claim, and by not doing what they say they will, have the potential to cause harm.
It isn't to say there isn't constant research going on by hard working people in reputable labs and research centers to achieve the holy grail of accurate diabetes monitoring without either finger pricking or wearing a CGM device, but for now, it's buyer beware when you find something on sale, particularly online. Thanks to Greg W for bringing this to the attention of the diabetes community, stay safe first and foremost, and anyone with any questions, make sure to talk to your health care provider.
