Know Labs has made progress with its work on creating a medical-grade non-invasive blood glucose monitor. Not only has the company built a Generation 1 prototype of the device that will use proprietary Bio-RFID sensing technology, it has also shared the promising results of a study that show how the machine learning model for the needle-free glucose monitor has performed.https://www.notebookcheck.net/Non-invasive-glucose-monitor-algorithm-from-Know-Labs-achieves-promising-overall-MARD-of-11-3-in-study-as-Gen-1-prototype-is-revealed.737562.0.html
For something non-invasive, this is already really accurate. I think many would want to use this over finger sticking despite a 10% variation from reference.
