A new study published in Nature examined the potential of noninvasive blood glucose monitoring devices on 50 people with type 2 diabetes over two days. Raman Spectroscopy used an 830nm near-infrared light on the thumbs for 50 seconds to analyze the reflected light. The results were then compared to traditional blood tests for accuracy, and the study introduced a pre-trained calibration model to improve reliability.
It was based on a previous study with 160 participants and improved the calibration process. Now the calibration requires four hours for 10 measurements instead of taking too much time and once the device is calibrated, it remains accurate for at least 15 days. These results show that this method can be reliable for tracking blood glucose in people with type 2 diabetes.
Even though the study didn't use any specific devices, the Raman spectroscopy technique is the same one as Apple’s future blood glucose tracking Apple watch. Apple has been working on blood glucose monitoring watches since 2017 but there are still some challenges in ensuring that it gives reliable results while being a wearable device. For now, the closest thing to Apple's blood glucose tracking watch is Dexcom G7 which has a patch-based blood glucose monitor. Samsung is also working on non-invasive blood glucose monitoring using AI.
