Researchers from the University of Missouri School of Medicine and the Massachusetts Institute of Technology recently evaluated the accuracy of an MIT-developed technology to monitor blood glucose levels without needles smartwatch diabetes a finger prick. Early results show that the noninvasive technology measures blood glucose levels as effectively as a finger prick test—without drawing blood. The study, "Evaluation of accuracy dependence of Raman spectroscopic models on the ratio of calibration and validation points for non-invasive glucose sensing," measured the blood glucose levels of 20 healthy, non-diabetic adults prior to drinking a glucose-rich beverage.
Blood glucose levels were then measured in intervals over the next minutes using three methods: spectroscopy, IV blood test, and finger prick. The tests are designed to determine how much glucose remains in the blood and if a patient's insulin-regulating mechanisms are working effectively. The researchers found that spectroscopy predicted glucose values as accurately as a finger prick test.
Applying FreeStyle Libre 3... It finally happened!
The approach we studied is noninvasive and uses a laser to monitor glucose levels in the skin," said Anandhi Upendran, Ph. A fiber optic cable attached to a smartwatch diabetes passes laser light onto the skin to detect different components in the skin, such as fat tissue, protein, collagen and glucose molecules. The shifts in wavelengths associated with glucose present in the blood create a sort of molecular fingerprint that can be used to determine glucose levels.
The gold standard is intravenous smartwatch diabetes testing, but frequent blood draws may not be an option for many patients.
We were pleased to find that our initial results show Raman spectroscopy can measure glucose levels that are comparable to the finger stick devices.
You can get it by following the update notification on your Huawei Health App, then enabling the new feature there. If you aren't familiar with SpO2, you're hardly alone, and we'll fill you in! Longer explanation: "S" refers to saturation, "P" pulse, "O2" oxygen - hence "SpO2", which indicates the smartwatch diabetes of oxygen-carrying red blood cells within the total red cell count in your blood. In practical terms, SpO2 tells you how well your respiratory and circulatory systems are working.
We hope that we can refine this method to be a noninvasive continuous glucose monitoring sensor. Future studies will examine the accuracy of the technology in patients with diabetes.
