Researchers show effectiveness of new noninvasive blood glucose test

ScienceDaily | 10/10/2018 | Staff
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 160 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.

"Currently, blood glucose levels are tested through a finger prick or intravenously. The approach we studied is noninvasive and uses a laser to monitor glucose levels in the skin," said Anandhi Upendran, PhD, director of biomedical innovations at the MU School of Medicine Institute for Clinical and Translational Science and co-author of the study. "With diabetes on the rise, the development of an accurate, efficient and inexpensive alternative method to test blood glucose levels is an urgent clinical need."

Developed by researchers from MIT, the device uses a technique called Raman spectroscopy to measure the chemical composition of skin and extract the amount of glucose out of other skin compartments. A fiberoptic cable attached to...
