New, non-invasive blood sugar testing methods using saliva

Recommended Posts

Still Waters

Despite breakthrough diabetes research over the past century, people with diabetes still need to rely on obtaining blood samples to monitor their sugar levels. Daily glucose monitoring by tracking blood sugar levels is essential for managing both types 1 and 2 diabetes, however the current method—finger pricking—is invasive and can become burdensome with how often it needs to be done.

Since 2014, flash glucose monitoring was first introduced in Europe and this method uses a small, water-resistant sensor applied to the back of the upper arm. Compared with finger pricking monitor, this approach is more convenient but these sensors have known accuracy issues and some could fail altogether.

In the quest to eliminate invasive glucose monitoring for people with diabetes, research led by Wenyu Gao, a Ph.D. student in the Department of Chemistry at the University of Waterloo, explores using saliva instead of blood to monitor glucose levels.
