I just read an interesting article on diabetescare.net concerning testing blood glucose levels by using TEARS rather than blood. The article is based on a report published in the American Chemical Society journal Analytical Chemistry. An abstract of the report and the full report can be read at pubs.acs.org.
The following is from the diabetescare.net article-
“Scientists are reporting development and successful laboratory testing of an electrochemical sensor device that has the potential to measure blood sugar levels from tears instead of blood… “
"Thus, it may be possible to measure tear glucose levels multiple times per day to monitor blood glucose changes without the potential pain from the repeated invasive blood drawing method," say the researchers.
The following is from the ACS abstract-
“The glucose sensor was employed to measure tear glucose levels in anesthetized rabbits over an 8 h period while also measuring the blood glucose values. A strong correlation between tear and blood glucose levels was found, suggesting that measurement of tear glucose is a potential noninvasive substitute for blood glucose measurements, and the new sensor configuration could aid in conducting further research in this direction.”
It may not be tomorrow when we need not test from blood but there is a light at the end of the tunnel. I know my poor fingers are cheering. In fact I thought I heard a few hallelujahs and amens. How do your fingers feel about this alternate type of testing?
