A sensor has been developed by researchers at the University of Michigan that can detect glucose in a person's tears. A collaborative effort to advance this technology is being pursued by other researchers as well. Researchers at Mayo Clinic are attempting to create a sensor that you touch to the white part of your eye for five seconds for a glucose reading.
While poking the white part of your eye several times a day may not sound like an appealing alternative to pricking your finger, it would be less invasive and require no blood.
The main problem researchers are encountering in developing this technology is the low concentration of glucose in the tears as compared to blood. This means that scientists have to find the correct ratio of blood glucose to that typically found in the fluid of the eye to get a consistently accurate result. This would mean that each person with a tear glucose meter would have to calibrate their tear sensors on the meter to their blood glucose levels in order to get a correct reading.
The technology has a significant way to go before it would be available for purchase. Thus far it has only been used on animals.
If this technology were proven to be as accurate as blood glucose testing and was affordable, would you be willing to switch to this type of testing for your blood sugar? Post your comments below.
