Developed, Diabetes Checks Through Tears
Persons with diabetes should perform blood sugar checks more than 5 times a day because of blood sugar levels is changing. However, the current examination methods available only through blood sampling via syringe.
Because not all people are comfortable with a syringe, the scientists are trying to create an alternative blood sugar tests without pain. The latest is through an examination of the tear created by scientists from the University of Michigan, USA.
In experiments performed to rabbits, it is evident that the glucose is known of tears correlated with glucose levels in the blood. The researchers said the results of this research open up opportunities in the creation of an alternative blood sugar detection devices.
Prior has also been created glucose detection devices through the skin or ears. Jeffrey LaBelle from Arizona State University, along with researchers from the Mayo Clinic has also created a blood glucose monitor technology through tears.
With tools that monitor sensor is touched to the white part of the eye for five seconds to mengukurkadar glucose. according to LaBelle, measurement idea has been around since 1937. But the difficulty is to create a sensor that is sensitive to the sample fluid is very little.
"Glucose levels in tears usually 30-50 times lower than those in blood. In addition the volume of tear fluid is very little, "said LaBelle. Another disadvantage is if the eye is pressed outcome glucose readings can be inaccurate because he was responding to pressure.
Moreover, before this method is used should be equated first ratio between glucose in tears with those in the blood of each patient.
