Although, many diagnostic tests today are still expensive and necessitate delicate procedure which can put the patient to harm or health risks, improvements on technology give rise to beneficial diagnostic equipments which are not only cost-effective, but also less invasive. Various diseases can now be rapidly and accurately diagnosed through the use of certain equipments which are found to be effective and efficient in determining and identifying whether a person is positive of a specific disease or not. In fact, determination of blood sugar levels can now be achieved using tear sample rather than blood, according to researchers.

Blood sugar levels are very significant parameters being examined by the doctors especially for patients who have metabolic and endocrine problems. Usually, examination of blood sugar level is done through a simple procedure called as Capillary Blood Glucose Testing (CBG). The procedure just necessitates a lancet, and equipment which will read the blood sugar level. However, some patients feel awkward and pain, thus, they hesitate to submit themselves for CBG because the procedure entails pricking of part of their distal finger in order to draw blood and be tested. And some of these patients, needed to be tested not only for one time, but for several times depending on the order of the doctor.

The new method of measuring the blood sugar level was reported in the Analytical Chemistry by the researchers from the University of Michigan. The researchers deemed to discovery a new method of measuring blood glucose through a pain-free procedure, and that is through the use of tear glucose levels.

During the animal studies, researchers found out that blood glucose levels can be accurately monitored through the use of tears from the rabbit using an electrochemical sensor device. In addition, the researchers wrote in the abstract: “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.”

Moreover, the findings of the research provided an extension of wide range of diagnostic tests which the general public can opt to choose. Also, according to the researchers, the new device was specifically helpful to have an accurate monitoring of blood glucose level leading to an effective glucose control, especially to those individuals who are hesitating to prick and draw blood just to test for their blood sugar levels.
