Shedding Light on Accurate Non-Invasive Glucose Testing

by

scattered-lightThe way light scatters when transmitted through a  person with diabetes may be able to accurately determine glucose value. A study published in Iranian Journal of Medical Sciences shows that someday we may no longer have to endure bloodshed every time we check our blood sugar.

In this study, 900 people were evaluated using a non-invasive method of measuring peripheral blood glucose. Of the 900 people, 750 had diabetes.

This noninvasive method of reading HbA1c uses a laser beam. The laser beam was directed through a single tube to the index finger and the scattered beams were collected and measured for differences.

Although non-invasive blood glucose testing has been a hit or miss endeavor for decades, this method may be moving us in the right direction. Using a scientific approximation of these measurements, the researchers were able to correlate the scattered beams to HbA1c values.

Just how accurate were these non-invasive scattered beams when compared to clinical values of HbA1c? The data showed that outputs from the scattered beams were nearer to the clinical value. People with diabetes has significant differences in scattered light, compared to people without diabetes.

Light scattering is not new to science. In fact, it’s probably as old as the sun. However, when you apply a way of approximation to quantify blood glucose values, you’re giving new meaning to a guiding light .

    This is a gross misrepresentation of the actual article. They were measuring glucose, not A1c, and there were no predictive results, only a correlation study.You can download and read the article (or even the abstract) and learn that. Neither the study nor your reporting has any merit.
