Researchers develop non-invasive blood sugar test

24th March 2014

Researchers have come one step closer to developing a practicable, non-invasive blood sugar test for patients with diabetes.

Treating the metabolic disorder requires routine glucose monitoring, which is usually carried out with a finger-prick test – something many people find painful and inconvenient.

However, a new report published in the International Journal of Biomedical Engineering and Technology this month argues that spectroscopy could be used as a substitute.

Researchers from RWTH Aachen University, Delft University of Technology and the Indian Institute of Technology in Delhi observed the impedance of spectral lines in a blood sample test depend on the concentration of glucose.

Using data from reference tests with standard solution, they were able to accurately deduce blood sugar levels with electrodes placed on patients' forearms.

They warned, however, that several other factors could affect impedance in such a test, among them skin type and skin moisture.

The researchers are now examining these issues in order to develop further prototypes.ADNFCR-8000103-ID-801705853-ADNFCR
