Non-invasive and rapid diagnosis of type 2 diabetes mellitus based on the analysis of hair by front-face fluorescence spectroscopy
Diabetes is a global health problem and one of the leading causes of death in the world. Blood glucose testing is needed for early detection and blood glucose control, both of them being key in increasing the quality of life of those affected with this disease. Currently, blood glucose control is done by doing a finger-prick test, which is uncomfortable, inconvenient and can lead to infection. The authors of this article propose a non-invasive blood glucose test by measuring the fluorescence of hair. This technique uses a single LED and a spectrometer and is completely non-invasive and comfortable for the patient. The results showed good discrimination between healthy and diseased patients, and also between patients who have good control over their blood glucose concentrations and those who do not. These results are a step forward in the development of a device that would be useful in the early diagnosis of diabetes and also a more convenient and non-invasive method for blood glucose control.
