glucose testing

A newly-developed technology could end the need for finger-prick blood glucose testing.

The device, which has been developed by researchers from the University of Leeds, uses lasers to measure blood glucose levels without the need for skin penetration.

Most of the technology is not in itself new: with the exception of the type of glass used for the lens, it is largely made up of existing technologies.

The nano-engineered silica glass enables the lasers to create a fluorescence. The fluorescence can then be analysed in order to determine glucose levels of blood. The device can provide a constant reading of blood glucose levels.

“Unlike the traditional method, this new non-invasive technology can constantly monitor blood glucose levels,” said Professor Gin Jose, leader of the study.

“As well as being a replacement for finger-prick testing, this technology opens up the potential for people with diabetes to receive continuous readings, meaning they are instantly alerted when intervention is needed.

“This will allow people to self-regulate and minimise emergency hospital treatment.

Although the results of the study are hugely promising, the device is still at a preliminary stage in its development. Several further trials will be needed to determine the effectiveness and safety of the device.

That said, confidence is high. The designers are sure that the technology will one day be ready for the market, and in time could be developed into both portable and wearable forms.
