Clinical trials with a non-invasive and painless system, which can assess people's average blood-sugar levels, is all set to begin in Christchurch, New Zealand.

Scientists at Canterbury University have joined forces with medical researchers at Christchurch Hospital for the purpose.

The researchers believe that the breakthrough system may revolutionise the way diabetics' long-term glucose levels are monitored, and provide an easier way to identify people with the disease.

They say that the machine can provide diabetics with an accurate snapshot of their blood-sugar levels, based on which they can adjust their food, exercise, and medication without the need for painful blood tests.

Dr Brett Shand, a member of the Lipid and Diabetes Research Group at Christchurch Hospital, said that trials could take around two.

The researcher revealed that the machine would detect glucose levels accurately by the fluorscence of skin under ultra-violet light.

According to Shand, all the test would involve was having a fluorescent light shone on patients' skin.

"The measurement takes two to three minutes. It's non- invasive, painless and the UV-exposure is harmless," stuff.co.nz quote Shand as saying.

The researcher further said that the new test would be cheaper than laboratory blood tests, and could be used for screening.

"It could help us identify patients who could have diabetes and require blood tests to confirm the diagnosis. Early detection is so important because if we get on top of the disease at an early stage it reduces the risk of complications," Shand said.
