Researchers at Hokkaido University working with private-sector scientists have developed a device to measure the blood sugar level of diabetic patients via the use of an electronic beam, according to informed sources.

Doctors have already started clinical tests on the system, which does not involve drawing blood, at Seiwa Memorial Hospital in Sapporo.

Patients with serious cases of diabetes who require insulin treatment are required to measure their blood sugar level two to four times a day through blood samples.

"If diabetics can measure their blood sugar level without taking blood, it would substantially improve their quality of life," said Mamoru Tamura, professor of bio-spectroscopy at the university's Research Institute for Electronic Science and the principal developer of the device.
