Sysmex Corporation (HQ: Kobe, Japan; president: Hisashi Ietsugu) and Toshiba Corporation (HQ: Tokyo; president: Tadashi Okamura) today announced the joint development of technology for micro-invasive self-measurement of blood sugar levels. This technology newly developed by combining Sysmex’s micro-invasive tissue fluid extraction technology with Toshiba’s optical sensing technology allows glucose levels to be measured using interstitial fluids instead of the blood samples currently required by conventional techniques. Eliminating the need to puncture a fingertip to obtain a blood sample will contribute to improved quality of life for diabetes patients. Development of the technology for practical use is currently underway from this year, aiming at commercialization in 2005.

So-called “lifestyle-related diseases” -- that is, those caused by poor dietary habits, insufficient exercise, excessive stress and other aspects of modern life -- have been increasing annually. Among these, the number of people suffering from diabetes worldwide had climbed to approximately 170 million as of 2000, with projections suggesting further increases to as many as 370 million by 2030. The market associated with the blood glucose testing currently amounts to approximately ¥400 billion, or about 16% of the overall diagnostics market, and average annual growth of 10% or more is expected in the years ahead.

Diabetes is a disease typically showing few subjective symptoms, but if left untreated it can easily lead to any or all of three major types of complications, including neurological disorders, retinopathy (affecting the retinas of the eyes), and nephropathy (causing reduced kidney function). In treating diabetes, it is necessary to control the level of blood glucose in order to prevent the occurrence and/or progression of these conditions. Among the ways to control blood glucose, some of the most important include dietary treatment, physical exercise, and medicines, but to ensure the effectiveness of these approaches it is important to monitor blood glucose levels regularly and constantly.

Diabetes patients typically measure their own blood glucose levels by pricking a finger to obtain a droplet-sized sample of blood. The pain and discomfort caused by repeating this procedure several times a day provided the incentive for undertaking the development of a device to monitor blood glucose levels less invasively.

The minimal-invasive blood glucose self-measurement technology developed jointly by Sysmex and Toshiba measures the amount of glucose in interstitial fluids rather than in blood samples, resulting in a method that improves the quality of life by avoiding the need for painful blood sampling. Sysmex handled development of technology for painless and stable extraction of interstitial fluid samples, while Toshiba was responsible for developing the biosensor chips and detection unit hardware for precisely measuring the minute amounts of glucose contained in the samples.
Development of the technology for practical use is currently underway from this year, aiming at commercialization in 2005.
