Recently, a new instrument for measuring blood glucose was created, using a laser sensor instead of pricking the finger, which will change the lives of millions of diabetic patients. In the past, diabetics monitored their blood glucose levels daily by pricking their fingers, squeezing blood drops onto test strips, and finally testing their blood glucose through a portable blood glucose meter. Because of the repeated testing of blood glucose over a long period of time, patients grew tired of this method of testing or became uncomfortable with it. Professor GinJose and his team from the University of Leeds, UK, have developed a new instrument that uses a small, low-energy laser to detect blood glucose by laser induction, replacing the traditional method of repeatedly pricking the finger. The new technique is simple and painless compared to traditional finger pricking. The results of the study show that the new instrument not only has the same test results as the traditional technology, but also can play its own advantages. However, more clinical trial studies are still needed to obtain regulatory approval before the new technology is released to the market.
