Noninvasive Blood Glucose Monitoring with Optical Coherence Tomography

Abstract

In recent years, continuous glucose monitoring (CGM), a noninvasive and accurate measurement of blood sugar, has been developed. Although the traditional finger-prick method is accurate, it is not suitable for multiple daily use because it is very painful and the test strips are expensive. Although minimally invasive and noninvasive CGM systems have been introduced, they are quite expensive and require blood to be drawn from a fingertip. Given the prevalence of diabetes in low- and middle-income countries, there is an urgent need for accessible, noninvasive blood glucose monitoring devices. This article briefly reviews noninvasive blood glucose monitoring technology and related research. The communication media are optical, transdermal and enzymatic. This present study evaluates the system in an experimental form for blood glucose measurement are discussed. The review concludes with key points and insights for the future development of diabetes testing.
