The clinical diagnosis based on biofluid composition in blood plasma is an essential method for detecting pathology. Biofluid in the blood plasma of organism contains an interstitial fluid such as glucose is percursor the source energy in the synthesis process. Blood glucose metabolism is fluctuating and has a biomarker normality threshold. This research to confirm the performance of IR-LED wavelength 1450 nm and 1600 nm and exclude biochemical reagent processes, blood sampling, infection, and medical waste. Continuous measurement of glucose disease can improve quality of life and reduce the risk of systemic diseases. The transmittance method with an incident wavelength certain has maximum penetration depth in the body tissue. The mechanism of transmittance includes incident light in blood glucose with specific wavelengths and a photodiode detected. Transmittance is voltage, then converted to analog values into digital readings. The research has conducted in the Laboratory of Physics Material Electronic-IPB University. Sample preparation used cuvette with the design system modular modified based on reference and pearson correlation for data analysis. The scatter diagram shows the results of the IR-LED 1600 nm has good performance and can be a light source device in non-invasive biomarkers.
