  • Transmittance based system/kit for point-of-care quantification of biomarkers sample and use thereof
    Patent number: 10900909
    Abstract: A transmittance based system/kit for point-of-care quantification of biomarker samples includes a stage supporting a detection unit, an optical transmittance unit and a signal processing unit. The detection unit comprising reactive substrate is capable of undergoing a specific biomarker sample interactive reaction and generating a quantifiable optical signal proportional to the concentration of the said biomarker sample wherein the intensity of the color varies with the concentration of the analyte in the bio-sample. The optical transmittance unit, comprises a sample stage integrated with the light source and a photodetector, converting quantifiable optical signal transmitted through the reagent coated substrate detection unit to electrical signals, a signal processing unit connected to the said optical transmittance unit transduces the analogue electrical signal into the digital display signal.
