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. The simple, single step, cost-effective easily disposable system/kit is useful for point-of-care detection of important biomarkers such as amylase, creatinine, albumin, among others.
