2.5. UC-3500

UC-3500 interprets the test strip through a CMOS sensor, measuring the light reflected from the reagent strip pad [6]. A decrease in reflected light corresponds to a higher analyte quantity. The protein pad contains 0.015 mg of tetrabromophenol blue, while the albumin pad contains 0.01 mg of tetrabromophenol blue. Both detect urine protein (measurement range: 15–1000 mg/dL) and albumin (measurement range: 10–150 mg/L) using the protein error of the pH indicator method. The creatinine pad contains 0.48 mg of 3,5-dinitrobenzoic acid and generates a garnet-red color in the presence of creatinine (measurement range: 10–300 mg/dL).
