A Portable Color Sensor Based Urine Analysis System to Detect Chronic Kidney Disease.

Chronic kidney disease (CKD) is a condition characterized by a loss of kidney function gradually over a period of time with five stages. Usually, in the initial stages, the disease appears to be asymptomatic as a result diagnosis of the disease in the early stages is unlikely. When diagnosed in the early stages (stages 1-2) the disease is completely reversible. For early diagnosis of the disease, we use a system consisting of sensor TCS3200 and a urine strip. The sensor detects the change in color on the strip when the sample is introduced. Change in color of the strip is due to the presence of albumin in urine, which is the primary biomarker considered to detect the early stage of kidney dysfunction.
