The urine test strip method is widely used as a screening test since its results are a quick indicator of renal function. This method can be also used at home but results may vary due to personal error. The ultimate goal of our study was development of a simple and rapid semi-quantitative test system for urine component using a smartphone. It can be useful for early detection of symptoms of kidney diseases. In this study, we used a smartphone to take pictures of the urine test strip for albumin, with a color chart. GIMP was used to acquire the RGB value. The standard concentration of bovine serum albumin was diluted with distilled water to prepare 4 concentration samples. In this experiment, we showed the possibility of being able to assess the albumin level by comparing parameters of each color component extracted from the urine test strip and the color chart.
