Measurement of Specific Gravity, Urobilinogen, Blood, Protein and pH Level of Urine Samples Using Raspberry Pi based Portable Urine Test Strip Analyzer

Urinalysis has been a helpful tool in detecting some common diseases. It has been used to diagnose conditions such as urinary tract infections, kidney disorders, liver problems, and other metabolic conditions. Regular urinalysis may be done to detect early signs of diseases and prevent it, but it is also time consuming and costly. Urine has several components and some of the parameters can be examined through the use of a urine test strip analysis. This paper presents a portable raspberry-pi based system that is designed to analyze the key parameters of urine namely, specific gravity, urobilinogen, blood, protein, and pH level. This study is focused in determining the key parameters of urine samples aforementioned which are essential in diagnosing early signs of disorders. Image processing was used in order to properly identify the positioning of each pad in the strip and to obtain the color change evaluated in terms of HSV color space analysis. Statistical analysis was performed in order to compare the values measured by the urine test strip analyzer to the actual laboratory urinalysis test. Using T-test, the results show that there is no significant difference between the values measured by the urine test strip analyzer and the actual laboratory urinalysis.
