Why it's important
In many regions of the world, it is difficult to get access to even basic healthcare incl. general and preventive examinations. The poorest are affected by this problem disproportionately.
One cheep and accessible way for these people to evaluate their health status could be urine strip tests. These tests comprise 10-20 different chemical pads that can measure different chemical components of urine providing the tester with insights about his/her health situation. Thereby the pads change their color that can be mapped to a particular measurement value of the considered chemical component.
While these tests are very suitable to help people in regions with bad access to healthcare get insights about their health status, they have two main drawbacks:
1. It is not always easy to map the resulting color of a chemical pad to the considered measured value
2. For non-medical persons, the results of the measurements are difficult to interpret
