Regular doctors' visits are essential for maintaining good health, but sometimes health issues can arise unexpectedly. In China, a company has introduced a unique concept of smart public toilets equipped with urinals that offer users a quick medical check-up for a fee. These urinals, as highlighted by documentary director Christian Peterson-Clausen, utilize built-in sensors and AI technology to analyze urine samples for various health markers like glucose, vitamin C, and white blood cells.

Peterson-Clausen shared his experience of using the urinalysis urinals in different parts of the city, emphasizing the convenience of receiving immediate health results. Despite concerns about privacy and accuracy, he appreciated the efficiency of the technology in providing quick health insights. These smart urinals, although not yet widely adopted, are currently available in select major Chinese cities such as Beijing and Shanghai.

While the technology offers a novel approach to health monitoring, there are limitations to its widespread use. Questions have been raised about the accuracy of results and the potential for cross-contamination due to the secretive nature of the testing methods. Additionally, the service is primarily tailored to male users, posing a challenge for inclusivity. Despite these drawbacks, Peterson-Clausen believes that such devices could serve as an initial health screening tool, prompting users to seek professional medical advice when necessary.
