Mobile Toilet Health Detection
The results of health detection using smart urinals in mobile toilets are for reference only, with questionable accuracy and should not be used as a basis for diagnosis.
Detection Principles and Methods:
Take health-monitoring urinals as an example. They employ dry chemical analysis, determining test results based on the final color of the test strip after urine reacts with it, and generating a comprehensive health index through algorithms. This detection method is essentially qualitative testing, meaning it can only determine whether certain indicators are present or their approximate ranges, rather than precise quantitative analysis.
Accuracy Controversies:
- Interference from Non-Human Body Fluids: The minimum reference values for a few parameters on dry chemical test strips are not zero. If non-human body fluids such as purified water or carbonated beverages are poured in, the system will default to displaying the closest detectable values. For example, testing with purified water may show abnormal results like 'high nitrite levels, low urinary calcium', which clearly do not match the actual situation.
- Inconsistent Results for the Same Sample: Some journalists have personally experienced that the test reports for the same urine sample are inconsistent, indicating poor detection stability and low result reliability.
Comparison with Other Market Products:
There are also smart toilets on the market with health detection functions, such as the Yunmi AI Health Detection Toilet Air. It automatically measures blood oxygen and heart rate through PPG sensors on both sides of the seat when a user sits down, providing detailed values within a few minutes. This detection method is based on bioelectrical signals, differing from dry chemical analysis, but it is also important to be aware of its scope of application and limitations.
Summary and Recommendations:
Although smart urinals in mobile toilets offer a convenient way for health monitoring, their detection accuracy is affected by various factors, and the results are for reference only. For an accurate assessment of health status, it is recommended to visit a regular medical institution for professional testing. Regarding new health monitoring devices like smart toilets, their functions should also be viewed rationally to avoid over-reliance on non-professional test results.
