Recently, some public restrooms in shopping malls have added physical examination items. With a scan of the QR code costing 19.9 yuan, 14 routine urine tests can be completed... Is it reliable that the last restroom visit can achieve the results of a physical examination? Faced with people's doubts, the company providing this service stated that the test results are only used as a reference for health management data. In the men's restroom of the Cuiwei store in Beijing Impression City, the words "health testing urinal" are particularly prominent on the electronic screen above a urinal, and the interpretation of "simple three steps, fast and accurate" is also particularly tempting. According to the instructions in the diagram, as long as you keep urine sampling and scan the code for payment, you can obtain a test report. The diagram also indicates that the device is not a medical device and the results cannot be used as a diagnostic basis, only as a reference for health management data. When someone approaches the electronic display screen, operation instructions will appear on the display screen. During the toileting process, the device will automatically collect samples and a payment QR code will appear. Users need to scan the code and pay 19.9 yuan to obtain the report. After scanning the code for payment according to the operating instructions, the mobile interface will automatically jump to the mini program of the product. After 2 minutes, you can receive a test report, which includes 14 indicators such as white blood cells, urobilinogen, bilirubin, ketone bodies, creatinine, and occult blood. Slightly different from the urine routine report issued by a tertiary hospital, the report only shows negative or positive results and does not display specific values. I took the test while browsing the mall, which is much cheaper than going to the hospital and physical examination center. If the results are accurate and the hospital approves, it's quite convenient, "said Mr. Zhang, who happened to be using the restroom. During the reporter's interview, it was found that most people were curious about this detection method, and occasionally some people would take out their phones to scan the code for fresh images. At the same time, many people also question this detection method, how is the inside of the detector disinfected? How to ensure that urine does not mix? Are the test results accurate? In addition, the reporter also found that this machine often fails to analyze payment and receive refunds due to weak signals and other reasons. At that time, the customer service didn't say where there was a problem or how to solve it, only said to try another one. Mr. Zhang, who was curious, made a try, but the result was unsuccessful. We are doing this project because the number of people participating in health checks in our country is increasing year by year, but a considerable number of people have awareness of health checks but do not have the time for health checks. The reporter contacted the institution that provides this service, and a staff member explained that the device detects users through infrared sensing and then uses urine test strips for testing. The test paper has 14 color blocks, each representing a numerical value. The machine will judge the health of the tester based on the color changes of the color blocks. It's just a routine urine test. Currently, we have launched it in high-speed service areas, scenic spots, and shopping malls. A total of 10 shopping malls have been launched in Beijing, and according to the operation results, many citizens have participated in the test, "the staff said. Passing the test strip can only serve as a preliminary screening, "said Zhan Yuliang, a technician at the Laboratory Department of Sino Japanese Friendship Hospital. The hospital's urine routine examination includes multiple contents, and in addition to using test strips, it also needs to rely on instruments for testing. Using only test strips for inspection, the results obtained are similar to
