Modern Express News (reporter Xie Xizhuowen / Photo) Going to the toilet, can you do a urine test by the way? Recently, in the men’s washroom of Wuyue Plaza on Hubei Road, Nanjing, a citizen found a urinal for health testing. The above shows that in just three simple steps, urine can be tested on the spot. So, are the test results of this new type of urinal reliable? Will personal privacy be leaked? On May 27, a reporter from Modern Express found “urine calcium” in pure water after using the urinal to measure it.

[Actual measurement] Purified water can also detect “urine calcium”< /p>
In appearance, this urinal is larger than ordinary urinals, with a honeycomb-shaped urine sample port in the middle and a display screen on the top. “Three simple steps, fast and accurate.” Around the screen, there are also diagrams of the steps used: urine sampling, scan code payment, and view reports. In addition, there is a small red text next to the display: “This product is not a medical device, and the results cannot be used as a basis for diagnosis, but only as a reference for health management data!”

In the process of using this urinal, the top display screen will automatically switch pages: a “utility model patent certificate” is displayed on the left, It occupies nearly one-third of the entire screen, and the certificate is stamped with the seal of national intellectual property rights. In the middle of the screen is a QR code for scanning and payment, and on the far right are 10 items of “2021 urine test abnormal rate distribution”: “urine calcium 37.89%, glucose 24.30%, microalbumin 21.19%, protein 19.64%, ascorbic acid 15.51% …”
△Scan the QR code in the middle of the display to pay
Around 10 am on the 27th, the reporter first used the Take a urine sample, follow the on-screen prompts, open WeChat, scan the QR code on the display, and enter a small program called “Encounter Test”, and finally successfully pay 19 yuan. About two minutes later, a test report popped up on the WeChat applet of the mobile phone, which marked 14 data results including white blood cells, urobilinogen, microalbumin, protein, bilirubin, and ascorbic acid. Among them, 9 items are displayed as “negative”, and the remaining 5 items are displayed as specific values.

△Pure water test report
In order to verify the reliability of the test results, the reporter opened a new bottle of pure water and tested it in another urinal next to it. Unexpectedly, this bottle of water was also tested with relevant data, and the test data was the same as the last urine test. In particular, the 5 items of data showing values such as “microalbumin”, “specific gravity”, “creatinine”, “PH value” and “urine calcium”, the data of the corresponding options before and after the two tests are exactly the same.
[response]The measured value is the interval value of the sample data
Is it as some people worry that using this kind of equipment is paying IQ tax?
At noon on the 27th, a reporter from Modern Express called the customer service number on the urinal: 400-6488698. “Our test data is relatively standard, and it is the same as the principle of buying test strips online.” On the phone, Manager Zhang of Beijing Shaoduo Technology Co., Ltd. said that the equipment adopts “dry chemical analysis method”, which is used by many hospitals. method. “This is a qualitative test, not a quantitative test. It is equivalent to identifying the color of electronic components to assign urine files.”
“There are 14 color blocks in the device, each color block Represents a value, when the urine in the sampling area is drenched in the color block, there will be a change in the corresponding color, and then the corresponding data will be displayed.” Manager Zhang told the reporter of Modern Express that whether it is pure water or urine, the machine can detect it. The character of the sample is obtained, and then the machine judges the interval value of the sample data through the change of the color of the color block. “For example, there are 5 interval options for white blood cells, and at least 1 of them must be selected during machine detection.”
△ Health Check Urinal p>
Among the 14 items of test data, the last item “urinary calcium” has five options: 1.0, 2.5, 5.0, 7.5, 10, etc. In the two test reports obtained by the reporter, this indicator is ” 2.5mmol/L”, and the following prompt text: “Urine calcium is high for a long time, and the urinary system may be at risk of stones or kidney calcification…” Is there also “urine calcium” in pure water? In this regard, Manager Zhang first said that “there are many affected environments”, and later said, “I don’t know how to answer you…”
The urinal for health testing is recycled, so, How can we ensure the accuracy of the data for each test? Manager Zhang said that due to the infrared sensor on the device, when someone comes to urinate, the system will sense it. After the test result comes out and the relevant person leaves, the system will automatically flush the urinal and sampling area to ensure that the next person When the user tests, there is no residual urine of others in the urine sampling area.
Some people questioned whether such a new type of smart urinal would leak personal privacy. Manager Zhang told the reporter of Modern Express that the entire device, except for an infrared sensor light, does not have the camera that everyone is worried about. , and the urine test report obtained by the system is also anonymous, and there is no problem of revealing the privacy of others. “Users pay by scanning QR code on WeChat, no real-name authentication is required, and each time the system gets a test report, the corresponding user only hasA string of numbers, but we cannot know who this string of numbers is. “
[Suggestion] is for reference only, please choose a professional hospital for urine test
Is a urinal such as a health test reliable? With questions, a reporter from Modern Express interviewed Jiangsu Province Traditional Chinese and Western Medicine Zhang Wen, the chief physician of the Nephrology Department of the Joint Hospital, said that this kind of self-test equipment and the test strips prepared by many people, the so-called results in two minutes, can only reflect the general problem of the tester’s body, at most one Health reminders cannot accurately judge the condition. He suggested that if citizens really need a urine test, they must go to a professional hospital.
Zhang Wen said that there are many types of urine tests, and the general ones are simple Routine urine test, further quantitative analysis of urine sediment, etc. Usually, patients can do a census first, and they can get the general test results quickly. If problems are found in any aspect, quantitative analysis can be carried out in a targeted manner.” For example , If the urine routine finds glucose positive, the possibility of diabetes should be considered. If the white blood cells are positive, there is the possibility of urinary tract infection. If the urine protein is positive, further urine protein quantification is required. “
“The test data of urinals similar to this kind of health test must still have certain errors compared with the test of professional hospitals. Zhang Wen said that “dry chemical analysis” is a rapid detection method, but there are many factors that affect it, so there are big differences. Now many hospitals use high-precision biochemical equipment for testing. Patients are tested in the hospital. In the urine test, in addition to the rigid requirements of each individual sampling and testing, the doctor will specifically instruct the patient to take the morning urine, and when sampling the urine, the middle part of the urine should be selected to ensure the accuracy of the test.
Why does purified water have the same test data as urine? Zhang Wen said that water does have a certain “PH value”, but “microalbumin”, “specific gravity”, “creatinine” and “urine” were detected in it. Calcium” and other data, “According to the existing results, this test is obviously inaccurate. ”
