Be wary of physiological urine test false positive Spring Festival is approaching, is still for their year-end physical examination report in the one or two + sign nagging, sleepless nights? Xiao A, a 25-year-old female, single, senior white-collar worker. Recently, the company organized a physical examination, just for the company’s year-end conference late into the night A followed the good sisters to the hospital physical examination center, after a series of laboratory tests, blood, chest X-ray, abdominal ultrasound and other items, she dragged her tired body home to catch up on sleep. Time flies in the busy, 2 weeks after Xiao A received the medical report, the medical knowledge of the extreme blank she saw the urine test items on the protein on a large +, immediately go online to search for a variety of knowledge, she is the more to see the more alarmed, “nephritis”, “uremia” these The more she reads, the more alarmed she becomes, “nephritis”, “uremia”, these horrible diseases come to her mind, she is still so young, she has not yet enjoyed her life, she has a “serious disease”? For the next week she was in a daze, always making mistakes at work, and when pressed by her boss, she finally couldn’t bear the pressure and told the truth. The boss was very reasonable and suggested her to see a doctor after 1 day of rest, so she sat in my office with a serious face. The results were also very satisfying to her, all negative. She couldn’t believe it and asked to be hospitalized. I could only listen to her silently as she finished her fear of UTI, and after she calmed down a bit, I explained to her a serious misconception in her daily life. With the increase of people’s health awareness, people take physical examination as a habit, but the human body is a constantly changing biological environment, people’s habits have a great impact on the metabolic substances in the human body, for example, strenuous exercise will increase the damage of muscle cells in the body, and lactic acid and other substances in the blood and tissues increase, which is why we always feel sore after exercise. Similarly, if we carry out some of their usual exercise before the physical examination, or overeating, will often lead to the physical examination report, some of the more sensitive indicators exceed the standard or positive performance. In the face of this situation, people’s first feeling is what I have this disease, serious or not. And did not consider whether it is their own reasons for false positives. The current study found that: strenuous exercise, fever or infection may cause false positive urine protein items, and need to be reviewed to rule out. And strenuous exercise, holding urine, and around the time of a woman’s physiological period can cause a false positive for red blood cells in the urine. The correct preparation for the physical examination is: fasting from food and water, bed rest, avoiding overeating or physical exercise 12 hours before the day before the physical examination.
