Must be urine routine this test we are no strangers to it, it can be said that almost every time you go to the hospital physical examination of the necessary items, but have you ever had questions: how to stay in the urine? What time period is better? Will eating or exercising have any effect? Can you drink more water before leaving the urine? …… Then today, with you to talk about the small talk about it! Urine routine retention method: 1, do general urine routine examination, retain urine specimen can be any time period of urine, but the first urine specimen in the early morning is the most ideal. Because the morning urine is more concentrated and acidic, there are relatively more and complete formed components, no dietary interference, does not affect the urine chemical determination. 2, retained urine specimens, should be tested within one hour, so as not to be placed for too long, the cellular components of the urine by the specific gravity of urine and the influence of acidity and alkalinity and dissolution of the destruction or wrinkled deformation. 3, stay urine should pay attention to should first discharge some urine, the urethral opening of the dirty first rinse, stay in the middle of the urine, and try to avoid menstrual blood, leukorrhea, semen, feces and so on into the mix. 4, the volume of urine should reach one-third of the capacity of the urine cup to ensure the correctness of the test results. The method of retaining 24-hour urine protein The significance of 24-hour urine protein test: It is a necessary test for diagnosing kidney disease and hypertension and other diseases. Its advantage is that the test results are accurate and reliable, and are relatively less affected by external factors such as diet and urine output; the disadvantage is that it requires 24 hours of urine, which is a bit troublesome for the patients who visit the clinic. Common mistake: keep more urine The doctor simply said “keep urine from 6:00 am today to 6:00 am tomorrow” when he wrote the lab order. So many patients will leave the urine of these two 6 o’clock. In fact, if you went to bed at 10:00 last night and urinated once, and did not urinate again until 6:00 this morning, then leave all of this urine is actually a 32-hour urine specimen. Misconception Leave less urine Some patients forget to catch the urine when they have a bowel movement or forget to leave it when they are busy while they are out and about, and then some of the urine is not left behind. Myth It is recommended that patients who need to leave a 24-hour urine specimen should not go out on the day of retention if possible, or bring a retention container if they have to go out. Interference of diet, exercise, etc.: Since the excretion of proteinuria is affected by factors such as diet and exercise, it is important to control these factors during the retention period. Some patients in order to retain urine will stay 24-hour urine specimen on the day deliberately drink more water, in fact, this is completely unnecessary, the patient just need to eat a normal diet, do not need to drink more water, and do not need to deliberately eat more or less protein and other nutrients. Do not engage in strenuous exercise such as running, basketball, soccer, etc. on the day of urine retention; however, antihypertensive drugs can be taken as usual. If there are fever, diarrhea and other conditions, it is recommended to wait until these conditions disappear before retaining urine. The correct method of retention: 1, 6:00 a.m. when the urine will be discharged, discarded; 6:00 a.m. after the urine all collected in a large, clean, dry container until 6:00 a.m. the next day, and the last urine will be discharged into the container. 2. Mix all the urine well, measure the total urine volume with a measuring device and record it on the laboratory slip; or weigh the net weight of all the urine with a scale and record it on the laboratory slip, and then take a specimen of about 20 milliliters from the mixed urine and put it in a clean and dry container and send it to the hospital for examination as soon as possible.
