I think the urine routine test is not unfamiliar to everyone, it can be said that almost every time you go to the hospital for a physical examination of the necessary items, but have you also had questions: how to stay urine? What time period is better? What are the effects of eating or exercising? Can you drink more water before leaving urine? …… Then today, let’s talk about the small talk! The method of retention of urine routine: 1, do the general urine routine examination, retention of urine specimens can be any time of the urine, but the first urine specimens early in the morning is the most ideal. Because the morning urine is more concentrated and acidic, there are relatively more and complete formed fractions, no dietary interference, does not affect the urine chemical determination. 2, retained urine specimens, should be tested within an hour, so as not to be placed too long, the urine cellular components by the urine specific gravity and acidity of the impact of dissolution and destruction or crumpled deformation. 3, when retaining urine should pay attention to should first discharge some urine, the urethral opening of the dirty first rinse clean, retain the middle urine, and try to avoid menstrual blood, leukorrhea, semen, feces and other mixed in. 4, the volume of urine should reach one-third of the volume of the urine cup to ensure the correctness of the test results. The significance of 24-hour urine protein test: It is a necessary test for the diagnosis of kidney disease and hypertension and other diseases. Its advantage is that the test results are accurate and reliable, and are relatively unaffected by external factors such as diet and urine volume; the disadvantage is that 24-hour urine retention is required, which is a bit of a problem for patients. A common mistake: retaining more urine The doctor simply says, “Keep urine from 6:00 a.m. this morning to 6:00 a.m. tomorrow” when issuing the test. So many patients will leave both 6:00 a.m. urine. In fact, if you urinated once last night at 10:00 p.m. when you went to bed and did not urinate again until 6:00 a.m. this morning, you are actually leaving a 32-hour urine specimen if you leave all of this urine. Myth Less urine retention Some patients forget to catch urine when they pass stool or forget to retain urine when they are out and about, so some of the urine is not retained. Myth It is recommended that patients who need to keep urine specimens for 24 hours should not go out on the day of urine retention if possible, or bring a container for urine retention if they have to go out. Interference with diet and exercise: Since the excretion of protein urine in humans is affected by diet and exercise, it is important to control these factors during urine retention. Some patients may drink more water on the day of 24-hour urine retention, but this is not necessary at all. Patients only need to eat normally and do not need to drink more water or eat less protein. On the day of urine retention, do not engage in strenuous exercise such as running, basketball, soccer, etc.; however, antihypertensive drugs can be taken as usual. If you have fever, diarrhea, etc., it is recommended to wait until these conditions disappear before retaining urine. The correct way to retain urine: 1.Discharge and discard urine at 6 am; collect all urine after 6 am in a large, clean, dry container until 6 am the next day, and discharge the last urine into the container. 2. Mix all the urine, measure the total urine volume with a measuring device and record it on the lab sheet; or weigh the net weight of all the urine with a scale and record it on the lab sheet, then take a specimen of about 20 ml 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.
