A 24-hour urine retention test is one that requires all urine at a fixed time on day 1, such as 7 a.m., until the same time the next morning.
On the morning of the day when the urine retention should be started a fixed point in time should be fixed, for example, at seven o’clock in the morning, the bladder should be emptied while retaining the urine, and this time the urine volume is not collected and recorded, and after that every urine volume is collected until the same point in time on the next morning after 24 hours, and the total urine volume for 24 hours is recorded, and the urine should be shaken well, and 10 milliliters of it should be taken and submitted to the test.
A large volume container with a capacity of at least 2 to 4 liters should be prepared prior to the 24-hour urine test. Generally, an appropriate amount of preservative, such as toluene, can be added in advance as prescribed by the physician. The choice of container should be clean to avoid urine contamination.
Urine collection records should be accurate so as not to affect the results. In the case of women, the menstrual period should be avoided.
24-hour urine test is mainly used to determine the composition and quality of urine, which is a very important indicator in kidney disease.
If you need to keep 24-hour urine, you need to visit a regular hospital and keep it under the guidance of a physician to improve the accuracy of the test.
