Analysis of normal values ​​of 24-hour urine protein quantitative

What is the normal value of 24-hour urine protein quantification? Looking at the surface, it should be a measurement indicator, which should be collected to measure the health of a certain part of the body. The exact meaning of this medical term still requires professional explanation, so let’s take a look at the analysis of the normal value of 24-hour urine protein quantification.

A concept

1. 24-hour urine protein quantification refers to a urine testing method that can reflect renal function by collecting all urine excreted within 24 hours, measuring the 24-hour urine volume, and quantifying the protein in the urine.

2. The "24-hour urine volume" in the 24-hour urine protein quantification refers to the amount of urine retained from the second urination after the first urination in the morning. Record the time of your first urination until this time the next day, for a total of 24 hours. Put all the urine within the past 24 hours into a container, mix them evenly, then extract 100 to 200 ml from the middle and take it to the hospital for testing.

2. Collect specimens

Some kidney diseases often require a "24-hour urine protein quantification" test. So how do you collect urine samples for testing?

In order to accurately measure the 24-hour urine protein quantity, the urine in the bladder should be emptied and discarded at 8 o'clock in the morning, and the timer should be started. All the urine discharged in the 24 hours should be stored in a container (including the urine discharged at 8 o'clock the next morning) and all should be sent for examination. If you have a bowel movement within these 24 hours, it is also emphasized that urine should be collected first, and then the bowel movement. Do not miss even small amounts of urine. If the urine volume is not collected completely, the calculation of urine protein amount will be inaccurate. Before testing, you should first use a measuring cup to measure the total urine volume, then stir it evenly, take out a small cup to measure the amount of protein per 100 ml, and then calculate based on the actual urine volume to calculate the amount of protein in 24 hours. In short, to accurately measure the amount of urine protein in 24 hours, the entire day's urine volume must be accurately collected, and the test part must be a mixture of the total urine volume to be representative.

Because this test calculates the absolute value of urine protein, it has little to do with the amount of water you drink. Therefore, there is no need to restrict water and food intake on the day of the test. You can eat as usual.

Three normal values

The normal value of 24-hour urine protein is less than or equal to 0.15g.

After reading the above content, you will have some understanding of the determination method of the normal value of 24-hour urine protein quantification and the related content of the normal value. The importance of this indicator is self-evident. If someone wants to do this kind of examination, then read the above article more and you will know what to expect in the hospital, so you can be mentally prepared in advance. Everyone should take good care of their health.
