How much protein is in normal human urine?

When you go to the hospital for a routine urine test, if the result shows urine protein, the doctor will usually recommend that you continue to do urine protein tests. Generally, a 24-hour urine protein test is required. Only in this way can the test results be accurate. A single test result cannot explain the situation, because there are many reasons for urine protein, such as dietary factors and exercise reasons, etc. So what is the normal urine protein content of a person?

How much protein is in normal human urine?

Under normal circumstances, the 24-hour urine protein quantity is less than 150 mg. Exercise, diet, external environmental stimulation, etc. can also cause protein to appear in urine tests, but under normal circumstances, the 24-hour urine protein quantity is normal.

Guidance:

Nephritis is a common disease that causes proteinuria. Once diagnosed, it is best to choose the appropriate treatment for the patient based on the patient's symptoms. If the patient has dry eyes, blurred vision, dizziness, tinnitus, fever in the five parts of the body, dry mouth and throat, lumbar muscle pain, red and burning urine, irritability and thirst, insomnia, etc., most of them are liver-kidney yin deficiency type nephritis. It is necessary to choose "Chinese patent medicine for the treatment of liver-kidney yin deficiency type nephritis". Choosing Chinese medicine suitable for the patient according to the syndrome type is the basic principle of drug selection for patients with nephritis and the basis for curing proteinuria.

A routine urine test will normally show negative results for urine protein. The presence of urine protein may be caused by strenuous activity, the use of certain medications, and a high-protein diet before the test. However, if urine protein is present in multiple reexaminations, protein loss due to kidney disease should be considered. Further tests of kidney function and 24-hour urine protein quantification can be performed, and further treatment can be conducted after a clear diagnosis based on one's own symptoms.

Normal urine should not contain protein, but the absence of protein in urine does not mean that there is no protein leakage.

Guidance:

You can check for trace protein or 24-hour urine protein, observe the color and texture of urine, whether there is foam, and pay attention to your diet.

Healthy people also excrete some urine protein

Healthy people may also have very small amounts of urine protein, but in a qualitative test, as long as the test paper does not change color and shows a negative result (-), it is considered normal.

In addition, quantitative examination of urine protein content shows that it is within the normal range when it is below 100 mg per day.

In addition, even if there is no physical disorder, urine protein will appear when there is strenuous exercise, extreme cold, mental excitement, or strong stress.
