What is the normal value of urine protein?

Protein content in urine of healthy people is very small (daily output is less than 150 mg), and it is negative when protein is used for qualitative examination. When the urine protein content increases and exceeds 150mg/d, it can be detected by routine urine examination, which is called proteinuria. If the urine protein content is ≥3.5g/24h, it is called massive proteinuria, which is common in patients with nephrotic syndrome.

Extended data There are often quantitative protein in blood, which is indispensable for human life activities. Part of protein will be filtered into the urine in the renal fibroids, but it will be absorbed in the renal tubules and returned to the blood. ?

Therefore, if the function of the kidney is normal, there is only a small amount of protein in the urine, but when there is a problem with the kidney and catheter, a large amount of protein will leak out and become proteinuria. There is a trace protein in the urine of normal people, which is negative within the normal range and is recorded as (-). When the urine protein content is more than 0. 15g/24h, it is called proteinuria, and urine routine can be positive.
