There are many symptoms in the early stage of kidney disease, and urine protein is one of the important indicators of kidney disease. As an independent factor affecting renal function, urine protein also affects the development and prognosis of subsequent disease.

Which index can judge the severity of urine protein?

In routine urine tests, the urine protein on the laboratory sheet shows "-," which means negative, that is, normal. If it is shown as "1+, 2+, 3+, 4+", it indicates positive, that is, the presence of leak protein in the urine. Many patients usually think that the more the plus sign, the more it is. The more serious the proteinuria, in fact, this is a mistake, because the urine protein in routine urine examination, may be affected by some factors, such as drinking water, urine, sweat, and so on.

Which index can judge the severity of urine protein? 

Key to see 24 hours urine protein quantification. determine whether nephropathy occurs or not, The qualitative index of urine protein is usually said to be negative or positive. If the result of urine protein test is positive, The quantitative determination of urinary protein can more accurately reflect the renal function of the subjects. The commonly used diagnostic index is 24 hours urinary protein quantification.

A urine routine protein test does not represent the condition of the patient's urine protein. However, the 24-hour urine protein quantification is the examination of the patient's urine protein situation throughout the day, which is not easily affected by other factors and is more accurate. It is an important index to judge the severity of urine protein, and the quantitative determination of urine protein can more accurately reflect the renal function of the tested person.

There were three levels of proteinuria: less than 1 g / 24 h for mild proteinuria, 1 g / 3.5 g / 24 h for moderate albuminuria, > 3.5 g / 24 h for severe proteinuria.

Although 24-hour urinary protein quantification is a reliable indicator to determine whether nephropathy occurs or not, the abnormal results of a 24-hour urinary protein quantitative examination alone determine that the subject developed kidney disease. This is not accurate. In clinical diagnosis of the occurrence of nephropathy, it is usually necessary to repeat routine urine examination. By doing regular examinations, the patient's urine routine examination results show that, The 24-hour urinary protein quantitative indexes with three or more times were higher than the normal reference range.
