Urine protein positive must be kidney disease?

Urine protein positive does not necessarily mean kidney disease.

Under normal circumstances, urine contains only a small amount of protein, most of which is reabsorbed after glomerular filtration. When kidney problems occur, glomerular filtration of protein increases, resulting in increased protein concentration in urine, urine protein positive. In addition to kidney disease, strenuous exercise before examination, resulting in renal vascular congestion, spasm, urine protein positive. If hemolytic anemia, multiple myeloma and other diseases occur, resulting in increased protein content in the blood, urine protein positive will also occur. Urine protein positive

can be identified by blood tests, imaging tests and other medical examinations, if it is caused by disease, it is recommended to intervene as soon as possible.
