I want to ask: Is protein in urine harmful to health?

Under normal circumstances, due to the filtration of glomerular filtration membrane and the reabsorption of renal tubules, the content of protein (mostly small molecular weight protein) in urine of healthy people is very small (the daily output is less than 150).

Mg), qualitative examination of protein, negative reaction.

Under pathological conditions, such as kidney diseases, the filtration effect of filtration membrane will change. One of the typical diagnostic criteria of chronic nephritis, purpura nephritis, lupus nephritis and diabetic nephropathy is that proteinuria and hematuria are abnormal at the same time in routine urine examination, and nephropathy is highly suspected.
