Description
Normally, practically all blood plasma proteins do not pass through the renal glomerular membrane and are detected in urine in trace amounts. With impaired renal filtration function, protein begins to pass through the membrane and is determined in urine in diagnostically significant concentrations. High protein content in urine is a nonspecific sign of kidney diseases; it can also be caused by infectious-inflammatory processes in the urinary tract or tissue breakdown. In some physiological conditions, an increase in urine protein levels may be observed. Such conditions include "march" proteinuria (appearance of protein in urine after prolonged walking), orthostatic proteinuria (after a sudden change in body position); protein in urine may also appear after strong physical and emotional stress. In these cases, the amount of protein excreted in urine per day remains within normal values.
