Clinical Significance
The filtration and resorption of plasma proteins in the formation of urine are important functions of the intact, healthy kidney. The presence of elevated concentrations of protein in urine (proteinuria) is a key finding in primary renal disease of glomerular, tubular, or mixed origin. Proteinuria is also seen in patients with systemic disorders that affect the kidneys such as diabetes mellitis, hypertension, vascular disease, neoplasia, drug toxicity, and certain infectious diseases. Proteinuria may also exist as either a benign or transient condition.
