Clinical Significance
Proteinuria, mainly glomerular, is often a manifestation of primary renal disease although transient proteinuria may occur with fevers, thyroid disorders, and in heart disease. In the absence of renal disease, the degree of proteinuria is slight, usually amounting to less than 2 grams per day. In chronic glomerulonephritis and in the nephrotic syndrome including lipoid nephrosis and in some forms of hypertensive vascular disease, protein loss may vary from a few grams to as much as 30 g/day.
