GENERAL NOTES



APPLICATION:  Assessment of renal disease.  Some methods will not detect light chain proteinuria.

INTERPRETATION:  Protein loss in the urine is most commonly due to renal glomerular disease especially if >2 g/24 hours.  Proteinuria of >3 g/24 hours is required to establish the diagnosis of the nephrotic syndrome.  In renal tubular disease, light chain proteinuria, orthostatic proteinuria and myoglobinuria, protein loss is usually <1 g/24 hours.
