Proteinuria is an important indicator of underlying kidney disease and its presence and quantity is an independent risk factor for both progression of CKD and cardiovascular disease. Routine urinalysis for screening purposes is recommended for high risk patients particularly those with diabetes or hypertension. Furthermore changes in proteinuria have been suggested as a surrogate outcome for kidney disease progression. This article will review the evaluation of a patient with isolated proteinuria and the way of screening and measuring for proteinuria will be explained here.
