[Protein-creatinine ratio--a simple method for proteinuria assessment in clinical practice].

Background: Proteinuria is an indicator of renal disease. Measurement of protein excretion is important for diagnosis and follow-up of renal disease, but measuring 24-hour protein excretion is a cumbersome procedure.

Material And Methods: A simplified validated method for measuring excretion is obtained by measuring urine protein/creatinine concentration in a spot urine sample.
