[Analysis of proteinuria].

Targeted urine screening surveys for risk groups are beneficial. The measurement of microalbuminuria has become an established method for the screening and monitoring of diabetic nephropathy. If strip testing has revealed albuminuria in a symptomless subject as an incidental finding, a first-voided morning urine specimen will be reassayed for albumin. If the strip test result is repeatedly positive, elucidation of the extent of proteinuria is essential. Proteinuria can be divided into glomerular, tubular and overflow proteinuria. Persistent proteinuria is an important clinical finding having significant predictive value for the health and future of a person being examined.
