Proteinuria

Proteinuria is an important finding in patients because it may signify either a benign disorder or renal disease. A systematic approach to evaluation, which incorporates a careful clinical evaluation coupled with a few simple laboratory tests, is required to determine whether the patient can be followed, or whether a more invasive study, such as renal biopsy, is indicated. Although the causes of proteinuria are diverse, a structured approach to the patient with proteinuria provides maximal information with minimal expense and risk.
