It is also used to evaluate nephrotic syndromes; work up other renal diseases, including malignant hypertension, glomerulonephritis, Goodpasture syndrome, cryoglobulinemia, toxemia of pregnancy, drug nephrotoxicity, and renal tubular lesions; manage myeloma and macroglobulinemia of Waldenstrom (Bence Jones proteinuria); evaluate hypoproteinemia; tubular proteinurias, including Wilson's disease and Fanconi syndrome. Urinary albumin (microalbumin) is a more sensitive marker of progression and regression of renal disease than urine total protein, especially when urine total protein is <300 mg/g creatinine.
