Clinical Significance
Measurement of total protein in urine is important in the diagnosis and treatment of diseases associated with renal, cardiac, and thyroid function. These diseases are often characterized by proteinuria of which there are four main types: (a) glomerular proteinuria - increased glomerular permeability, (b) tubular proteinuria - defective tubular reabsorption, (c) overload proteinuria – increased concentration of low molecular weight protein, (d) postrenal proteinuria - abnormal secretion of protein into the urinary tract. Increased levels of urinary protein may also be present following strenuous exercise or in the following conditions: monoclonal gammopathies, nephritis, diabetic nephropathy, or urinary tract infections.
