High Resolution Agarose Electrophoresis
Used to differentiate between normal renal function, glomerular proteinuria and tubular proteinuria. Increased glomerular permeability leads to higher concentrations of large proteins in the glomerular filtrate. Severe glomerular basement membrane damage will result in large amounts of polyclonal gammaglobulins being lost in the urine. Diminished tubular reabsorptive capacity results in a marked increase in urinary excretion of low molecular weight proteins.

Preservative-free urine, first AM void preferred (24 hour urine or random urine acceptable). Refrigerate up to 1 week.
Test includes pathologist interpretation of results billed as a separate additional charge. This test is not available without interpretation. In order to provide accurate interpretation, abnormal results will be followed by Bence Jones Protein Screen (urine immunofixation) at an additional charge, if clinically indicated. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
