Protein Electrophoresis Urine Test, Random
A protein electrophoresis urine test is a graph with quantitation of total urine protein, urine albumin, urine N1, urine N2, urine N3-globulin fractions if present; quantitation (in %) of M-spike if present.
Evaluate myeloma, macroglobulinemia of Waldenstrom, lymphoma, amyloidosis; differentiate between normal renal function, glomerular proteinuria, and tubular proteinuria. Increased glomerular permeability leads to higher concentrations of large proteins in the glomerular filtrate. Diminished tubular reabsorptive capacity results in a marked increase in urinary excretion of low molecular weight problems.
