Protein Electrophoresis With Interpretation, 24-Hour Urine
Also known as: Interpretation, Protein Electrophoresis, Urine
Use
Work up myeloma, macroglobulinemia of Waldenström, 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.
Special Instructions
Not provided.
Limitations
The test may not detect all proteinuria cases as the sensitivity of electrophoretic methods is limited. It also does not provide specific identification of anomalous proteins and is primarily used for screening elevated protein levels in urine rather than for detailed protein characterization.
