Specimen Requirements
Title
Protein Electrophoresis, Urine Random
Specimen Requirement
Collect first morning urine, mix well, send 12 mL (minimum 6 mL) urine in a sterile container.
Do not use preservative.
Methodology
Electrophoresis on agarose media
Stability
Room temp: 14 days, Refrigerated: 14 days, Frozen: 14 days
Reference Range
The reference range is determined by the performing laboratory and will show on the report.
Turnaround
3-5 days
Clinical Use
Evaluate 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.
