Title

PROTEIN ELECTROPHORESIS, URINE RANDOM

Specimen Requirement

Random urine submitted in sterile urine screw-capped urine container.

Methodology

Stability

Refrigerated 7 days

Reference Range

By Report*

Turnaround

24 hours

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.
