Test Details
Methodology
Protein electrophoresis on agarose media; agarose gel immunofixation (IFE) if reflexed
Result Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
24-Hour urine protein electrophoresis with interpretation and automatic reflex to urine immunofixation (at an additional charge) if M-spike is present.
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 proteins.
Special Instructions
For random specimens, order test 003715.
