Test Name: Monoclonal Protein Quantitation, Urine, 24 Hour
Health Link Test Code: HCULCT
LIS Test Code: ULCT

Urine protein electrophoresis and a quantitative urine protein.
Methodology: Gel Electrophoresis
Urine protein electrophoresis is used to quantitate monoclonal light chain bands previously identified by urine immunofixation.
Days Performed: Mon-Fri, dayshift - day varies.
In-Lab Turnaround Time: 3 - 5 days.
Stat In-Lab Turnaround Time: Not available stat.
Specimen: 24 hour timed urine
Collection Container: 24 hour urine container
Collection Volume: Entire collection
3 months for concentrated sample
Sample Analyzed: Urine aliquot
Testing Volume: 10 mL
Pediatric Testing Volume: 10 mL
Outreach Specimen Processing:
Send aliquot from a well-mixed 24 hour collection in a sterile container with a coolant pack.
Transport entire collection to Laboratory at close of collection.
Random urine collections.
Urines with preservatives.
Urines with bloody supernatants are acceptable but not desirable.
Urines with no previously identified monoclonal proteins.
A written interpretive report with the scan is issued as a separate report.
The total urine protein method may underestimate the tubular and light chain protein fractions causing an underestimate in the semi-quantitative protein values reported by electrophoresis. The percent relationship of light chain proteins to tubular proteins and the ability to detect light chains is not affected.
Monoclonal Protein Urine Electrophoresis requests more frequent than 14 days will automatically be cancelled by the laboratory system.
A professional fee is associated with this test.
