Quick highlights
- Supports detection/assessment of urine light chains (Bence Jones proteins)
- Used in selected hematology evaluation pathways with serum tests
- Collection method may be spot or 24-hour—follow instructions closely
- No fasting required
- Interpretation requires clinical context and confirmatory serum studies
- Often reviewed with kidney function tests and protein electrophoresis
- Useful for monitoring when ordered by hematologist
- Home pickup possible after urine collection (service-area dependent)
- Clear limitations prevent self-diagnosis

It depends on the clinician/lab request; follow the instructions for your order.
No.
Use a clean container and follow lab instructions; for spot urine, midstream collection is commonly advised.
Serum protein electrophoresis, immunofixation, serum free light chains, CBC, kidney function tests.
Kidney function can influence protein handling; clinicians interpret results with kidney markers.
Often same day or within 24 hours depending on method.
Yes in many areas after you complete urine collection (service-area dependent).
