Test Details
Methodology
Urine immunofixation (IFE) on agarose gel; urine protein electrophoresis on agarose media; visual light-chain typing
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
α1-Globulin, urine; α2-globulin, urine; β-globulin, urine; γ-globulin, urine; M-spike percentage; protein immunofixation, urine
Use
Characterize the species of protein or proteins in cases of proteinuria. Techniques can identify albumin, γ-globulin, γ-globulin fragments (light chains, Bence Jones proteins); of value in the study of monoclonal gammopathies, lymphoproliferative diseases, including lymphoma; special application to multiple myeloma, macroglobulinemia of Waldenström, and amyloidosis; work up monoclonal gammopathy (M-spike)
Special Instructions
The request form should include patient's age and clinical diagnosis.
