Test Overview
Immunofixation
To detect clonal light chains. Useful in characterizing the species of protein in cases of proteinuria. Techniques can identify intact monoclonal protein and free light chains (Bence Jones protein). Of value in the study of monoclonal gammopathies and lymphoproliferative diseases, including lymphoma, multiple myeloma and Waldenstrom’s macroglobulinemia. Urine immunofixation is essential in amyloidosis or if a monoclonal band is present on urine protein electrophoresis.
Negative for Bence Jones protein (no clonal free light chains identified). Pathologist interpretation of results provided.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Specimen Requirements
Collect first morning void urine specimen (preferred), preservative free. A 24 hour or random urine, preservative free, is also acceptable. Refrigerate up to 1 week.
