Aid in the diagnosis of monoclonal gammopathies, including multiple myeloma, when clinical pretest probability is low. Use to detect and quantify serum monoclonal protein. Immunofixation is performed if patterns from SPEP are monoclonal or suspicious.
Quantitative Capillary Electrophoresis/Qualitative Immunofixation Electrophoresis/Quantitative Nephelometry/Quantitative Spectrophotometry
Serum Separator Tube (SST).
Separate from cells ASAP or within 2 hours of collection. Transfer 1.5 mL serum to an ARUP Standard Transport Tube. (Min: 1.5 mL)
After separation from cells: Ambient: Unacceptable; Refrigerated: 1 week; Frozen: 1 month

Immunofixation electrophoresis is a more sensitive technique than serum protein electrophoresis for the identification of small M-proteins found in patients with amyloidosis, early or treated myeloma and macroglobulinemia, MGUS, solitary plasmacytoma, and extramedullary plasmacytoma.
No compliance statements are in use for this test.
If patterns from serum protein electrophoresis are monoclonal or suspicious, then Immunofixation Electrophoresis will be added. Additional charges apply.
IFE is a more sensitive method for determining and defining monoclonal proteins. No additional testing will be added for proteins that are normal, polyclonal, or that lack monoclonal patterns.
