Test ID: SPEP    
Electrophoresis, Protein, Serum

Useful For Suggests clinical disorders or settings where the test may be helpful

Screening patients with suspected monoclonal gammopathies

 

Diagnosis of monoclonal gammopathies, when used in conjunction with matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and free light chains

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
TPETotal ProteinYes, (Order TP)Yes
SPEProtein ElectrophoresisNoYes

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Test IDReporting NameAvailable SeparatelyAlways Performed
MPTSM-protein Isotype MALDI-TOF MS, SNoNo
IMFXImmunofixationYes, (Order IMFXO)No

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test includes total protein and serum protein electrophoresis.

 

If a discrete electrophoresis band is identified, the laboratory will evaluate the serum protein electrophoresis and, if necessary, perform M-protein isotype at an additional charge.

 

If a light chain is identified without a corresponding heavy chain during initial testing, immunofixation with IgD and IgE antisera will be performed at an additional charge.
