Test ID MPTS M-Protein Isotype by Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS), Serum


Specimen Required


Only orderable as part of a profile. For more information see:

SPISO / Protein Electrophoresis and Isotype, Serum

SMOGA / Monoclonal Gammopathy Screen, Serum

MMOGA / Monoclonal Gammopathy Monitor, Serum

 

Patient Preparation: Fasting preferred but not required

Container/Tube:

Preferred: Serum gel

Acceptable: Red top

Specimen Volume: 1 mL


Useful For

Aiding in the diagnosis of monoclonal gammopathies, when used in conjunction with free light chain studies

Testing Algorithm

This test includes M-protein isotyping. 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.
