Test Catalog

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

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

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


This test alone is not considered an adequate screen for monoclonal gammopathies

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

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.
