Test ID: MPTS    
M-Protein Isotype, Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry, Serum

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.

Specimen Type Describes the specimen type validated for testing
