Test Code QMPSS Monoclonal Protein Study, Quantitative, Serum


Ordering Guidance


 



Additional Testing Requirements


Quantitation of monoclonal protein alone is not considered an adequate screen for monoclonal gammopathies. When screening a patient or establishing a first-time diagnosis for a monoclonal gammopathy, order FLCS / Immunoglobulin Free Light Chains, Serum in addition to this test.

Preferred: Serum gel

Acceptable: Red top

Submission Container/Tube: Plastic vial

Testing Algorithm

This test includes quantitation of monoclonal-protein isotype and immunoglobulins G, A, and M.

 

If a light chain is identified without a corresponding heavy chain during initial testing, then immunofixation with immunoglobulin D (IgD) and immunoglobulin E (IgE) will be performed at an additional charge.

 

If a monoclonal IgD or IgE is identified during initial testing, then IgD or IgE testing will be performed at an additional charge.
