Additional Codes
Torrance Memorial Laboratories Test Code: 4835417569
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.
Specimen Required
Supplies: Sarstedt Aliquot Tube, 5 mL (T914)
Container/Tube: Plastic vial
Preferred: Serum gel
Acceptable: Red top
Specimen Volume: 2 mL total in 2 separate plastic vials, each containing 1 mL
Collection Instructions: Centrifuge and aliquot serum into 2 plastic vials, each containing 1 mL
Useful For
Aiding in the diagnosis and monitoring 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
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.
