Test ID: MMOGA    
Monoclonal Gammopathy Monitoring, Serum

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

This test includes total protein and serum protein electrophoresis.

 

If a discrete electrophoresis band is not identified, the laboratory will evaluate the serum protein electrophoresis and, if necessary, perform M-protein isotype at an additional charge.

 

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.

 

If a history of an IgD or IgE has been previously established and no M-spike is seen on electrophoresis, immunofixation with IgD and IgE antisera will be performed at an additional charge.

Specimen Type Describes the specimen type validated for testing

Serum

Advisory Information

Protein electrophoresis alone is not considered an adequate screen for monoclonal gammopathies. When screening a patient or establishing a first-time diagnosis for a monoclonal gammopathy, consider ordering SMOGA / Monoclonal Gammopathy Screen, Serum instead, which includes free light chain analysis.
