Test ID: SPISO    
Protein Electrophoresis and Isotype, Serum

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

This test includes total protein, serum protein electrophoresis, and heavy and light chain typing (kappa and lambda).

 

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.

 

The following algorithms are available in Special Instructions:

-Laboratory Approach to the Diagnosis of Amyloidosis

-Laboratory Screening Tests for Suspected Multiple Myeloma

Specimen Type Describes the specimen type validated for testing

Serum

Advisory Information

To monitor a patient with an established diagnosis of a monoclonal gammopathy, order MMOGA / Monoclonal Gammopathy Monitoring, Serum.

 

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.
