Clinical Significance
Serum protein electrophoresis (SPE) is an analytical technique that provides separation of serum protein into six fractions: Albumin, Alpha-1, Alpha-2, Beta-1, Beta-2, and Gamma. Interpretation of elevation, decreased, or visual change in different fractions can be used as a diagnostic aid for a variety of different disease states and protein abnormalities, including monoclonal gammopathies (MG).
