Monitoring patient's body fluid proteins
Aiding in the diagnosis of monoclonal gammopathies, when used in conjunction with immunofixation of the patient's serum
Detecting oligoclonal banding in spinal fluid (the preferred test for detecting oligoclonal bands in spinal fluid is OLIG / Oligoclonal Banding, Serum and Spinal Fluid)
Body fluid proteins can be grouped into 5 fractions by protein electrophoresis (PEL):
The concentration of these fractions and the electrophoretic pattern may identify abnormalities in the levels of the various fractions.
Protein electrophoresis alone is not considered an adequate screening for body fluid or serum monoclonal gammopathies.
A characteristic monoclonal band (M-spike) is often found in the gamma-globulin region and more rarely in the beta or alpha-2 regions. The finding of a M-spike, restricted migration, or hypogammaglobulinemic body fluid protein electrophoresis pattern is suggestive of a possible monoclonal protein and should be followed by a MPSS / Monoclonal Protein Study, Serum using the patient’s serum, which includes immunofixation to identify the immunoglobulin heavy chain and/or light chain.
Hemolysis may augment the beta fraction.
Penicillin may split the albumin band.
Radiographic agents may produce an uninterpretable pattern.
