Clinical Significance

Detect a monoclonal light chain in the urine of a patient with (or suspected to have) multiple myeloma, macroglobulinemia, amyloidosis, or related disorders.

Abnormal bands in the electrophoretic pattern, primarily those in the beta globulins and gamma globulins zones, are always suspect of being monoclonal proteins and therefore an indication of gammopathies.
