If these examinations are normal, serum protein electrophoresis should be repeated in three to six months; if that examination is normal, serum protein electrophoresis should be repeated annually. [Full Text]. Yet, every person's myeloma is unique. In many myeloma patients, the coordinated process of making and attaching light chains and heavy chains fails in the malignant plasma cells. Heavy/light chain specific immunoglobulin ratios provides no additional information than serum proteins electrophoresis and immunofixation for the diagnosis and the follow-up of intact immunoglobulin multiple myeloma patients. Shah D, Seiter K. Multiple myeloma. Follow-up of multiple myeloma, Waldenstrom macroglobulinemia, and AL amyloidosis, Immunofixation of urine and serum samples should be performed in all patients with multiple myeloma, Waldenstrom macroglobulinemia, and AL amyloidosis every 3 months after the completion of treatment in order to evaluate for response or to document a relapse. Finally, when several bands with sharp borders are seen after immunofixation in cerebrospinal fluid (CSF) but not in serum, the result is reported as positive for oligoclonal bands. 2019 Jul 15. These measurements indicate the degree to which the myeloma cells in the marrow are affecting normal blood cell development. If the serum M-protein spike is 1.5 to 2.5 g per dL, it is important to perform nephelometry to quantify the immunoglobulins present and to obtain a 24-hour urine collection for electrophoresis and immunofixation. 2018 Dec 3. IFE classifies the monoclonal based on the type of heavy (IgG, IgA or IgM) and light (kappa or lambda) chains that make up the antibodies. Often, there are associated decreases in the albumin and transferrin levels.6 Table 26 lists characteristic patterns of acute-reaction proteins found on serum protein electrophoresis, along with associated conditions or disorders.

Visual examination of electrophoretic patterns by a pathologist is the most sensitive method of detecting monoclonal proteins since small bands may be obscured in densitometric scans. Bird J, Behrens J, Westin J, et al. Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. Low concentration of monoclonal immunoglobulins (LCMI) Heavy chain disease Suggested Additional Lab Testing For multiple myeloma: In addition to SPEP followed by immunofixation, quantitative. In addition, when protein electrophoresis assays are positive for a monoclonal protein, serum and urine immunofixation are indicated for the appropriate identification of the immunoglobulin and the corresponding light chain. The monoclonal band is seen in: Multiple myelomas show in 99 % of the patients in serum and urine. In myeloma, large amounts of a single antibody are noted as a monoclonal immunoglobulin spike or monoclonal spike (M spike), indicating that the protein came from cells that originally started as single, malignant cell.
