This content does not have an English version. 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. Immunoglobulins are secreted by plasma cells, a type of white blood cell in the bone marrow, in response to infection and disease. If the curve is relatively normal (e.g. Less than 10% plasma cells are present in bone marrow, and patients have no lytic bony lesions, anemia, hypercalcemia, or renal insufficiency. Immunofixation tests can also be done in urine. Each plasma cell produces one of five types of antibodies: IgG, IgA, IgM, IgE or IgD, and either kappa or lambda. Immune Thrombocytopenia Purpura (ITP): What helps? 135:1048-51. If the repeat examination is abnormal or future patterns are abnormal, the next step is to refer the patient to a hematologist-oncologist. 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. Reference Range Immunofixation consists of an electrophoresis phase and a fixation phase. what does no apparent monoclonal protein on serum electrophoresis mean. What is the clinical application of an immunofixation test? 2011. The SFLC assay can detect abnormal levels of free light chains, which may be an indication of a plasma cell disorder.

An endoscopy is used in a wide range of testing throughout the body. [20]. This is a broad term encompassing a number of modern technologies that increase the speed and reduce the cost of DNA sequencing to look for mutations. MGUS is usually detected by chance when you have a blood test for another condition. Peaks and valleys in the bands may mean that you may be making too many or too few of certain proteins. During the fixation phase, antiserum containing anti-IgG, anti-IgA, anti-IgM, anti-light chain kappa, or anti-light chain lambda is inoculated with the serum proteins. A small number of patients with myeloma have either "oligosecretory disease," in which the detectable level of monoclonal protein is low, or "nonsecretory disease," in which no monoclonal protein can be detected. The remainder had hypogammaglobulinemia or a normal-appearing pattern.
In addition, a beta2 microglobulin test, a CRP test, and a 24-hour urine collection for electrophoresis and immunofixation should be performed. 2015 Oct. 47 (6):564-9. When might mass spectrometry be used in place of immunofixation? Instead, they only make light chains. Medscape Drugs & Diseases. Affected patients have no M protein in their urine, no lytic bone lesions, no anemia, no hypercalcemia, and no renal disease. Peripheral blood contains more than 20 percent plasma cells. M-protein level is greater than 3 g per dL. What specimens can be used to perform an immunofixation test? Bone marrow examination may be informative. Rarely, plasma cells can enter into the circulation and if they represent 20 percent or more of the blood cells, the condition is called plasma cell leukemia. Note that the percent of plasma cells in the bone marrow, assessed by flow cytometry, is not the value used in the diagnostic criteria above. In some cases, the test is done with a urine sample. We've rounded up the best at-home kidney health test kits. There are various types of these proteins that fight different types of infections.

An additional point to consider is the size of the M-protein spike. Monoclonal bands are usually seen in the zone but may be seen in proximity of the band or, rarely, in the 2 region. These measurements indicate the degree to which the myeloma cells in the marrow are affecting normal blood cell development.
M Protein (Myeloma Protein): Definition, Test, and Levels - WebMD correct number of peaks and protein values), the analyzer does a pretty good job of identifying each fraction. Further separation of protein subtypes is achieved by staining with an immunologically active agent, which results in immunofluorescence and immunofixation. Many subspecialists include serum protein electrophoresis screening in the initial evaluation for numerous clinical conditions. Yet, every person's myeloma is unique. In zone electrophoresis, for example, different protein subtypes are placed in separate physical locations on a gel made from agar, cellulose, or other plant material.2,3 The proteins are stained, and their densities are calculated electronically to provide graphical data on the absolute and relative amounts of the various proteins.

Approximately 40 percent of myeloma cases are characterized by the presence of trisomies (three copies of a chromosome) in the malignant plasma cells, while in most of the rest there is a translocation involving chromosome 14 (the site of a gene for the immunoglobulin heavy chain). Twenty-four-hour Bence-Jones protein determinations: can we ensure accuracy?.
Difficulties in immunofixation analysis: a concordance study - Nature A decreased alpha1-protein band may occur because of alpha1-antitrypsin deficiency or decreased production of the globulin as a result of liver disease. 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. Diagnosis of monoclonal gammopathy of undetermined significance. In addition to SPEP followed by immunofixation, quantitative serum immunoglobulin should be performed, because the M component must be greater than3 g/dL in the serum. Diseases that produce an increase in the gamma-globulin level include Hodgkins disease, malignant lymphoma, chronic lymphocytic leukemia, granulomatous diseases, connective tissue diseases, liver diseases, multiple myeloma, Waldenstrms macroglobulinemia, and amyloidosis.3,7, Although many conditions can cause an increase in the gamma region, several disease states cause a homogeneous spike-like peak in a focal region of the gamma-globulin zone (Figure 2). If the result is negative, it is safe to conclude that a pure kappa or lambda light chain is present. The following imaging tests are a very important part of the diagnosis, staging and management of myeloma: If you're diagnosed with myeloma, you may need to undergo more tests during or after treatment to see how themyeloma cells are responding to therapy.
