M protein is an abnormal protein caused by plasma cells. Monoclonal gammopathy of undetermined significance (MGUS) and smoldering (asymptomatic) multiple myeloma: IMWG consensus perspectives risk factors for progression and guidelines for monitoring and management. [Full Text]. Serum protein electrophoresis is the easiest means of excluding the presence of a monoclonal protein and can detect bands of 0.5 gm/dL or less. However, blood has several components. There is very little risk to having a blood test. [QxMD MEDLINE Link]. 2017 Dec 28. Patients with monoclonal gammopathy of undetermined significance require close follow-up because about 1 percent per year develop multiple myeloma or another malignant monoclonal gammopathy.13 [Evidence level B, prospective cohort study] An algorithm for the follow-up of patients with a monoclonal gammopathy is provided in Figure 3.6. The speed of movement is dictated by their charge. Bone marrow examination may be informative. Other names: serum protein electrophoresis, (SPEP), protein electrophoresis, SPE, immunofixation electrophoresis, IFE, serum immunofixation. The alpha1-protein fraction is comprised of alpha1-antitrypsin, thyroid-binding globulin, and transcortin. 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. Monoclonal gammopathy of undetermined significance (MGUS). Each plasma cell produces one of five types of antibodies: IgG, IgA, IgM, IgE or IgD, and either kappa or lambda. The protein electrophoresis test is often used to find abnormal substances called M proteins. A polyclonal immunoglobulin pattern in the serum or urine immunofixation is considered to be nonspecific. This whole (intact) immunoglobulin, made of the four chains, is usually too large to pass through the kidney. In: Ferri's Clinical Advisor 2019. Ceruloplasmin, alpha2-macroglobulin, and haptoglobin contribute to the alpha2-protein band. The presence of M proteins can be a sign of a type of cancer called myeloma, or multiple myeloma. Autoinflammatory vs. Autoimmune: What is the Difference? Monoclonal gammopathy of undetermined significance (MGUS) is a condition in which an abnormal protein known as monoclonal protein or M protein is in your blood. Sample: Serum (whole blood or plasma is inappropriate, as fibrinogen may alter the results), Sample: 24-hour urine collection, concentrated. The Licensed Content is the property of and copyrighted by DSM. 2021 Feb 1. Your results will show that your protein levels are in the normal range, too high, or too low. The remainder had hypogammaglobulinemia or a normal-appearing pattern. 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). (2015, August 21). The procedure was nearly identical to one of our labs at BCIT, so Im glad to have had a bit of experience in preparing the gel and dispensing the antisera. Levels of albumin are increased in patients with a relative reduction in serum water (e.g., dehydration). Both types of blood cells (red and white) and platelets are solids. The region is sometimes divided into 1 and 2, which would account for a sixth fraction. Typically, the monoclonal protein is discovered, and workup then ensues. Urine immunofixation uses electricity to push proteins from your urine sample through a kind of gel. 2011. Immunoglobulins are secreted by plasma cells, a type of white blood cell in the bone marrow, in response to infection and disease. This website also contains material copyrighted by 3rd parties. For patients with MGUS and high risk for progression to multiple myeloma, surveillance should be performed at 6 months and then yearly thereafter. These tests also can identify the specific protein type involved in your high blood protein levels. An additional point to consider is the size of the M-protein spike. 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. Alpha-1 Antitrypsin; [updated 2019 Nov 13; cited 2019 Dec 10]; [about 2 screens]. C-reactive protein (CRP) is located in the area between the beta and gamma components.1, Serum protein electrophoresis commonly is performed when multiple myeloma is suspected. Lahuerta JJ, Jimenez-Ubieto A, Paiva B, et al. The gamma-globulin zone is decreased in hypogammaglobulinemia and agammaglobulinemia. Monoclonal gammopathies are associated with a clonal process that is malignant or potentially malignant. Immunofixation in CSF for the detection of oligoclonal bands is indicated every time there is suspicion for multiple sclerosis. 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. San Francisco: Said Support; c2013-2016. URL of this page: https://medlineplus.gov/lab-tests/immunofixation-ife-blood-test/. Flow Cytometry. Twenty-four-hour Bence-Jones protein determinations: can we ensure accuracy?. A C-reactive protein test, or CRP test, measures the amount of CRP in your. 5 fractions are shown in this image: albumin, alpha-1 ( 1 ), alpha-2 ( 2 ), beta () and gamma (). Proteins play many important roles, including providing energy for the body, rebuilding muscles, and supporting the immune system. Morris C, Drake M, Apperley J, et al. How is an immunofixation test interpreted? Monoclonal antibodies could be used as myeloma treatments and can be identified by serum protein electrophoresis and immunofixation electrophoresis. Peripheral blood smear often shows RBCs in a stacked or rouleaux formation. Immunoglobulins are proteins that function as antibodies, which fight infection. Urbancek S, Gascon P, Schwartz RA, Jacobson DR, Buxbaum JN, Bogdan CA. This sample is often difficult to collect, and suboptimal collection might alter the result. Available from: Lab Tests Online [Internet]. High protein levels may be caused by many conditions. Goldman L, et al., eds. If the repeat examination is abnormal or future patterns are abnormal, the next step is to refer the patient to a hematologist-oncologist. The subgroups are: Measuring the proteins in each subgroup can help diagnose a variety of diseases. Its not always obvious what high or low protein levels in the blood serum may mean. Madison (WI):University of Wisconsin Hospitals and Clinics Authority; c2021. Monoclonal proteins can be either intact monoclonal immunoglobulins or immunoglobulin light chains (Bence Jones proteins) found in the blood and/or urine. A total protein test can determine whether you have high blood protein. Copyright 2017, 2013 Decision Support in Medicine, LLC. Under the PE Value it says: "SPE1". In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process. The IFX test can also be used to study changes in the structure of normal. The following table shows what most labs would consider normal results for SPEP testing. People with monoclonal gammopathy generally don't experience signs or symptoms. Dimopoulos M, Kyle R, Fermand JP, et al. Guido Tricot. The patient urinates each time into a clean dry vessel and then pours the urine in the plastic container, which is kept at a cold temperature (eg, in the refrigerator). You are being redirected to Blood. Multiple Myeloma. 1 It's called a monoclonal . Definition. In some cases, all the lanes are homogeneously darkened to the same degree. Health Encyclopedia: Immunofixation (Blood); [cited 2019 Dec 10]; [about 2 screens]. Finally, the sample is washed to remove the proteins that do not precipitate and then stained, destained, and dried. Common causes of low levels include: Your diagnosis will depend on which specific protein levels were not normal, and whether the levels were too high or too low. Affected patients have only one tumor, with no other bone lesions and no urine or serum abnormalities. Kidney or liver disease, a condition involving inflammation, poor nutrition, Disease leading to inflammation (condition may be chronic or acute), Liver disease, congenital emphysema (rare), Kidney disease, disease leading to inflammation (condition may be chronic or acute), Liver disease, poor nutrition, breakdown of red blood cells, Anemia, multiple myeloma, high cholesterol, Rheumatoid arthritis, infection, liver cirrhosis, inflammatory disease, multiple myeloma, lymphoma.

This abnormal protein is formed within your bone marrow, the soft, blood-producing tissue that fills in the center of most of your bones. The SFLC assay can detect abnormal levels of free light chains, which may be an indication of a plasma cell disorder. The identification of a monoclonal immunoglobulin is helpful in the diagnosis of the following conditions [2] : Monoclonal gammopathy of undetermined significance (MGUS) 11 (2):24. If there's no disease progression, MGUS doesn't require treatment. Among these other causes are Waldenstrms macroglobulinemia, solitary plasmacytoma, smoldering multiple myeloma, monoclonal gammopathy of undetermined significance, plasma cell leukemia, heavy chain disease, and amyloidosis.4,7, The quantity of M protein can help differentiate multiple myeloma from monoclonal gammopathy of undetermined significance. Copyright 2005 by the American Academy of Family Physicians. [12] an additional assay for the identification of IgD or IgE must be performed.

If all tests are normal, the pattern of follow-up in Figure 36 can be undertaken. cancer cells lead to abnormal immunoglobulins; their build-up negatively affects the formation and function of normal blood cells, the kidneys, and neurologic state, amongst other things. Healthcare providers treat the underlying cause of the immune response to help treat polyclonal gammopathy. A colonoscopy is specifically used to look at the colon. Blood Cancer J. Urine IFE tests are often done if IFE blood test results were not normal. Keep in mind that these are just clues. Immunofixation tests can also be done in urine. Sample size: Every drop of urine within 24 hours is included in the sample. Also, the level of protein being excreted in the urine and the amount of light chains can be measured. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. 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.

The article also provides a simple guide to result interpretation and suggestions on follow-up of abnormal results. The specimen can be serum, urine, or CSF. In other cases, patients may have non-specific symptoms, meaning the discovery of a protein band in the serum . NGS can identify mutations present in the genes of the myeloma cells. In Kelowna I had the week of review, and go out 2-3 mornings a week while in Chem and Hematology. If Waldenstrms macroglobulinemia or other lymphoproliferative process is suspected, an abdominal computed tomographic scan and bone marrow aspiration and biopsy should be performed. 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.

[QxMD MEDLINE Link]. Evidence of monoclonal protein is not apparent." Abnormal levels of certain chemicals may indicate that an organ is not working properly or they may be caused by cancer or other health conditions. Immunofixation reveals the heavy chain as alpha, gamma, or mu. This test is called serum protein electrophoresis (SPEP) test. There may be some slight bruising afterward. The "M" technically stands for "monoclonal," but M protein is often referred to as myeloma protein. The quantity of M protein, the results of bone marrow biopsy, and other characteristics can help differentiate multiple myeloma from the other causes of monoclonal gammopathy. Globulins comprise a much smaller fraction of the total serum protein content. Available from: National Cancer Institute [Internet]. When might mass spectrometry be used in place of immunofixation? Immunofixationconsists of an electrophoresis phase and a fixation phase. MGUS is characterized by a serum IgG monoclonal protein less than 3.5 g/dL or IgA paraprotein less than 2 g/dL, with no or only a small amount of protein in urine (Bence Jones protein < 1 g/24 hr).

Characterized by a sharp peak in the beta-gamma region, monoclonal gammopathies involve increased production of immunoglobulins, or antibodies (IgA, IgG, IgM, etc.). Advertising revenue supports our not-for-profit mission. When excreted in large amounts, Bence Jones proteins (free light chains) can sometimes make the urine appear foamy and they can cause injury to the kidneys. Much of the clinical interest is focused on the gamma region of the serum protein spectrum because immunoglobulins migrate to this region. Monoclonal light chains also called or Bence Jones protein, are seen in the urine of Multiple myeloma cases in 75 % of the patients. Ramakrishnan N, Jialal I. Bence-Jones Protein. In addition, doctors stagemyeloma to help them decide on the best treatmentplan. The method can be used to examine specific proteins in the blood, urine, and other body fluids.
