When these are removed, a liquid is left behind. The test may also be performed again in the future. My first week back in Chem was spent on the electrophoresis bench. The precise cause of MGUS isn't known. Medscape Drugs & Diseases. Accessed April 18, 2019. In: Ferri's Clinical Advisor 2019. 22:1262-8. Rochester (NY): University of Rochester Medical Center; c2019. The pattern of serum protein electrophoresis results depends on the fractions of two major types of protein: albumin and globulins. That criteria is determined by a pathologist who reviews the bone marrow aspirate slides. Inflammatory Disease/Inflammation; [cited 2019 Dec 18]; [about 3 screens]. The released hemoglobin can also bind to haptoglobin, a protein in the 2 fraction, forming a hemoglobin-haptoglobin complex that blurs the 2 and separation and may resemble a malignant peak. Leukemia. Lab Tests Online [Internet]. In some cases, the test is done with a urine sample. This test measures the numbers of red blood cells, white blood cells and platelets in the blood. In some patients, the myeloma cells do not make a complete monoclonal immunoglobulin molecule with two heavy and two light chains. This is a test that determines whether abnormal plasma cells are present in a liquid sample of bone marrow aspirate or blood. The proteins create separate bands on the gel, which are then analyzed by the laboratory. Affected patients have only one tumor, with no other bone lesions and no urine or serum abnormalities. However, most patients with a monoclonal protein will be finally diagnosed with MGUS rather than any of the malignant plasma cell dyscrasias for which treatment is recommended. When a narrow band with sharp borders can be identified, it implies the presence of a monoclonal protein (see image below). Available from: Straub RH, Schradin C. Chronic inflammatory systemic diseases: An evolutionary trade-off between acutely beneficial but chronically harmful programs. Medscape Drugs & Diseases. 2023 Healthline Media LLC. excess of an abnormal immunoglobulin called monoclonal protein (or M protein). A hair strand drug test can be used to detect drugs used over the past 90 days. Continuing Medical Education (CME/CE) Courses. 2017 Dec 28. Genetic changes and environmental triggers appear to play a role. Monoclonal gammopathies 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. Tax Identification Number: 13-5644916, Myeloma Guide: Information for Patients and Caregivers, A bone marrow aspirationto remove a liquid marrow sample, A bone marrow biopsyto remove a small amount of bone filled with marrow, Malignant plasma cells: Plasma cell level of >10% in a bone marrow biopsy sample, Unusually large amounts of monoclonal protein (called an M spike). 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. A polyclonal gammopathy is characterized by a broad diffuse band with one or more heavy chains and kappa and lambda light chains.7, Once a monoclonal gammopathy is identified by serum protein electrophoresis, multiple myeloma must be differentiated from other causes of this type of gammopathy. Serum protein electrophoresis (SPEP) and urine protein electrophoresis (UPEP) are tests in which proteins in blood and urine samples are separated so that individual antibodies can be identified and quantified. [16]. Protein Electrophoresis questions. An endoscopy is used in a wide range of testing throughout the body. What does "polyclonal light chains detected but no monoclonal immunoglobilin or free light chain (bencejones) is MD presence of free light chain in urine is diagnostic of multiple myeloma.Multiple myeloma is a type of cancer that is caused by malignant plasma cells that proliferate in the bone marrow and produce abnormally high amounts. No abstract available. 2018 Dec 3. https://www.merckmanuals.com/professional/hematology-and-oncology/plasma-cell-disorders/monoclonal-gammopathy-of-undetermined-significance-mgus?query=mgus. If the result is negative, it is safe to conclude that a pure kappa or lambda light chain is present. Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. Cavuoti D, Baskin L, Jialal I. These tests are done in conjunction with immunofixation for example, serum immunofixation electrophoresis (SIFE), which identifies immunoglobulins in blood samples. Immunoglobulins, known as Igs, are a group of proteins that help protect your body from illness. This is serum. Washington D.C.: American Association for Clinical Chemistry; c20012019. In other cases, patients may have non-specific symptoms, meaning the discovery of a protein band in the serum . These symptoms could include the following: Some of the conditions that could be causing these symptoms are: No preparation is needed for the test. When screening a patient or establishing a first-time diagnosis for a monoclonal gammopathy, consider ordering DMOGA / Monoclonal Gammopathy, Diagnostic, Serum instead, which includes free light chain analysis. The various proteins in the body perform different functions. Immunofixation "fixes" certain proteins into place with antibodies and then washes away the others before staining them. Pathology. The following table shows what most labs would consider normal results for SPEP testing. Electrophoresis is a method of separating proteins based on their physical properties. 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. MGUS is usually detected by chance when you have a blood test for another condition. Evol Med Public Health. This sample is often difficult to collect, and suboptimal collection might alter the result. This causes the different types of proteins to move and group together. 2011. 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. Morrow ES Jr. Allscripts EPSi. [ 1] Serum or urine immunofixation negative for a monoclonal protein or a polyclonal pattern is. Immunofixation tests can also be done in urine. 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. what does no apparent monoclonal protein on serum electrophoresis mean. IgA, IgM, and sometimes IgG, along with complement proteins, also can be identified in the beta fraction. These values may vary slightly from facility to facility. Since the expression levels of these genes and how mutations in them, if present, influence the behavior of the myeloma cells, these techniques may be helpful in better predicting treatment outcomes and developing new and improved targeted therapies. Immunofixation electrophoretic techniques applied to identification of proteins in serum and cerebrospinal fluid. Rajhumar SV. No monoclonal band is identified. There is greater than 10 percent plasma cell involvement on bone marrow biopsy. Alpha-1 Antitrypsin; [updated 2019 Nov 13; cited 2019 Dec 10]; [about 2 screens]. 1976.

[QxMD MEDLINE Link]. Some immunoglobulins can be abnormal and may be due to cancer. Share cases and questions with Physicians on Medscape consult. Monoclonal antibodies could be used as myeloma treatments and can be identified by serum protein electrophoresis and immunofixation electrophoresis. Characteristic differentiating features of the monoclonal gammopathies are listed in Table 4.7, In some patients with a plasma cell dyscrasia, serum protein electrophoresis may be normal because the complete monoclonal immunoglobulin is absent or is present at a very low level.7 In one series,6 serum protein electrophoresis showed a spike or localized band in only 82 percent of patients with multiple myeloma. Electrophoresis separates proteins based on their physical properties, and the subsets of these proteins are used in interpreting the results. The identification of a monoclonal immunoglobulin is helpful in the diagnosis of the following conditions URL of this page: https://medlineplus.gov/lab-tests/immunofixation-ife-blood-test/.

The LLS mission: Cure leukemia, lymphoma, Hodgkin's disease and myeloma, and improve the quality of life of patients and their families. There are two types of light chains, referred to as kappa (k) and lambda ().. Monoclonal gammopathies are associated with a clonal process that is malignant or potentially malignant, including multiple myeloma, Waldenstrms macroglobulinemia, solitary plasmacytoma, smoldering multiple myeloma, monoclonal gammopathy of undetermined significance, plasma cell leukemia, heavy chain disease, and amyloidosis. Surveillance for multiple myeloma in patients with MGUS and favorable prognostic factors (ie, low levels of monoclonal protein and IgG type) should include monitoring at 6 months and then every 2-3 years thereafter. Your results will show that your protein levels are in the normal range, too high, or too low. Luzzio C, Dangond F. Multiple sclerosis. These include an elevated protein level, anemia and abnormalities in kidney function or calcium levels. The proteins are separated into 5 or 6 fractions and displayed as a curve and corresponding gel pattern. Proteins play many important roles, including providing energy for the body, rebuilding muscles, and supporting the immune system. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Is there something going on we should know about?

Malignancy and acute inflammation (resulting from acute-phase reactants) can increase the alpha1-protein band. However, you shouldnt have a lot of protein in your urine. Br J Haematol. Available from: National Heart, Lung, and Blood Institute [Internet]. 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). Monoclonal protein (M protein) levels can be measured in blood and/or urine samples,and these levels generally correlate with the extent of the myeloma. Flow Cytometry. An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. Here are my blood test results for "Interpretation" part. Thus, it is most often present in the blood but not in the urine. Symptoms and Causes Diagnosis and Tests Management and Treatment Prevention Outlook / Prognosis Anastasios Dimou, MD Resident Physician, Department of Internal Medicine, Albert Einstein Medical CenterDisclosure: Nothing to disclose. 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. Instead, they only make light chains. Sometimes, however, the results of this examination can be confusing or difficult to interpret. This can help the doctor decide how well therapies and medicines are working. Also, M proteins may not be apparent on electrophoresis. Affected patients have no lytic bone lesions, no anemia, no hypercalcemia, and no renal disease. John C Leighton, Jr, MD, FACP Clinical Associate Professor, Jefferson Medical College of Thomas Jefferson University; Chief, Division of Medical Oncology, Jeanes Hospital; Associate Director, Associate Chief, Divisions of Hematology/Medical Oncology, Albert Einstein Cancer Center; Associate Member Kimmel Cancer Center, Thomas Jefferson Hospital Peripheral blood smear often shows RBC aggregates in a rouleaux formation. 2015 Oct. 47 (6):564-9. Serum is placed on a specific medium, and a charge is applied. When the whole immunoglobulin is present in the urine, it is usually at a low level. Next-generation sequencing is being done now on a research basis but may soon be used in routine clinical practice. Low concentration of monoclonal immunoglobulins (LCMI) Heavy chain disease Suggested Additional Lab Testing For multiple myeloma: In addition to SPEP followed by immunofixation, quantitative. A small number of patients with myeloma have either oligosecretory disease, inwhich the detectable level of monoclonal protein is low, or nonsecretory disease,in which no monoclonal protein can be detected. Available from: Lab Tests Online [Internet]. A monoclonal protein is produced by the abnormal, cancerous or precancerous cells.

This test is most often used to help diagnose or monitor a variety of different conditions. There are a number of reasons why a doctor may order this test. If the sample is hemolyzed in vitro (red blood cells are ruptured outside the body such as during traumatic blood draw), there will be free hemoglobin, which migrates to the 1 fraction. The beta fraction has two peaks labeled beta1 and beta2. Pathol Biol (Paris). In most cases in which a monoclonal protein is present, it shows as a narrow band at the IgG lane in combination with a monoclonal band at the kappa or lambda lane. Twenty-four-hour Bence-Jones protein determinations: can we ensure accuracy?. [12] an additional assay for the identification of IgD or IgE must be performed. 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.
