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. MGUS causes no symptoms. Beaumont-Epinette MP, Moreau C, Besnard S, Latute F, Collet N, Sebillot M, et al. The lab will also treat the gel so that it only keeps . 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. 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. All rights reserved. In: Ferri's Clinical Advisor 2019. The names of these subsets are based on the method that is used to separate and differentiate the various serum components. Sign-upto receive the latest news on BCIT. Immunofixation "fixes" certain proteins into place with antibodies and then washes away the others before staining them. Your doctor can use it to confirm certain diagnoses. Synonym (s): paraprotein (2) . Less than 10% plasma cells are present in bone marrow, and patients have no lytic bony lesions, anemia, hypercalcemia, or renal insufficiency.

[QxMD MEDLINE Link]. Affected patients have hyperviscosity and hypercellular bone marrow with extensive infiltration by lymphoplasma cells. 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. Monoclonal gammopathy of undetermined significance (MGUS) care at Mayo Clinic. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. This usually takes less than five minutes. Many subspecialists. Healthline Media does not provide medical advice, diagnosis, or treatment. Some people experience mild pain when the needle is inserted. The peaks for these components lie toward the negative electrode, with the gamma peak being closest to that electrode. Contact a health care provider if you have questions about your health. Blood is collected in a tube with clot activator. The next most common type is light chain myeloma in which no intact immunoglobulin is produced. 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. Learn why immunohistochemistry is the gold standard in testing for certain diseases, including several cancers. [Full Text]. Malignant plasma cells in the bone marrow 10% or presence of bony or extramedullary plasmacytoma, confirmed by biopsy. Monoclonal protein is the output of myeloma cells in most people with myeloma. A monoclonal protein is produced by the abnormal, cancerous or precancerous cells. Medscape Drugs & Diseases. Figure 1 shows a typical normal pattern for the distribution of proteins as determined by serum protein electrophoresis. Rajhumar SV. Available from: Hinkle J, Cheever K. Brunner & Suddarth's Handbook of Laboratory and Diagnostic Tests. 2019 May 23. Finally, isolated light chain bands, either kappa or lambda, represent more commonly pure kappa or lambda light chain gammopathies or, less commonly, immunoglobulin D (IgD) or immunoglobulin E (IgE) gammopathies. Available from: National Cancer Institute [Internet]. See permissionsforcopyrightquestions and/or permission requests. There is greater than 10 percent plasma cell involvement on bone marrow biopsy. Kaplan JS, Horowitz GL. National Multiple Sclerosis Society; MS Symptoms; [cited 2019 Dec 18]; [about 3 screens]. URL of this page: https://medlineplus.gov/lab-tests/immunofixation-ife-blood-test/. Quantitative determination of the serum M component to demonstrate that an IgG or IgM monoclonal protein is less than 3.0 g/dL or an IgA monoclonal protein is less than 2.0 g/dL, or that a Bence-Jones protein is less than or equal to 1.0 g in a 24-hour urine specimen. If the result is negative, it is safe to conclude that a pure kappa or lambda light chain is present. 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. In healthy individuals, antibodies produced by plasma cells in the bone marrow help this process. 32 health-related programs and part-time courses, BCIT organized a record-breaking pancake breakfast fundraiser, From business to metal fabrication: Former MBA student follows her passion for trades, How Flexible Learning helps build your resume and career, Life at BCIT: International student makes connections and promotes well-being among her peers - Post-Secondary BC, From education to employment: Why international students choose BCIT, Winning at the game of love: An 80s alumni love story, Digital Arts, Media + Design Online Info Session, Technical Writing Flexible Learning Online Info Session, Mass Timber Construction Principles and Practice. There are two main types of proteins in the blood: albumin and globulin. There is less than 10 percent plasma cell involvement on bone marrow biopsy. This process is known as electrophoresis. There are various types of these proteins that fight different types of infections. There are two main types of proteins in the blood: albumin and globulin. These proteins can also be referred to as an M-spike, monoclonal immunoglobulin, or paraprotein. Home Decision Support in Medicine LabMed, Monoclonal gammopathy of unknown significance (MGUS), Low concentration of monoclonal immunoglobulins (LCMI). 2010. San Francisco: Said Support; c2013-2016. 2015 Aug 26. Technique: Collection starts early in the morning after the first morning urine has been voided and continues for the subsequent 24 hours, including the first morning urine of the following day. M protein is made by abnormal plasma cells. Further investigation will usually be needed to make a definitive diagnosis. Subsequent immunofixation with electrophoresis identified the monoclonal protein as an IgG antibody (paraprotein) with a lambda light chain (arrow). Bone marrow testing involves two steps usually done at the same time in a doctor's office or a hospital: The diagnosis of myeloma depends on three main findings: Revised International Myeloma Working Group (IMWG) Criteria for the Diagnosis of Multiple Myeloma. 1998.

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. [1] In the former, the serum is applied to an agarose gel, and the negatively charged serum proteins move toward the cathode under the influence of an electric current. Copyright 2023 American Academy of Family Physicians. You can also contact us directly if you need to. Eric B Staros, MD Associate Professor of Pathology, St Louis University School of Medicine; Director of Clinical Laboratories, Director of Cytopathology, Department of Pathology, St Louis University Hospital Your doctor may recommend SPEP if you are experiencing symptoms of a condition affecting the proteins in your blood serum. Available from: Lab Tests Online [Internet]. Autoinflammatory vs. Autoimmune: What is the Difference? [QxMD MEDLINE Link]. If abnormal, the curve may be delineated in the wrong location(s) and should be fixed before the result is filed. The serum immunofixation test is most often done with a blood sample. [9]. Haematologica. Monoclonal gammopathies are conditions in which abnormal proteins are found in the blood. In some cases, the test is done with a urine sample. Fortunately, the cause of an abnormal curve is not always pathologic. M-protein is an antibodyor part of an antibodythat can show up in tests of your blood and/or urine, and its presence can mean different things. Serum Protein Electrophoresis (SPEP) Test; [cited 2021 Aug 9]; [about 3 screens]. 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. Washington D.C.: American Association for Clinical Chemistry; c20012019. StatPearls. Blood Cancer J. Accessed April 18, 2019. This so-called acute-reaction protein pattern involves increases in fibrinogen, alpha1-antitrypsin, haptoglobin, ceruloplasmin, CRP, the C3 portion of complement, and alpha1 acid glycoprotein. The following table shows what most labs would consider normal results for SPEP testing. This test is called serum protein electrophoresis (SPEP) test. 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. Peaks and valleys in the bands may mean that you may be making too many or too few of certain proteins. Murray DL, Puig N, Kristinsson S, et al. Inflammatory Disease/Inflammation; [cited 2019 Dec 18]; [about 3 screens]. Testing a 24-hour urine sample allows for an accurate measurement of the level of kidney function and can indicate possible kidney damage from myeloma. The remainder had hypogammaglobulinemia or a normal-appearing pattern. All of these measurements provide information about the extent of the disease and are useful for monitoring response to treatment. Available from: Straub RH, Schradin C. Chronic inflammatory systemic diseases: An evolutionary trade-off between acutely beneficial but chronically harmful programs. Blood appears to be a single substance to the naked eye. Detection of oligoclonal bands in cerebrospinal fluid by immunofixation electrophoresis. 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. Accessed April 18, 2019. [9], In addition, immunofixation can be used to monitor therapy in plasma cell dyscrasias (ie, multiple myeloma and Waldenstrom macroglobulinemia). Again, the lanes are broad and the transition to the lane borders is smooth. Cytogenetic Analysis. Yet, every person's myeloma is unique. 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. These tests also can identify the specific protein type involved in your high blood protein levels. No abstract available. Available from: National Cancer Institute [Internet]. People with monoclonal gammopathy generally don't experience signs or symptoms. Monoclonal gammopathy of undetermined significance (MGUS). My first week back in Chem was spent on the electrophoresis bench. Monoclonal gammopathy of undetermined significance (MGUS) and smoldering (asymptomatic) multiple myeloma: IMWG consensus perspectives risk factors for progression and guidelines for monitoring and management. There are two types of light chains, referred to as kappa (k) and lambda ().. Morris C, Drake M, Apperley J, et al. . Please confirm that you would like to log out of Medscape. Medscape Drugs & Diseases. Protein Electrophoresis questions. This causes the different types of proteins to move and group together. The stained gel is then sent to a pathologist for diagnosis. A hair strand drug test can be used to detect drugs used over the past 90 days. This pattern represents the presence of polyclonal immunoglobulin. 2011. Keep in mind that these are just clues. Hemoglobin is a substance in your red blood cells (blood cells that carry oxygen through your body) that carries oxygen from your lungs to the tissues in your body. One of the best ways to get a better sense of the SPEP test is to look at each word in the name: Serum is the liquid part of your blood. Then it says: "The SPE pattern appears essentially unremarkable. On the left a serum protein electrophoresis (SPEP) of a patient with a monoclonal band in the gamma region is shown. BCIT students get their phlebotomy competencies signed off during a two-week placement in Level 1, so whether you collect blood during the long block practicum is very much dependent on the practicum site. 2019 Jan. [QxMD MEDLINE Link]. Sample size: Every drop of urine within 24 hours is included in the sample. This monoclonal gammopathy occurs in younger patients. These values may vary slightly from facility to facility. Its not always obvious what high or low protein levels in the blood serum may mean. Protein Electrophoresis; p. 430. The identification of a monoclonal immunoglobulin is helpful in the diagnosis of the following conditions Here are my blood test results for "Interpretation" part. Bird J, Behrens J, Westin J, et al. Urine Test. The identification of a monoclonal gammopathy depends on serum and urine protein electrophoresis and immunoelectrophoresis (IFE) 1 and/or quantitative free light chain assays. Protein electrophoresis immunofixation electrophoresis. If the curve is relatively normal (e.g. Goldman L, et al., eds. Alexandria (VA): American Society of Clinical Oncology; 20052019. These tests are done in conjunction with immunofixation for example, serum immunofixation electrophoresis (SIFE), which identifies immunoglobulins in blood samples. A decreased alpha1-protein band may occur because of alpha1-antitrypsin deficiency or decreased production of the globulin as a result of liver disease. Immunofixation in CSF for the detection of oligoclonal bands is indicated every time there is suspicion for multiple sclerosis. Several subsets of serum protein electrophoresis are available. Available from: https://ufhealth.org/protein-electrophoresis-serum. In: Goldman-Cecil Medicine. Continuing Medical Education (CME/CE) Courses. [Full Text]. [10, 17], A 24-hour concentrated urine sample is appropriate for urine immunofixation. Many subspecialists include serum protein electrophoresis screening in the initial evaluation for numerous clinical conditions. [10], Primary screening for plasma cell dyscrasias, No studies have addressed the role of serum or urine immunofixation in screening of the general population for multiple myeloma and related disorders. Burns also may result in a low albumin level. Madison (WI):University of Wisconsin Hospitals and Clinics Authority; c2021. Clinical course and management of monoclonal gammopathy of undetermined significance. This whole (intact) immunoglobulin, made of the four chains, is usually too large to pass through the kidney. 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. Washington D.C.: American Association for Clinical Chemistry; c20012019. correct number of peaks and protein values), the analyzer does a pretty good job of identifying each fraction. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic Press. 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. Other more-specific tests, including serum protein electrophoresis (SPEP), can help determine the exact source, such as liver or bone marrow. Bone marrow aspirate may be useful to show that at least 10% of the nucleated blood cells are plasma cells. Monoclonal antibodies could be used as myeloma treatments and can be identified by serum protein electrophoresis and immunofixation electrophoresis. Available from: Lab Tests Online [Internet]. The next five components (globulins) are labeled alpha1, alpha2, beta1, beta2, and gamma. Immunoglobulin-related amyloidosis. These tests are performed when the IFE blood test doesn't give . This abnormal protein is formed within your bone marrow, the soft, blood-producing tissue that fills in the center of most of your bones. Platelets Small substances in your blood that help the blood to form a thickened mass (or blood clot) to help stop bleeding. Proteins play many important roles, including providing energy for the body, rebuilding muscles, and supporting the immune system. This allows them to be measured and analyzed individually. The examination also should be considered in other red flag situations (Table 1).24, If the examination is normal but multiple myeloma, Waldenstrms macroglobulinemia, primary amyloidosis, or a related disorder still is suspected, immunofixation also should be performed because this technique may be more sensitive in identifying a small monoclonal (M) protein.5. The Leukemia & Lymphoma Society is a 501(c)(3) organization, and all monetary donations are tax deductible to the fullest extent allowed by tax laws. There are five types of heavy chains, and each type is represented by a specific letter: IgG, IgA, IgD, IgE and IgM. How is a urine sample collected for an immunofixation test? A serum thyroxine-binding globulin (TBG) level test is a blood test that measures the amount of TBG in your blood. 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. Keywords: bone marrow; monoclonal protein; multiple myeloma; protein electrophoresis; serum free light chains. Among these, the committee stated that in the detection of monoclonal immunoglobulins, intact light-chain matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) mass spectrometry can be used in lieu of immunofixation in patient clinical assessments and in assessing clinical trial patients. This is a test that determines whether abnormal plasma cells are present in a liquid sample of bone marrow aspirate or blood. Cavuoti D, Baskin L, Jialal I. An accurate diagnosis is one of the most important aspects of a persons medical care. 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. An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. Other names: serum protein electrophoresis, (SPEP), protein electrophoresis, SPE, immunofixation electrophoresis, IFE, serum immunofixation. The proteins create separate bands on the gel, which are then analyzed by the laboratory. No monoclonal band is identified.

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. See why Myeloma protein might show up in your blood and what kinds of conditions it might be a sign of. Consensus recommendations for standard investigative workup: report of the International Myeloma Workshop Consensus Panel. This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. 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. There may be some slight bruising afterward. Head over to share your story and tell us about it. The proteins are separated into 5 or 6 fractions and displayed as a curve and corresponding gel pattern. A homogeneous immunoglobulin resulting from the proliferation of a single clone of plasma cells that; during electrophoresis of serum, appears as a narrow band or "spike"; it is characterized by heavy chains of a single class and subclass, and light chains of a single type. This is a normal serum protein electrophoresis (SPE) pattern; also listed are a few of the proteins associated with each fraction. [14], Mass spectrometry is sometimes employed in place of immunofixation because of the latters limitations, such as in the detection of low-level disease. Fanning SR, Hussein MA. If serum protein electrophoresis is abnormal at any time during the follow-up, a referral should be made.
