If you have high amounts of this protein in your blood, it's important to have regular checkups so that you can get earlier treatment if it does progress. The identification of a monoclonal immunoglobulin is helpful in the diagnosis of the following conditions 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. correct number of peaks and protein values), the analyzer does a pretty good job of identifying each fraction. A homogeneous spike-like peak in a focal region of the gamma-globulin zone indicates a monoclonal gammopathy. Evidence of end-organ damage as defined by the CRAB criteria. StatPearls. The albumin band represents the largest protein component of human serum. If the result is negative, it is safe to conclude that a pure kappa or lambda light chain is present. Its not always obvious what high or low protein levels in the blood serum may mean. Cancer.Net [Internet]. In other cases, patients may have non-specific symptoms, meaning the discovery of a protein band in the serum . When a narrow band with sharp borders can be identified, it implies the presence of a monoclonal protein (see image below). Clinical course and management of monoclonal gammopathy of undetermined significance. Factors that increase your risk of developing MGUS include: Each year about 1% of people with MGUS go on to develop certain types of blood cancers or other serious diseases such as: Other complications associated with MGUS include bone fractures, blood clots and kidney problems. Sample: Serum (whole blood or plasma is inappropriate, as fibrinogen may alter the results), Sample: 24-hour urine collection, concentrated. 133 (25):2664-8.

This article provides a comprehensive review of serum protein electrophoresis, including a discussion of how the examination is performed, what it measures, and when it is indicated. This test is called serum protein electrophoresis (SPEP) test. [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. If the curve is relatively normal (e.g. 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 There are various types of these proteins that fight different types of infections. Both of the following criteria must be met: In healthy individuals, plasma cellsproduce proteins called polyclonal immunoglobulins. These are a collection of antibodies that protect the body against all kinds of different invading viruses, bacteria or other infectious agents (antigens). Monoclonal light chains also called or Bence Jones protein, are seen in the urine of Multiple myeloma cases in 75 % of the patients. The test may also be performed again in the future. Each plasma cell produces one of five types of antibodies: IgG, IgA, IgM, IgE or IgD, and either kappa or lambda. https://www.uptodate.com/contents/search.

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. Philadelphia: Wolters Kluwer Health, Lippincott Williams & Wilkins; c2014. Peripheral blood smear often shows RBC aggregates in a rouleaux formation. Bird J, Behrens J, Westin J, et al. Available from: National Cancer Institute [Internet]. There are two types of light chains, referred to as kappa (k) and lambda ().. This allows them to be measured and analyzed individually. 2017 Dec 28. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Is there something going on we should know about? The search for meaning in monoclonal protein. Is it multiple - PubMed Accessed April 18, 2019. AskMayoExpert. Most patients with untreated myeloma have a monoclonal immunoglobulin spike in serum, urine, or both. Kaplan JS, Horowitz GL. A monoclonal spike (M spike or paraprotein) on serum protein electrophoresis (SPEP) is a frequent finding in the general population and typically is pathognomonic of an asymptomatic, premalignant condition called monoclonal gammopathy of undetermined significance (MGUS). But sometimes it can progress to more-serious diseases, including some forms of blood cancer. IgA or IgM bands are less common. Affected patients have only one tumor, with no other bone lesions and no urine or serum abnormalities. 95:2126-33. Some. Your results will show that your protein levels are in the normal range, too high, or too low. There are five types of heavy chains, and each type is represented by a specific letter: IgG, IgA, IgD, IgE and IgM. Complete Blood Count (CBC). Thanks for helping me with this quality post. Low concentration of monoclonal immunoglobulins (LCMI) Heavy chain disease Suggested Additional Lab Testing For multiple myeloma: In addition to SPEP followed by immunofixation, quantitative. [QxMD MEDLINE Link]. 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. Morris C, Drake M, Apperley J, et al. 2011. 2nd Ed, Kindle. Other more-specific tests, including serum protein electrophoresis (SPEP), can help determine the exact source, such as liver or bone marrow. It may also depend on the unique patterns made by the proteins. Philadelphia, Pa.: Elsevier; 2019. https://www.clinicalkey.com. These measurements indicate the degree to which the myeloma cells in the marrow are affecting normal blood cell development. M protein is made by abnormal plasma cells. Monoclonal gammopathy of undetermined significance. Flow Cytometry. This process is known as electrophoresis. A serum thyroxine-binding globulin (TBG) level test is a blood test that measures the amount of TBG in your blood. [13, 14], Diagnosis of plasma cell dyscrasias 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. Lahuerta JJ, Jimenez-Ubieto A, Paiva B, et al. They have a number of roles: Too much or too little protein can cause problems. Electrophoresis is not usually used by itself to diagnose a disease. Please check with your financial advisor if you have more questions. Albumin, the largest peak, lies closest to the positive electrode. In some patients, the myeloma cells do not make a complete monoclonal immunoglobulin molecule with two heavy and two light chains. The output of monoclonal protein can vary from patient to patient. Making sense of serum protein bands. Also, the level of protein being excreted in the urine and the amount of light chains can be measured. Leukemia. Your story might just end up on BCIT News. What does no monoclonal protein detected mean - DQKD Bethesda (MD): U.S. Department of Health and Human Services; NCI Dictionary of Cancer Terms: leukemia; [cited 2019 Dec 10]; [about 3 screens]. Luzzio C, Dangond F. Multiple sclerosis. People with monoclonal gammopathy generally don't experience signs or symptoms. Blood is collected in a tube with clot activator.

The most common type of myeloma is IgG kappa, occurring in approximately 52 % of patients. Plasma protein levels display reasonably predictable changes in response to acute inflammation, malignancy, trauma, necrosis, infarction, burns, and chemical injury. Arch Pathol Lab Med. 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 Synonym (s): paraprotein (2) . M protein is an abnormal protein caused by plasma cells. The pattern of serum protein electrophoresis results depends on the fractions of two major types of protein: albumin and globulins. LLS funds lifesaving blood cancer research around the world, provides free information and support services, and is the voice for all blood cancer patients seeking access to quality, affordable, coordinated care. Ronald Hoffman, Leslie E. Silberstein, Sanford J. Shattil, Bruce Furie, Philip McGlave. Instead, they only make light chains. Protein electrophoresis alone is not considered an adequate screen for monoclonal gammopathies. Peripheral blood smear often shows RBCs in a stacked or rouleaux formation. Less than 10% plasma cells are present in bone marrow, and patients have no lytic bony lesions, anemia, hypercalcemia, or renal insufficiency. 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. 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. Its a useful skill to maintain, as technologists especially those on off-shifts or at smaller sites may still collect through their career(s). Medscape Drugs & Diseases. 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). Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. High blood protein When to see a doctor - Mayo Clinic Bone Marrow Tests. These tests are performed when the IFE blood test doesn't give . Myelomacells produce many copies of its anibody. Finally, the sample is washed to remove the proteins that do not precipitate and then stained, destained, and dried. Next-Generation Sequencing (NGS). SPEP and UPEP don't measure myeloma cells; they measure the output of myeloma cells. Monoclonal gammopathy of undetermined significance (MGUS). Tests are done to measure the levels of many different substances in the blood. Blood. Bone marrow examination may be informative. 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. 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. Immunofixation: Reference Range, Interpretation, Collection and Panels Abnormalities in any of these tests should result in a referral to a hematologist-oncologist. Another test, calledimmunofixation or immunoelectrophoresis, is used to determine the exact type ofabnormal antibody (IgG. If there are not CRAB signs and/or symptoms, 60% plasma cells in the bone marrow indicates a diagnosis. Youve read {{metering-count}} of {{metering-total}} articles this month. There are a number of reasons why a doctor may order this test. Blood. The gamma-globulin zone is decreased in hypogammaglobulinemia and agammaglobulinemia. This is a normal serum protein electrophoresis (SPE) pattern; also listed are a few of the proteins associated with each fraction. Peripheral blood contains more than 20 percent plasma cells. Rochester (NY): University of Rochester Medical Center; c2019. Diagnosis is often done with a lab test called electrophoresis. 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. Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. 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). Monoclonal gammopathy of undetermined significance. Available from: National Heart, Lung, and Blood Institute [Internet].

Washington D.C.: American Association for Clinical Chemistry; c20012019. Accessed April 18, 2019. Proteins are substances made of small chemicals called amino acids. These so-called monoclonal gammopathies constitute a group of disorders that are characterized by proliferation of a single clone of plasma cells that produce a homogeneous M protein.6, It is extremely important to differentiate monoclonal from polyclonal gammopathies. Protein electrophoresis immunofixation electrophoresis. Are you a BCIT News insider? 2015 Aug 26. In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process. Sample size: Every drop of urine within 24 hours is included in the sample. To confirm the former and because of the latter, if there is a high index of clinical suspicion, immunofixation studies are required. [14], Mass spectrometry is sometimes employed in place of immunofixation because of the latters limitations, such as in the detection of low-level disease. Protein Electrophoresis questions. 1976. 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. Other inflammatory conditions of the CNS can present with oligoclonal bands in CSF resulting from intrathecal production of antibodies. 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. 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. The peaks for these components lie toward the negative electrode, with the gamma peak being closest to that electrode. Symptoms of malnutrition or malabsorption include: A health care professional will take a blood sample from a vein in your arm, using a small needle. This causes the different types of proteins to move and group together. [15], However,a study by Lahuerta et al indicated that, with the exception of persons with light-chainonly disease, urine immunofixation is not needed in combination with serum immunofixation to define complete response in multiple myeloma. IgA or some other type). Cavuoti D, Baskin L, Jialal I. How is a urine sample collected for an immunofixation test? 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. Myeloma Protein (M Protein): What Is It? | MyMyelomaTeam Available from: National Cancer Institute [Internet]. Inflammatory Disease/Inflammation; [cited 2019 Dec 18]; [about 3 screens]. Urine protein electrophoresis (UPEP) is, C-reactive protein is produced by the liver in response to inflammation. Genetic changes and environmental triggers appear to play a role. Role of urine immunofixation in the complete response assessment of MM patients other than light-chain-only disease. That criteria is determined by a pathologist who reviews the bone marrow aspirate slides. [Full Text]. Lab Tests Online [Internet]. The serum immunofixation test is most often done with a blood sample. Immunofixationconsists of an electrophoresis phase and a fixation phase. Yang G, Geng C, Chen W. Clinical characteristics of a group of patients with multiple myeloma who had two different light chains by immunofixation electrophoresis: A retrospective study from a single center. 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.

Dimopoulos M, Kyle R, Fermand JP, et al. Available from: https://ufhealth.org/protein-electrophoresis-serum. Sometimes a CBC with differential (CBC with diff), a test that also measures the number of the different types of white blood cells present in the blood, is ordered. The LLS mission: Cure leukemia, lymphoma, Hodgkin's disease and myeloma, and improve the quality of life of patients and their families. Fortunately, the cause of an abnormal curve is not always pathologic. Symptoms and Causes Diagnosis and Tests Management and Treatment Prevention Outlook / Prognosis https://www.uptodate.com/contents/search. A C-reactive protein test, or CRP test, measures the amount of CRP in your. A colonoscopy is specifically used to look at the colon. What is the reference range of an immunofixation test? Follow our channels and share your own adventure. 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. Medscape Drugs & Diseases. Immunofixation can either reveal a normal pattern or identify a monoclonal protein or a polyclonal immunoglobulin pattern. It can also detect changes in the ratio of kappa and lambda light chain production, which indicates an excess of abnormal plasma cells. Want to view more content from Cancer Therapy Advisor? Peaks and valleys in the bands may mean that you may be making too many or too few of certain proteins. [3], Waldenstrom macroglobulinemia Thus, it is most often present in the blood but not in the urine. [10]. The presence of M proteins can be a sign of a type of cancer called myeloma, or multiple myeloma. Multiple Myeloma: Symptoms and Signs; 2016 Oct [cited 2019 Dec 10]; [about 3 screens]. Your use of this website constitutes acceptance of Haymarket Medias Privacy Policy and Terms & Conditions. One pathologic reason which we covered at BCIT is a monoclonal gammopathy. This sample is often difficult to collect, and suboptimal collection might alter the result. [Full Text]. 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. Connect with others like you for support and answers to your questions in the Blood Cancers & Disorders support group on Mayo Clinic Connect, a patient community. Monoclonal gammopathies of undetermined significance. M-protein level is usually greater than 3 g per dL. The Licensed Content is the property of and copyrighted by DSM. 109:585-8. An endoscopy is used in a wide range of testing throughout the body. National Multiple Sclerosis Society; MS Symptoms; [cited 2019 Dec 18]; [about 3 screens]. 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. 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. Albumin, the major protein component of serum, is produced by the liver under normal physiologic conditions. The remainder had hypogammaglobulinemia or a normal-appearing pattern. The subgroups are: Measuring the proteins in each subgroup can help diagnose a variety of diseases. These tests also can identify the specific protein type involved in your high blood protein levels. Protein Electrophoresis; p. 430. So when the Serum Protein Electrophoresis (SPEP) test shows a spike in M protein, this is a sign of MM. Your doctor may recommend SPEP if you are experiencing symptoms of a condition affecting the proteins in your blood serum. Immunofixation (IFE) Blood Test: MedlinePlus Medical Test [9]. 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. Monoclonal Immunoglobulin (Ig), Monoclonal antibody, Immunofixation Comparison of the Freelite serum free light chain (SFLC) assay with serum and urine electrophoresis/immunofixation and the N Latex FLC assay.
