what does no apparent monoclonal protein on serum electrophoresis mean

In: Goldman-Cecil Medicine. [11] HIV-related encephalitis, neurosyphilis, Lyme meningoencephalitis, neurosarcoidosis, acute disseminated encephalomyelitis (ADEM), systemic lupus erythematosus (SLE), Sjgren syndrome, subacute sclerosing panencephalitis, CNS malignancy, neuromyelitis optica, and transverse myelitis can all reveal oligoclonal banding in CSF immunofixation, precluding the use of immunofixation for the detection of oligoclonal bands as a sole diagnostic technique in multiple sclerosis. It may also depend on the unique patterns made by the proteins. 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. What specimens can be used to perform an immunofixation test? The five groups of proteins usually considered during an SPEP test are: Electrophoresis is a lab technique used to separate groups of proteins in blood serum. Burns also may result in a low albumin level. In some patients, the myeloma cells do not make a complete monoclonal immunoglobulin molecule with two heavy and two light chains.

Monoclonal gammopathies are conditions in which abnormal proteins are found in the blood. Then it says: "The SPE pattern appears essentially unremarkable. Consequently, urine protein electrophoresis is recommended in all patients suspected of having a plasma cell dyscrasia.10. 5 fractions are shown in this image: albumin, alpha-1 ( 1 ), alpha-2 ( 2 ), beta () and gamma (). All rights reserved. Most patients with untreated myeloma have a monoclonal immunoglobulin spike in serum, urine, or both. Serum protein electrophoresis (SPEP) is a laboratory technique thats used to determine the levels of some types of proteins in a blood sample. All rights reserved. Making sense of serum protein bands. An accurate diagnosis is one of the most important aspects of a persons medical care. The following table shows what most labs would consider normal results for SPEP testing. 1998. All material on this website is protected by copyright, Copyright 1994-2023 by WebMD LLC. [10, 17], A 24-hour concentrated urine sample is appropriate for urine immunofixation. M protein is made by abnormal plasma cells. Kaplan JS, Horowitz GL. 147:22-42. 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). When a narrow band with sharp borders can be identified, it implies the presence of a monoclonal protein (see image below).

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. 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. Browse the 32 health-related programs and part-time courses available at BCITs School of Health Sciences. [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. Urine immunofixation uses electricity to push proteins from your urine sample through a kind of gel. Proteins are substances made of small chemicals called amino acids. High protein levels may be caused by many conditions. Healthcare providers treat the underlying cause of the immune response to help treat polyclonal gammopathy. 2010. Figure 1 shows a typical normal pattern for the distribution of proteins as determined by serum protein electrophoresis. Obtaining a precise diagnosis will help the doctor to: The results of blood tests that accompany periodic medical examinations may indicate the need for further evaluation for myeloma. If multiple myeloma still is considered clinically in a patient who does not have an M-protein spike on serum protein electrophoresis, urine protein electrophoresis should be performed. In some cases, all the lanes are homogeneously darkened to the same degree. 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. Urine Test. Gainesville (FL): University of Florida Health; c2021. The disorder occurs most commonly in older men. Mayo Clinic, Rochester, Minn. April 26, 2019. Benign monoclonal proteins were first described by Dr. Jan Waldenstrm in 1960 after he detected abnormal narrow hypergammaglobulinemia bands in serum protein electrophoresis (SPEP) samples from healthy individuals. bone pain. Mayo Clinic College of Medicine and Science, Mayo Clinic Graduate School of Biomedical Sciences, Mayo Clinic School of Graduate Medical Education, Mayo Clinic School of Continuous Professional Development, for Monoclonal gammopathy of undetermined significance (MGUS), Mayo Clinic on Incontinence - Mayo Clinic Press, NEW Mayo Clinic on High Blood Pressure - Mayo Clinic Press, Mayo Clinic on Hearing and Balance - Mayo Clinic Press, FREE Mayo Clinic Diet Assessment - Mayo Clinic Press, Mayo Clinic Health Letter - FREE book - Mayo Clinic Press, Financial Assistance Documents Minnesota, Monoclonal gammopathy of undetermined significance (MGUS), Book: Mayo Clinic Family Health Book, 5th Edition, Newsletter: Mayo Clinic Health Letter Digital Edition, Essential Thrombocythemia: Looking for information and support. Bethesda (MD): U.S. Department of Health and Human Services; NCI Dictionary of Cancer Terms: lymphoma; [cited 2019 Dec 10]; [about 3 screens]. If a monoclonal protein is present, a precipitant will form at this phase. The albumin band represents the largest protein component of human serum. Available from: Maine Health [Internet]. This usually takes less than five minutes. The albumin level is decreased under circumstances in which there is less production of the protein by the liver or in which there is increased loss or degradation of this protein. The Leukemia & Lymphoma Society (LLS) is a global leader in the fight against blood cancer. A normal result includes a darker immunoglobulin G (IgG) lane, a lighter immunoglobulin A (IgA), an absent immunoglobulin M (IgM), and a denser kappa compared to lambda lane, with ratio of 2:1. 2018 Sep 7. Another test, calledimmunofixation or immunoelectrophoresis, is used to determine the exact type ofabnormal antibody (IgG. Available from: National Cancer Institute [Internet]. 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 Immunoglobulins are proteins that function as antibodies, which fight infection. Available from: Hinkle J, Cheever K. Brunner & Suddarth's Handbook of Laboratory and Diagnostic Tests. Alexandria (VA): American Society of Clinical Oncology; 20052019. AskMayoExpert. The test may also be performed again in the future. Therefore, the International Myeloma Working Group Mass Spectrometry Committee created a set of recommendations for the evaluation of monoclonal proteins in multiple myeloma and related disorders, using mass spectrometry. Peaks and valleys in the bands may mean that you may be making too many or too few of certain proteins. There are two main types of proteins in the blood: albumin and globulin. Role of urine immunofixation in the complete response assessment of MM patients other than light-chain-only disease. Some people may experience a rash or nerve problems, such as numbness or tingling. Consensus recommendations for standard investigative workup: report of the International Myeloma Workshop Consensus Panel. Plasma cell disorders. Available from: Lab Tests Online [Internet]. The various proteins in the body perform different functions. Cancer.Net [Internet]. This test is most often used to help diagnose or monitor a variety of different conditions. Some people experience mild pain when the needle is inserted. Blood Chemistry Tests. Sometimes, however, the results of this examination can be confusing or difficult to interpret. Detection of oligoclonal bands in cerebrospinal fluid by immunofixation electrophoresis. Multiple Myeloma. Urine immunoelectrophoresis is a lab test that measures immunoglobulins in a urine sample. If serum protein electrophoresis is abnormal at any time during the follow-up, a referral should be made. [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. 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. MGUS is usually detected by chance when you have a blood test for another condition. 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. The article also provides a simple guide to result interpretation and suggestions on follow-up of abnormal results. Some immunoglobulins can be abnormal and may be due to cancer. Affected patients have no lytic bone lesions, no anemia, no hypercalcemia, and no renal disease. 1976. An M-protein spike of greater than 2.5 g per dL should be assessed with a metastatic bone survey that includes a single view of the humeri and femurs. Tests are done to measure the levels of many different substances in the blood. See additional information. In a normal result, the lanes are broad and there is a gradual and smooth reduction in the color density toward the edges of the lane with no narrow dense band with sharp borders identified within the lane. Monoclonal gammopathies of undetermined significance. 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. [9], Surveillance among patients with MGUS or smoldering (asymptomatic) multiple myeloma, Immunofixation of the urine and serum should be included in a battery of tests after 2-3 months following diagnosis of smoldering myeloma, then every 4-6 months for 1 year, and, finally, every 6-12 months if the results are stable. When these are removed, a liquid is left behind. My first week back in Chem was spent on the electrophoresis bench. Both types of blood cells (red and white) and platelets are solids. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. 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. It can also detect changes in the ratio of kappa and lambda light chain production, which indicates an excess of abnormal plasma cells. These values may vary slightly from facility to facility. 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. 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. A C-reactive protein test, or CRP test, measures the amount of CRP in your. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. 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. You can learn more about how we ensure our content is accurate and current by reading our. Monoclonal gammopathy of undetermined significance. There are a number of reasons why a doctor may order this test. Polyclonal gammopathy, also known as hypergammaglobulinemia, is a condition in which white blood cells make too many proteins (antibodies). Morris C, Drake M, Apperley J, et al. 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. It involves exposing serum placed in a. It should be noted that immunoglobulins often can be found throughout the electrophoretic spectrum. Keywords: bone marrow; monoclonal protein; multiple myeloma; protein electrophoresis; serum free light chains. Instead, its used along with other laboratory tests to provide more information to help with diagnosis. 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. Common causes of high levels include: Low protein levels may be caused by many conditions. However, blood has several components. In other cases, patients may have non-specific symptoms, meaning the discovery of a protein band in the serum . Accessed April 18, 2019. Contact a health care provider if you have questions about your health. To confirm the former and because of the latter, if there is a high index of clinical suspicion, immunofixation studies are required. Next-Generation Sequencing (NGS). 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. Typically, the monoclonal protein is discovered, and workup then ensues. Immunofixation "fixes" certain proteins into place with antibodies and then washes away the others before staining them. Levels of albumin are increased in patients with a relative reduction in serum water (e.g., dehydration). Monoclonal light chains also called or Bence Jones protein, are seen in the urine of Multiple myeloma cases in 75 % of the patients. Shah D, Seiter K. Multiple myeloma. Evol Med Public Health. Peripheral blood smear often shows RBCs in a stacked or rouleaux formation. [18, 19], Detection of a paraprotein by immunofixation is possible in lymphomas. Rochester (NY): University of Rochester Medical Center; c2019. excess of an abnormal immunoglobulin called monoclonal protein (or M protein). Malnutrition; [updated 2019 Nov 11; cited 2019 Dec 10]; [about 2 screens]. If the curve is relatively normal (e.g. Bethesda (MD): U.S. Department of Health and Human Services; NCI Dictionary of Cancer Terms: multiple myeloma; [cited 2019 Dec 10]; [about 3 screens]. The next five components (globulins) are labeled alpha1, alpha2, beta1, beta2, and gamma. One pathologic reason which we covered at BCIT is a monoclonal gammopathy. In addition, doctors stagemyeloma to help them decide on the best treatmentplan. [12] an additional assay for the identification of IgD or IgE must be performed. 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. [QxMD MEDLINE Link]. The disorder occurs most commonly in older men. A total protein test can determine whether you have high blood protein. Sample: Serum (whole blood or plasma is inappropriate, as fibrinogen may alter the results), Sample: 24-hour urine collection, concentrated. A decreased alpha1-protein band may occur because of alpha1-antitrypsin deficiency or decreased production of the globulin as a result of liver disease. This sample is often difficult to collect, and suboptimal collection might alter the result. Affected patients have hyperviscosity and hypercellular bone marrow with extensive infiltration by lymphoplasma cells. 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. Available from: Straub RH, Schradin C. Chronic inflammatory systemic diseases: An evolutionary trade-off between acutely beneficial but chronically harmful programs. Ferri FF. The remainder had hypogammaglobulinemia or a normal-appearing pattern. This pattern represents the presence of polyclonal immunoglobulin. How is a serum sample collected for an immunofixation test? Protein electrophoresis alone is not considered an adequate screen for monoclonal gammopathies. Your doctor can use it to confirm certain diagnoses. In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process. The net charge (positive or negative) and the size and shape of the protein commonly are used in differentiating various serum proteins.1. 2019 Jan. [QxMD MEDLINE Link]. This abnormal protein is formed within your bone marrow, the soft, blood-producing tissue that fills in the center of most of your bones. Are you a BCIT News insider? Abnormalities in any of these tests should result in a referral to a hematologist-oncologist. 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. 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. How is an immunofixation test interpreted? An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. Save my name, email, and website in this browser for the next time I comment. Philadelphia: Wolters Kluwer Health, Lippincott Williams & Wilkins; c2014. 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. 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. 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. Guido Tricot. This monoclonal gammopathy occurs in younger patients. [3], Waldenstrom macroglobulinemia Urine protein electrophoresis (UPEP) is, C-reactive protein is produced by the liver in response to inflammation. It can also can vary in how that amount relates to the behavior of the myeloma. [Full Text]. Our mission is to provide practice-focused clinical and drug information that is reflective of current and emerging principles of care that will help to inform oncology decisions. Therefore, such an approach cannot be currently recommended. Other more-specific tests, including serum protein electrophoresis (SPEP), can help determine the exact source, such as liver or bone marrow. Given the dismal impact on prognosis in the latter scenario, Red top tube for the collection of serum used. If abnormal, the curve may be delineated in the wrong location(s) and should be fixed before the result is filed. The identification of a monoclonal gammopathy depends on serum and urine protein electrophoresis and immunoelectrophoresis (IFE) 1 and/or quantitative free light chain assays. When you arrive, a healthcare professional will simply use a needle to take a blood sample. We look forward to connecting with you. To use the sharing features on this page, please enable JavaScript. Monoclonal proteins can be either intact monoclonal immunoglobulins or immunoglobulin light chains (Bence Jones proteins) found in the blood and/or urine. 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). Beta1 is composed mostly of transferrin, and beta2 contains beta-lipoprotein. [10]. Yet, every person's myeloma is unique. 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. This is a normal serum protein electrophoresis (SPE) pattern; also listed are a few of the proteins associated with each fraction. CancerTherapyAdvisor.com is a free online resource that offers oncology healthcare professionals a comprehensive knowledge base of practical oncology information and clinical tools to assist in making the right decisions for their patients. San Francisco: Said Support; c2013-2016. A hair strand drug test can be used to detect drugs used over the past 90 days. In Kelowna I had the week of review, and go out 2-3 mornings a week while in Chem and Hematology.
