For patients with MGUS and high risk for progression to multiple myeloma, surveillance should be performed at 6 months and then yearly thereafter. 5 fractions are shown in this image: albumin, alpha-1 ( 1 ), alpha-2 ( 2 ), beta () and gamma (). Anemia, pancytopenia, hypercalcemia, and renal disease may be present. 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. 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. Some people may experience a rash or nerve problems, such as numbness or tingling. 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 can also detect changes in the ratio of kappa and lambda light chain production, which indicates an excess of abnormal plasma cells. Immune Thrombocytopenia Purpura (ITP): What helps? [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. If the curve is relatively normal (e.g. They have a number of roles: Too much or too little protein can cause problems. Serum protein electrophoresis is used to identify patients with multiple myeloma and other serum protein disorders. [13, 14], Diagnosis of plasma cell dyscrasias Learn more about laboratory tests, reference ranges, and understanding results. Here are my blood test results for "Interpretation" part. 109:585-8. 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. To confirm the former and because of the latter, if there is a high index of clinical suspicion, immunofixation studies are required. 2010. IgA or some other type). When the whole immunoglobulin is present in the urine, it is usually at a low level. Rochester (NY): University of Rochester Medical Center; c2019. Monoclonal gammopathies are conditions in which abnormal proteins are found in the blood. Collection in a container: A plastic collection container is used. Most patients with untreated myeloma have a monoclonal immunoglobulin spike in serum, urine, or both. Enter your information to receive occasional news and important updates!

Immunofixation is clearly indicated upon clinical or laboratory evidence of a plasma cell dyscrasia for the diagnosis of multiple myeloma, Waldenstrom macroglobulinemia, or amyloid light-chain (AL) amyloidosis. Although this spike is usually greater than 3 g per dL in patients with multiple myeloma, up to one fifth of patients with this tumor may have an M-protein spike of less than 1 g per dL.10 Hypogammaglobulinemia on serum protein electrophoresis occurs in about 10 percent of patients with multiple myeloma who do not have a serum M-protein spike.11 Most of these patients have a large amount of Bence Jones protein (monoclonal free kappa or lambda chain) in their urine.11 Thus, the size of the M-protein spike is not helpful in excluding multiple myeloma. 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.

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. Immunoglobulins are proteins that function as antibodies, which fight infection. Monoclonal gammopathy of undetermined significance (MGUS) (adult). Guido Tricot. The Licensed Content is the property of and copyrighted by DSM. 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. When these are removed, a liquid is left behind. The article also provides a simple guide to result interpretation and suggestions on follow-up of abnormal results. Bone marrow biopsy may be useful to show aggregates of plasma cells in focal or diffuse patterns. Protein electrophoresis serum : Overview; [updated 2021 Aug 9; cited 2021 Aug 9]; [about 2 screens]. You are being redirected to 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. Accessed April 18, 2019. Electrophoresis is a method of separating proteins based on their physical properties. In some patients, the myeloma cells do not make a complete monoclonal immunoglobulin molecule with two heavy and two light chains. 2015 Oct. 47 (6):564-9. The SFLC assay can detect abnormal levels of free light chains, which may be an indication of a plasma cell disorder. Bethesda (MD): U.S. Department of Health and Human Services; NCI Dictionary of Cancer Terms: multiple myeloma; [cited 2019 Dec 10]; [about 3 screens]. Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. Philadelphia, PA, USA: Elsevier Churchill Livingstone; 2008. chapter 87. On a computer screen, these proteins form a pattern of bands. [16]. It measures the amount of two kinds of protein in your body, albumin and globulin. Myeloma is a cancer of plasma cells, a type of white blood cell (WBC) in the bone marrow that is responsible for making immunoglobulins. Bird J, Behrens J, Westin J, et al. 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). Immunoglobulins are secreted by plasma cells, a type of white blood cell in the bone marrow, in response to infection and disease. You may feel a little sting when the needle goes in or out. URL of this page: https://medlineplus.gov/lab-tests/immunofixation-ife-blood-test/. Healthcare providers treat the underlying cause of the immune response to help treat polyclonal gammopathy. When might mass spectrometry be used in place of immunofixation? No monoclonal band is identified. These tests are done in conjunction with immunofixation for example, serum immunofixation electrophoresis (SIFE), which identifies immunoglobulins in blood samples. [Full Text]. One pathologic reason which we covered at BCIT is a monoclonal gammopathy. [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. bone pain.

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. We look forward to connecting with you. MGUS causes no symptoms. 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. 22:1262-8. Fluorescence in situ hybridization (FISH) is a type of laboratory test that uses special dyes to identify mutations of specific chromosomes in cells. The monoclonal band is seen in: Multiple myelomas show in 99 % of the patients in serum and urine. In fact, if no monoclonal component is detected by serum protein electrophoresis, immunofixation interpretation with bone marrow evaluation determines the type of response, stratifying. Any one or more of the following myeloma-defining events: Evidence of end-organ damage that can be attributed to the disease: (CRAB criteria), Clonal plasma cells in the bone marrow 60% with or without CRAB, Ratio of involved/uninvolved serum free light chain ratio 100 (involved free light chain levels must be 100mg/L), One or more focal lesions found on MRI studies (at least 5 mm in size), Bone/skeletal survey (x-rays of all the bones in the body), Whole body low-dose computed tomography (CT) scan, Positron emission tomography and computed tomography (PET-CT) scan, Download or order The Leukemia & Lymphoma Society's free booklets. 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. See additional information. The beta fraction has two peaks labeled beta1 and beta2. What is the clinical application of an immunofixation test? Myeloma Protein (M Protein): What Is It? | MyMyelomaTeam A concomitant measurement of the creatinine in the 24-hour urine sample for correction of sampling errors has been proposed. [10, 17], A 24-hour concentrated urine sample is appropriate for urine immunofixation. excess of an abnormal immunoglobulin called monoclonal protein (or M protein). The immunoelectrophoresis-serum test is used to. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. The presence of M proteins can be a sign of a type of cancer called myeloma, or multiple myeloma. Electrophoresis is a lab technique used to separate groups of proteins in blood serum. If abnormal, the curve may be delineated in the wrong location(s) and should be fixed before the result is filed. A decreased alpha1-protein band may occur because of alpha1-antitrypsin deficiency or decreased production of the globulin as a result of liver disease. The names of these subsets are based on the method that is used to separate and differentiate the various serum components. Monoclonal gammopathy of undetermined significance (MGUS) and smoldering (asymptomatic) multiple myeloma: IMWG consensus perspectives risk factors for progression and guidelines for monitoring and management.

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. 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. This content does not have an English version. Characterized by a sharp peak in the beta-gamma region, monoclonal gammopathies involve increased production of immunoglobulins, or antibodies (IgA, IgG, IgM, etc.). 147:22-42.

Sasson SC, McGill K, Wienholt L, Carr A, Brown DA, Kelleher AD, et al. 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. Note that the percent of plasma cells in the bone marrow, assessed by flow cytometry, is not the value used in the diagnostic criteria above. If all tests are normal, the pattern of follow-up in Figure 36 can be undertaken. 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 band pattern is specific for certain diseases. 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. 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. Malignant plasma cells in the bone marrow 10% or presence of bony or extramedullary plasmacytoma, confirmed by biopsy. 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).
