Quantitation of Serum Monoclonal Proteins - Oxford Academic When the whole immunoglobulin is present in the urine, it is usually at a low level. Enter your information to receive occasional news and important updates! Ramakrishnan N, Jialal I. Bence-Jones Protein. This allows them to be measured and analyzed individually. [7], The identification of oligoclonal bands in CSF is helpful in the diagnosis of multiple sclerosis. 2016 Jan 27 [cited 2019 Dec 18]; 2016 (1):37-51. SPEP is used to help diagnose and monitor a variety of different diseases or disorders that have abnormal proteins or protein levels. MGUS usually causes no problems. An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. 2023 Healthline Media LLC. 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. If there's no disease progression, MGUS doesn't require treatment. What is the clinical application of an immunofixation test? There are a number of reasons why a doctor may order this test. Malnutrition, significant liver disease, renal loss (e.g., in nephrotic syndrome), hormone therapy, and pregnancy may account for a low albumin level. Further investigation will usually be needed to make a definitive diagnosis. 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). These values may vary slightly from facility to facility. These measurements indicate the degree to which the myeloma cells in the marrow are affecting normal blood cell development. Clinical course and management of monoclonal gammopathy of undetermined significance. This means that high or low levels of the five protein types examined during the test can point to different illnesses. Serum protein bands (monoclonal gammopathy) will sometimes be found following serum protein electrophoresis in patients presenting with classic signs or symptoms of multiple myeloma, e.g. Does My Patient with a Serum Monoclonal Spike have Multiple Myeloma? Copyright 2017, 2013 Decision Support in Medicine, LLC. There are two types of light chains, referred to as kappa (k) and lambda ().. ), New-onset anemia associated with renal failure or insufficiency and bone pain, Back pain in which multiple myeloma is suspected, Hypercalcemia attributed to possible malignancy (e.g., associated weight loss, fatigue, bone pain, abnormal bleeding), Rouleaux formations noted on peripheral blood smear, Renal insufficiency with associated serum protein elevation, Unexplained pathologic fracture or lytic lesion identified on radiograph, Viral infections, especially hepatitis, human immunodeficiency virus infection, mononucleosis, and varicella, M protein appears as a narrow spike in the gamma, beta, or alpha. IFE classifies the monoclonal based on the type of heavy (IgG, IgA or IgM) and light (kappa or lambda) chains that make up the antibodies. Electrophoresis is not usually used by itself to diagnose a disease. Measuring M-Protein SPEP, UPEP Tests | Int'l Myeloma Fdn To use the sharing features on this page, please enable JavaScript. 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. The next five components (globulins) are labeled alpha1, alpha2, beta1, beta2, and gamma. High protein levels may be caused by many conditions. Monoclonal gammopathy of undetermined significance. [Full Text]. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Is there something going on we should know about? 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. The remainder had hypogammaglobulinemia or a normal-appearing pattern. In blood cancers such as myeloma, the 'M' in 'M protein' stands for monoclonal. 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. 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. Seiter K, Ponce D. Waldenstrom macroglobulinemia. Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. But sometimes it can progress to more-serious diseases, including some forms of blood cancer. Monoclonal gammopathy of undetermined significance (MGUS) care at Mayo Clinic. [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. Alexandria (VA): American Society of Clinical Oncology; 20052019. 2015 Oct. 47 (6):564-9. Platelets Small substances in your blood that help the blood to form a thickened mass (or blood clot) to help stop bleeding. Available from: National Cancer Institute [Internet]. Immunofixation electrophoretic techniques applied to identification of proteins in serum and cerebrospinal fluid. Bethesda (MD): U.S. Department of Health and Human Services; NCI Dictionary of Cancer Terms: leukemia; [cited 2019 Dec 10]; [about 3 screens]. Medscape Drugs & Diseases. Common causes of low levels include: Your diagnosis will depend on which specific protein levels were not normal, and whether the levels were too high or too low. A second screen is used to confirm positive test results. 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. Anastasios Dimou, MD Resident Physician, Department of Internal Medicine, Albert Einstein Medical CenterDisclosure: Nothing to disclose. Monoclonal gammopathy is present in up to 8 percent of healthy geriatric patients.12 All patients with monoclonal gammopathy require further evaluation to determine the cause of the abnormality.

Immunofixation (IFE) Blood Test: MedlinePlus Medical Test Efficacy and outcome of autologous transplantation in rare myelomas. The light chain is also called the Bence Jones protein, named for the doctor Henry Bence Jones who studied its characteristics. 135:1048-51. 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. An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. Accessed April 18, 2019. Washington D.C.: American Association for Clinical Chemistry; c20012019. Ceruloplasmin, alpha2-macroglobulin, and haptoglobin contribute to the alpha2-protein band. 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. Pathol Biol (Paris). This test measures the numbers of red blood cells, white blood cells and platelets in the blood. Affected patients have no M protein in their urine, no lytic bone lesions, no anemia, no hypercalcemia, and no renal disease. IgA or some other type). Peripheral blood smear often shows RBC aggregates in a rouleaux formation. The precise cause of MGUS isn't known. 24:1121-7. Copyright 2023 American Academy of Family Physicians. As denoted in the normal curve above, antibodies are primarily found in the fraction. Want to view more content from Cancer Therapy Advisor? Autoinflammatory vs. Autoimmune: What is the Difference? If a monoclonal protein is present, a precipitant will form at this phase. See additional information. Murray DL, Puig N, Kristinsson S, et al. The proteins are separated into 5 or 6 fractions and displayed as a curve and corresponding gel pattern. Affected patients have hyperviscosity and hypercellular bone marrow with extensive infiltration by lymphoplasma cells. Most patients with untreated myeloma have a monoclonal immunoglobulin spike in serum, urine, or both. 1998. An endoscopy is used in a wide range of testing throughout the body. 1 The term monoclonal gammopathy of undetermined significance (MGUS) was coined by Dr. Robert Kyle in 1978 to describe an asymptomatic plasma cell dyscrasia characterized by a . In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process. Cytogenetic Analysis. 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. Also, M proteins may not be apparent on electrophoresis. [QxMD MEDLINE Link]. Malnutrition; [updated 2019 Nov 11; cited 2019 Dec 10]; [about 2 screens]. A negative urine or serum immunofixation result does not always rule out a plasma cell dyscrasia, as a nonsecretory or oligosecretory multiple myeloma can present with a negative immunofixation finding in both the urine and the serum. 2019 May 23. To confirm the former and because of the latter, if there is a high index of clinical suspicion, immunofixation studies are required. Washington D.C.: American Association for Clinical Chemistry; c20012019. 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. 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. In Greek, the language of most medical terms, "myelo" refers to the blood-producing cells in the bone marrow, and "oma" refers to a tumor or mass of cancer cells. Monoclonal gammopathy of undetermined significance (MGUS) (adult). 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. CBC often reveals a normochromic normocytic anemia. In healthy individuals, antibodies produced by plasma cells in the bone marrow help this process. This causes the different types of proteins to move and group together. Figure 1 shows a typical normal pattern for the distribution of proteins as determined by serum protein electrophoresis. Diagnosis requires 10 to 15 percent plasma cell involvement on bone marrow biopsy. The search for meaning in monoclonal protein. Is it multiple - PubMed Yet, every person's myeloma is unique. 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. 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. [18, 19], Detection of a paraprotein by immunofixation is possible in lymphomas. How is a urine sample collected for an immunofixation test? Therefore, such an approach cannot be currently recommended. In the interpretation of serum protein electrophoresis, most attention focuses on the gamma region, which is composed predominantly of antibodies of the IgG type. 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). The M protein has an incomplete heavy chain and no light chain. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. Clin Chem. In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process, and they usually are associated with nonmalignant conditions. Under the PE Value it says: "SPE1". Diagnosis of monoclonal gammopathy of undetermined significance. The most common conditions in the differential diagnosis of polyclonal gammopathy are listed in Table 3.8,9, An M protein is characterized by the presence of a sharp, well-defined band with a single heavy chain and a similar band with a kappa or lambda light chain. Making sense of serum protein bands. 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. It's easier to check your kidney health at home now more than ever. what does no apparent monoclonal protein on serum electrophoresis mean. Malabsorption; [updated 2019 Nov 11; cited 2019 Dec 10]; [about 2 screens]. [Full Text]. The presence of oligoclonal bands in CSF but not in the serum, given their intrathecal production, is helpful in the diagnosis of multiple sclerosis. 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 Many subspecialists include serum protein electrophoresis screening in the initial evaluation for numerous clinical conditions. Polyclonal gammopathy, also known as hypergammaglobulinemia, is a condition in which white blood cells make too many proteins (antibodies). Interpreting serum protein electrophoresis (SPE) patterns If the monoclonal protein level decreases or is undetectable after chemotherapy, it might indicate a response to treatment. 2nd Ed, Kindle. There is very little risk to having a blood test. Healthline Media does not provide medical advice, diagnosis, or treatment. Cavuoti D, Baskin L, Jialal I. Instead, its used along with other laboratory tests to provide more information to help with diagnosis. The method can be used to examine specific proteins in the blood, urine, and other body fluids. Your doctor tests your bone marrow to look for malignant plasma cells. Blood Cancer J. This test is most often used to help diagnose or monitor a variety of different conditions. Fanning SR, Hussein MA. Learn more about laboratory tests, reference ranges, and understanding results. Urine Immunofixation: Symptoms, Treatment, and More - WebMD Profile Information: Reflex Test: It may also depend on the unique patterns made by the proteins. Immune Thrombocytopenia Purpura (ITP): What helps? Available from: UW Health [Internet]. Immunoglobulins, known as Igs, are a group of proteins that help protect your body from illness. These include: You may need testing if you have symptoms of certain diseases, such as multiple myeloma, multiple sclerosis, malnutrition, or malabsorption. 109:585-8. There is greater than 10 percent plasma cell involvement on bone marrow biopsy. You don't need any special preparations for an immunofixation blood test. 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 light chains also called or Bence Jones protein, are seen in the urine of Multiple myeloma cases in 75 % of the patients. Albumin, the major protein component of serum, is produced by the liver under normal physiologic conditions. Is there a person or breakthrough we should celebrate? Monoclonal bands are usually seen in the zone but may be seen in proximity of the band or, rarely, in the 2 region. Following my rotation in Anatomical Pathology, I spent one week on accessioning review and another three in Chemistry. 2019 Jun 20. The various proteins in the body perform different functions. 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. Medscape Drugs & Diseases. Beaumont-Epinette MP, Moreau C, Besnard S, Latute F, Collet N, Sebillot M, et al. Suspected multiple myeloma, Waldenstrms macroglobulinemia, primary amyloidosis, or related disorder, Unexplained peripheral neuropathy (not attributed to longstanding diabetes mellitus, toxin exposure, chemotherapy, etc.
