Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. Alexandria (VA): American Society of Clinical Oncology; 20052019. excess of an abnormal immunoglobulin called monoclonal protein (or M protein). High amounts of M protein in a person's blood or urine may be a sign they have multiple myeloma but the presence of M proteins could also indicate other types of plasma cell tumors. 117:4701-5. This allows them to be measured and analyzed individually. Does My Patient with a Serum Monoclonal Spike have Multiple Myeloma? Sample: Serum (whole blood or plasma is inappropriate, as fibrinogen may alter the results), Sample: 24-hour urine collection, concentrated. Immunofixation: Reference Range, Interpretation, Collection and Panels In healthy individuals, antibodies produced by plasma cells in the bone marrow help this process. People with monoclonal gammopathy generally don't experience signs or symptoms. A polyclonal immunoglobulin pattern in the serum or urine immunofixation is considered to be nonspecific. 2019 Jan. [QxMD MEDLINE Link]. What is the clinical application of an immunofixation test? There are two main types of proteins in the blood: albumin and globulin. My first week back in Chem was spent on the electrophoresis bench. 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. 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. Exp Ther Med. This whole (intact) immunoglobulin, made of the four chains, is usually too large to pass through the kidney. The remainder had hypogammaglobulinemia or a normal-appearing pattern. The monoclonal band is seen in: Multiple myelomas show in 99 % of the patients in serum and urine. This content does not have an English version. Rochester (NY): University of Rochester Medical Center; c2019. Madison (WI):University of Wisconsin Hospitals and Clinics Authority; c2021. There are several reasons a patients SPE curve could be abnormal. 2019 Jun 20. Blood Chemistry Tests. Mayo Clinic does not endorse companies or products. Protein electrophoresis serum : Overview; [updated 2021 Aug 9; cited 2021 Aug 9]; [about 2 screens]. Goldman L, et al., eds. Bone Marrow Tests. ), 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. Here are my blood test results for "Interpretation" part. Washington D.C.: American Association for Clinical Chemistry; c20012019. A C-reactive protein test, or CRP test, measures the amount of CRP in your. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. [12] an additional assay for the identification of IgD or IgE must be performed. Affected patients have no M protein in their urine, no lytic bone lesions, no anemia, no hypercalcemia, and no renal disease. Affected patients have few bone lesions and few hematologic disturbances. Given the dismal impact on prognosis in the latter scenario, Copyright 2017, 2013 Decision Support in Medicine, LLC. The presence of M proteins can be a sign of a type of cancer called myeloma, or multiple myeloma. Close more info about Monoclonal Protein on Serum Protein Electrophoresis (M Component), Metabolic Alkalosis: Arterial Blood pH Elevated with Increased Arterial pCO2. An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. If Waldenstrms macroglobulinemia or other lymphoproliferative process is suspected, an abdominal computed tomographic scan and bone marrow aspiration and biopsy should be performed. 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). Figure 1 shows a typical normal pattern for the distribution of proteins as determined by serum protein electrophoresis. [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. If abnormal, the curve may be delineated in the wrong location(s) and should be fixed before the result is filed. It measures the amount of two kinds of protein in your body, albumin and globulin. Are you a BCIT News insider? This usually takes less than five minutes. Definitive diagnosis of multiple myeloma requires 10 to 15 percent plasma cell involvement as determined by bone marrow biopsy. 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. To use the sharing features on this page, please enable JavaScript. The method can be used to examine specific proteins in the blood, urine, and other body fluids. Murray DL, Puig N, Kristinsson S, et al. 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 Posts: 33. Your doctor can use it to confirm certain diagnoses. In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process. IgA, IgM, and sometimes IgG, along with complement proteins, also can be identified in the beta fraction. correct number of peaks and protein values), the analyzer does a pretty good job of identifying each fraction. Alexandria (VA): American Society of Clinical Oncology; 20052019. 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 . If the curve is relatively normal (e.g. All material on this website is protected by copyright, Copyright 1994-2023 by WebMD LLC. The immunoelectrophoresis-serum test is used to. 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. M protein is made by abnormal plasma cells. 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. There are five types of heavy chains, and each type is represented by a specific letter: IgG, IgA, IgD, IgE and IgM. 2018 Sep 7. The net charge (positive or negative) and the size and shape of the protein commonly are used in differentiating various serum proteins.1. 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. However, the presence of oligoclonal bands does not necessarily confirm the diagnosis, as other conditions can present with oligoclonal bands in the CSF. Myeloma Protein (M Protein): What Is It? | MyMyelomaTeam 109:585-8. The stained gel is then sent to a pathologist for diagnosis. Typically present in low amounts, conditions such as multiple myeloma and Waldenstrms macroglobulinemia show proliferation of abnormal or cancerous plasma cells. Available from: National Cancer Institute [Internet]. The serum immunofixation test is most often done with a blood sample. Leukemia. 2010. Monoclonal gammopathies are conditions in which abnormal proteins are found in the blood. 2019 May 23. A decreased alpha1-protein band may occur because of alpha1-antitrypsin deficiency or decreased production of the globulin as a result of liver disease. These tests are done in conjunction with immunofixation for example, serum immunofixation electrophoresis (SIFE), which identifies immunoglobulins in blood samples. Each plasma cell produces one of five types of antibodies: IgG, IgA, IgM, IgE or IgD, and either kappa or lambda. Again, the lanes are broad and the transition to the lane borders is smooth. Making sense of serum protein bands. [Full Text]. Abnormal levels of certain chemicals may indicate that an organ is not working properly or they may be caused by cancer or other health conditions. Urine immunofixation uses electricity to push proteins from your urine sample through a kind of gel. A second screen is used to confirm positive test results. Bone marrow biopsy may be useful to show aggregates of plasma cells in focal or diffuse patterns. Join the BCIT conversation on social media.
