The region is sometimes divided into 1 and 2, which would account for a sixth fraction. 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. Alexandria (VA): American Society of Clinical Oncology; 20052019. Common causes of high levels include: Low protein levels may be caused by many conditions. 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. Serum protein electrophoresis is used to identify patients with multiple myeloma and other serum protein disorders. University of Rochester Medical Center [Internet]. UK Myeloma Forum (UKMF) and Nordic Myeloma Study Group (NMSG): guidelines for the investigation of newly detected M-proteins and the management of monoclonal gammopathy of undetermined significance (MGUS). Complete Blood Count (CBC). Monoclonal Protein Study, Serum - mayocliniclabs.com This can help the doctor decide how well therapies and medicines are working. The presence of M proteins can be a sign of a type of cancer called myeloma, or multiple myeloma. To confirm the former and because of the latter, if there is a high index of clinical suspicion, immunofixation studies are required. 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. Philadelphia, Pa.: Elsevier; 2019. https://www.clinicalkey.com. Bone marrow biopsy may be useful to show aggregates of plasma cells in focal or diffuse patterns. Immunofixation in CSF for the detection of oligoclonal bands is indicated every time there is suspicion for multiple sclerosis. This sample is often difficult to collect, and suboptimal collection might alter the result. Eric B Staros, MD is a member of the following medical societies: American Medical Association, American Society for Clinical Pathology, Association for Molecular Pathology, College of American PathologistsDisclosure: Nothing to disclose. Protein Electrophoresis questions. Tests are done to measure the levels of many different substances in the blood. An apparent monoclonal protein on serum protein electrophoresis may or may not be a true monoclonal protein. You don't need any special preparations for an immunofixation blood test. In: Goldman-Cecil Medicine. Want to view more content from Cancer Therapy Advisor? It involves exposing serum placed in a. 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. Sample: Serum (whole blood or plasma is inappropriate, as fibrinogen may alter the results), Sample: 24-hour urine collection, concentrated. There are several reasons a patients SPE curve could be abnormal. What specimens can be used to perform an immunofixation test? The IFX test can also be used to study changes in the structure of normal. Immunoelectrophoresis - urine - UCSF Health Definitive diagnosis of multiple myeloma requires 10 to 15 percent plasma cell involvement as determined by bone marrow biopsy. A serum free light chain ratio is indicated in the case of a negative immunofixation result when the suspicion for multiple myeloma is still high. Rajhumar SV. excess of an abnormal immunoglobulin called monoclonal protein (or M protein). We want you to take advantage of everything Cancer Therapy Advisor has to offer. 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). https://www.uptodate.com/contents/search.

Diagnostic Approach to Patients with an IgM Monoclonal Protein Healthcare providers treat the underlying cause of the immune response to help treat polyclonal gammopathy. Join the BCIT conversation on social media. Kaplan JS, Horowitz GL. The most common condition linked with these abnormal proteins is MGUS. Albumin, the major protein component of serum, is produced by the liver under normal physiologic conditions. 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. MGUS usually causes no problems. If present, an excessive production of a monoclonal immunoglobulin may be shown in laboratory test results as a spike on a graph (M spike). We've rounded up the best at-home kidney health test kits. Portland (ME): Maine Health; c2019. Available from: Cancer.Net [Internet]. Each plasma cell produces one of five types of antibodies: IgG, IgA, IgM, IgE or IgD, and either kappa or lambda. 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. Accessed April 18, 2019. Once the serum samples are run on the analyzer, a technologist compares the curves with patients previous results and ensures the fractions are appropriately delineated. Healthline Media does not provide medical advice, diagnosis, or treatment. There are two types of light chains, referred to as kappa (k) and lambda ().. As denoted in the normal curve above, antibodies are primarily found in the fraction. Definition. This is serum. 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. Accessed April 18, 2019. Philadelphia: Wolters Kluwer Health, Lippincott Williams & Wilkins; c2014. These values may vary slightly from facility to facility. Malabsorption; [updated 2019 Nov 11; cited 2019 Dec 10]; [about 2 screens]. Immunofixation: Reference Range, Interpretation, Collection and Panels Your doctor can use it to confirm certain diagnoses. 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. Some people may experience a rash or nerve problems, such as numbness or tingling. 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. https://www.uptodate.com/contents/search.

Goldman L, et al., eds. Rochester (NY): University of Rochester Medical Center; c2019. Advertising revenue supports our not-for-profit mission. Serum protein electrophoresis is an inexpensive, easy-to-perform screening procedure for initial identification of monoclonal bands. Detection of oligoclonal bands in cerebrospinal fluid by immunofixation electrophoresis. If the monoclonal protein level decreases or is undetectable after chemotherapy, it might indicate a response to treatment. Other inflammatory conditions of the CNS can present with oligoclonal bands in CSF resulting from intrathecal production of antibodies. There are a number of reasons why a doctor may order this test. Electrophoresis separates proteins based on their physical properties, and the subsets of these proteins are used in interpreting the results. 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. Monoclonal bands are usually seen in the zone but may be seen in proximity of the band or, rarely, in the 2 region. Genetic changes and environmental triggers appear to play a role. 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.

Urbancek S, Gascon P, Schwartz RA, Jacobson DR, Buxbaum JN, Bogdan CA. 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. The identification of a monoclonal immunoglobulin is helpful in the diagnosis of the following conditions Cytogenetic Analysis. Available from: UF Health: University of Florida Health [Internet]. 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.
