The names of these subsets are based on the method that is used to separate and differentiate the various serum components. What are considerations regarding immunofixation results in multiple myeloma, and what are the limitations of a 24-hour concentrated urine sample for immunofixation testing? ), 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. Abnormalities in any of these tests should result in a referral to a hematologist-oncologist. In addition, a beta2 microglobulin test, a CRP test, and a 24-hour urine collection for electrophoresis and immunofixation should be performed. The light chain is also called the Bence Jones protein, named for the doctor Henry Bence Jones who studied its characteristics. 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. Immunoelectrophoresis - urine - UCSF Health When screening a patient or establishing a first-time diagnosis for a monoclonal gammopathy, consider ordering DMOGA / Monoclonal Gammopathy, Diagnostic, Serum instead, which includes free light chain analysis. What Is M Protein? Monoclonal gammopathy of undetermined significance. Healthcare providers treat the underlying cause of the immune response to help treat polyclonal gammopathy. Myeloma Protein (M Protein): What Is It? | MyMyelomaTeam 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. Monoclonal antibodies could be used as myeloma treatments and can be identified by serum protein electrophoresis and immunofixation electrophoresis. The alpha1-protein fraction is comprised of alpha1-antitrypsin, thyroid-binding globulin, and transcortin. Monoclonal gammopathy of undetermined significance (MGUS). The procedure was nearly identical to one of our labs at BCIT, so Im glad to have had a bit of experience in preparing the gel and dispensing the antisera. Plasma protein levels display reasonably predictable changes in response to acute inflammation, malignancy, trauma, necrosis, infarction, burns, and chemical injury.

Please check with your financial advisor if you have more questions. What is the clinical application of an immunofixation test? Does My Patient with a Serum Monoclonal Spike have Multiple Myeloma? It's easier to check your kidney health at home now more than ever. The alpha2 component is increased as an acute-phase reactant. It may also depend on the unique patterns made by the proteins. Youve read {{metering-count}} of {{metering-total}} articles this month. 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. In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process, and they usually are associated with nonmalignant conditions. Shah D, Seiter K. Multiple myeloma. Urine immunoelectrophoresis is a lab test that measures immunoglobulins in a urine sample. . Skeletal lesions (e.g., lytic lesions, diffuse osteopenia, vertebral compression fractures) are present in 80 percent of patients. Head over to share your story and tell us about it. 2019 Jan.

How is a serum sample collected for an immunofixation test? This article provides a comprehensive review of serum protein electrophoresis, including a discussion of how the examination is performed, what it measures, and when it is indicated. [Full Text]. The proteins create separate bands on the gel, which are then analyzed by the laboratory. Finally, when several bands with sharp borders are seen after immunofixation in cerebrospinal fluid (CSF) but not in serum, the result is reported as positive for oligoclonal bands. Fortunately, the cause of an abnormal curve is not always pathologic. Bone Marrow Tests. 2011. Here are my blood test results for "Interpretation" part. https://www.uptodate.com/contents/search.

The albumin band represents the largest protein component of human serum. Myeloma is a cancer of plasma cells, a type of white blood cell (WBC) in the bone marrow that is responsible for making immunoglobulins. Protein Electrophoresis, Immunofixation Electrophoresis; [updated 2019 Oct 25; cited 2019 Dec 10]; [about 2 screens]. In the interpretation of serum protein electrophoresis, most attention focuses on the gamma region, which is composed predominantly of antibodies of the IgG type. 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. Myelomacells produce many copies of its anibody. That criteria is determined by a pathologist who reviews the bone marrow aspirate slides. The subsets of these proteins and their relative quantity are the primary focus of the interpretation of serum protein electrophoresis.1,3. Lab Tests Online [Internet].
