The method can be used to examine specific proteins in the blood, urine, and other body fluids. Skeletal lesions (e.g., lytic lesions, diffuse osteopenia, vertebral compression fractures) are present in 80 percent of patients. 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. MGUS is usually detected by chance when you have a blood test for another condition. An additional point to consider is the size of the M-protein spike. Suspected multiple myeloma, Waldenstrms macroglobulinemia, primary amyloidosis, or related disorder, Unexplained peripheral neuropathy (not attributed to longstanding diabetes mellitus, toxin exposure, chemotherapy, etc. Malignancy and acute inflammation (resulting from acute-phase reactants) can increase the alpha1-protein band. No monoclonal band is identified. Its a useful skill to maintain, as technologists especially those on off-shifts or at smaller sites may still collect through their career(s). Multiple Myeloma: Symptoms and Signs; 2016 Oct [cited 2019 Dec 10]; [about 3 screens]. However, the presence of oligoclonal bands does not necessarily confirm the diagnosis, as other conditions can present with oligoclonal bands in the CSF. Clinical course and management of monoclonal gammopathy of undetermined significance. M-protein level is usually greater than 3 g per dL. Plasma protein levels display reasonably predictable changes in response to acute inflammation, malignancy, trauma, necrosis, infarction, burns, and chemical injury. Mayo Clinic does not endorse companies or products. It can also detect changes in the ratio of kappa and lambda light chain production, which indicates an excess of abnormal plasma cells.

For patients with MGUS and high risk for progression to multiple myeloma, surveillance should be performed at 6 months and then yearly thereafter. 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. The band pattern is specific for certain diseases. Available from: UW Health [Internet]. This test is called serum protein electrophoresis (SPEP) test. Polyclonal gammopathy, also known as hypergammaglobulinemia, is a condition in which white blood cells make too many proteins (antibodies). Thus, it is most often present in the blood but not in the urine. Blood Cancer J. The "M" technically stands for "monoclonal," but M protein is often referred to as myeloma protein. LLS funds lifesaving blood cancer research around the world, provides free information and support services, and is the voice for all blood cancer patients seeking access to quality, affordable, coordinated care.

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. A serum thyroxine-binding globulin (TBG) level test is a blood test that measures the amount of TBG in your blood. Your results will show that your protein levels are in the normal range, too high, or too low. Among these, the committee stated that in the detection of monoclonal immunoglobulins, intact light-chain matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) mass spectrometry can be used in lieu of immunofixation in patient clinical assessments and in assessing clinical trial patients. Continuing Medical Education (CME/CE) Courses. M protein is made by abnormal plasma cells. The most common type of myeloma is IgG kappa, occurring in approximately 52 % of patients. Often, there are associated decreases in the albumin and transferrin levels.6 Table 26 lists characteristic patterns of acute-reaction proteins found on serum protein electrophoresis, along with associated conditions or disorders. This usually takes less than five minutes. The five groups of proteins usually considered during an SPEP test are: Electrophoresis is a lab technique used to separate groups of proteins in blood serum. Protein electrophoresis alone is not considered an adequate screen for monoclonal gammopathies. People with monoclonal gammopathy generally don't experience signs or symptoms. An apparent monoclonal protein on serum protein electrophoresis may or may not be a true monoclonal protein. To confirm the former and because of the latter, if there is a high index of clinical suspicion, immunofixation studies are required. Diagnosis of monoclonal gammopathy of undetermined significance. [QxMD MEDLINE Link]. [18, 19], Detection of a paraprotein by immunofixation is possible in lymphomas. Hematocrit is a blood test that is used to determine if you have low levels of hemoglobin in your blood (a condition called anemia). An endoscopy is used in a wide range of testing throughout the body. In many myeloma patients, the coordinated process of making and attaching light chains and heavy chains fails in the malignant plasma cells.

Benign monoclonal proteins were first described by Dr. Jan Waldenstrm in 1960 after he detected abnormal narrow hypergammaglobulinemia bands in serum protein electrophoresis (SPEP) samples from healthy individuals. Malnutrition, significant liver disease, renal loss (e.g., in nephrotic syndrome), hormone therapy, and pregnancy may account for a low albumin level. Cavuoti D, Baskin L, Jialal I. Peaks and valleys in the bands may mean that you may be making too many or too few of certain proteins. Myelomacells produce many copies of its anibody. 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. 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. There are several reasons a patients SPE curve could be abnormal. IgA or some other type). You are being redirected to Urine protein electrophoresis (UPEP) is, C-reactive protein is produced by the liver in response to inflammation. [14], Mass spectrometry is sometimes employed in place of immunofixation because of the latters limitations, such as in the detection of low-level disease. The alpha2 component is increased as an acute-phase reactant. What Is M Protein? There may be some slight bruising afterward. Your story might just end up on BCIT News. M protein is an abnormal protein caused by plasma cells. Less than 10% plasma cells are present in bone marrow, and patients have no lytic bony lesions, anemia, hypercalcemia, or renal insufficiency.

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. You don't need any special preparations for an immunofixation blood test. A monoclonal protein is produced by the abnormal, cancerous or precancerous cells. Synonym (s): paraprotein (2) . Urine Test. 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. In: Goldman-Cecil Medicine. This means that high or low levels of the five protein types examined during the test can point to different illnesses. There are five types of heavy chains, and each type is represented by a specific letter: IgG, IgA, IgD, IgE and IgM. When you arrive, a healthcare professional will simply use a needle to take a blood sample. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic Press.
