Immunofixation electrophoresis IFE is a two-stage procedure using agarose gel high-resolution electrophoresis in the first stage and immunoprecipitation in the second. Has application to the evaluation of lymphoproliferative disease malignant lymphoma and others and collagen disease in general.

Protein electrophoresis vs immunofixation. If screening for plasma cell dyscrasias the International Myeloma Working Group recommends a screening panel consisting of serum free light chain assay serum protein electrophoresis SPEP and serum immunofixation IFE to maximize sensitivity. Immunofixation electrophoresis IFE has largely replaced immunoelectrophoresis IEP see below for establishing the presence and isotype of a monoclonal immunoglobulin M-protein 8 9 Fig. Protein electrophoresis is used for the detection evaluation and follow-up of monoclonal gammopathy MG conditions such as Waldenstrm macroglobulinemia WM.
Plasma protein levels display reasonably predictable. For the detection of monoclonal gammopathies in the clinical laboratory and to identify the type as well as the heavy- and light-chain class. Results of Immunofixation Electrophoresis and Free Light Chain Ratios IFE Status Number of Patients Normal κλ Ratio Percent Normal Ratio.
Immunofixation electrophoresis IFE is currently the most common method for isotyping of monoclonal gammopathy because of its superior sensitivity relative to immunoelectrophoresis IEP. Immunofixation identified the proteins unambiguously in all six sera examined whereas immunoelectrophoresis gave ambiguous results in one of the sera with high protein concentration and in three of the sera with low protein concentration.

15012015 Serum and urine protein electrophoresis SPEP UPEP and immunofixation electrophoresis SIFE IUFE are commonly used in clinical laboratories for the detection and identification of M-proteins. A 24-hour urine IFE can be added if AL amyloidosis is suspected 2. The IFE test is used to identify monoclonal immunoglobulin gammopathies.
When a monoclonal band is found on serum protein electrophoresis which is done by a capillary tube method in this laboratory further tests are initiated to type the immunoglobulin class and light chain. This is done by serum immunofixation or immunotyping. It may also indicate conditions such as multiple myeloma or Waldenstroms macroglobulinemia.
Globulins Serum IEP Serum IFE Serum and Protein. Diagnose myeloma macroglobulinemia of Waldenstrm. 15122020 Immunofixation electrophoresis IFE is in all probability the gold standard.
An Immunofixation Electrophoresis Test then helps identify a specific protein in this fraction which is of clinical interest to the healthcare provider. The superiority of immunofixation resulted from its greater resolution. 09052018 A Protein Electrophoresis Test determines the fraction of different proteins present in blood or urine.
Proteins are first separated by electrophoresis. 30092020 Immunofixation electrophoresis is usually ordered when the protein electrophoresis test shows the presence of an abnormal protein band that may be an immunoglobulin. Immunofixation IFE Serum and Protein Electrophoresis Blood Test.
24102019 Protein electrophoresis and immunofixation electrophoresis detect and measure abnormal proteins or the absence of normal proteins in blood urine or CSF. An immunofixation blood test also known as protein electrophoresis measures certain proteins in the blood. Different patterns between SIFE and UIFE happen occasionally and laboratorians should understand the mechanisms behind the differences and additional tests.
Proteins play many important roles including providing energy for the body rebuilding muscles and supporting the immune system. IFE is easier to perform is somewhat more sensitive and is easier to interpret than IEP. Electrophoresis tests are most frequently requested when a doctor suspects a disease or condition that causes a monoclonal protein to be produced.
Immunofixation is used to evaluate monoclonal gammopathy M protein found on serum protein electrophoresis. This information provides clues that a disease is affecting protein production or loss of protein. 15052020 Electrophoresis separates proteins based on their physical properties and the subsets of these proteins are used in interpreting the results.
07082015 The initial test to detect and identify the paraprotein is serum protein electrophoresis. It has also replaced the classical immunoelectrophoresis because of its simplicity of interpretation.
