How is Immunofixation performed?
The technique consists of depositing a serum (or urine which has been previously concentrated) sample on a gel. After application of an electric current that allows the separation of proteins according to their size, antibodies specific for each type of immunoglobulin are laid upon the gel.
What is a Immunofixation test for?
What is an immunofixation (IFE) blood test? An immunofixation blood test, also known as protein electrophoresis, measures certain proteins in the blood. Proteins play many important roles, including providing energy for the body, rebuilding muscles, and supporting the immune system.
How is M spike calculated?
And for those readers who are interested in the specific formulas, here we go : First calculate your Gamma Gap (GG) : the number for Total Serum Protein less the number for Albumin. Early in the treatment program : M-Spike = =-2.50+0.95GG. Midpoint of therapy : M-spike=-2.33+0.88GG.
Why would a doctor order an Immunofixation test?
This blood test finds out if your body is making or losing protein in abnormal amounts.. It can also tell if you are having problems absorbing protein from foods. This test helps diagnose or check on conditions linked to health problems like the blood cancer multiple myeloma.
What is immunofixation vs electrophoresis?
Urine protein electrophoresis (UPEP) is used to identify the presence of the Bence Jones protein in urine. Immunofixation is used to identify the subtype of protein (ie, IgA lambda).
Does immunofixation detect light chains?
After recognition of a localized band suggestive of an M protein on SPEP, immunofixation is necessary for confirmation and to determine the heavy- and light-chain class of the M protein.
What is the difference between Immunofixation and electrophoresis?
What is the difference between Spep and Immunofixation?
In addition, immunofixation technique can also determine the particular isotype of the monoclonal protein. However, immunofixation technique cannot estimate the quantity of the M protein. In contrast, SPEP is capable of estimating the concentration of an M protein.
What is a high level of paraprotein?
paraprotein in your blood that is more than 30 g/L. level of abnormal plasma cells in your bone marrow that is between 10% and 60% no features of CRAB (including bone lesions on scans that are not causing symptoms)
Can you have myeloma without M spike?
Nonsecretory multiple myeloma (NSMM) is a rare variant of the classic form of MM that has a similar clinical and radiologic presentation except for the absence of the M-protein in serum and/or urine. Depending on the author, NSMM may have or not detectable monoclonal free light chain in urine/serum.
How long does it take to get Immunofixation results?
The Immunofixation (IFE) Serum Test detects and identifies monoclonal immunoglobulin gammopathies, which may indicate conditions such as multiple myeloma or Waldenstrom’s macroglobulinemia. Preparation: Fasting for 10-12 hours required. Test Results: 2-3 days. May take longer based on weather, holiday or lab delays.
