Immunofixation (IFE) Blood Test: MedlinePlus Lab Test Information

What is an immunofixation (IFE) blood test?

An immunofixation blood test, also regarded as protein electrophoresis, measures certain proteins in the blood. Proteins enjoy quite a few vital roles, like offering electricity for the physique, rebuilding muscle mass, and supporting the immune method.

There are two primary forms of proteins in the blood: albumin and globulin. The test separates these proteins into subgroups dependent on their sizing and electrical charge. The subgroups are:

  • Albumin
  • Alpha-1 globulin
  • Alpha-2 globulin
  • Beta globulin
  • Gamma globulin

Measuring the proteins in each and every subgroup can aid diagnose a wide variety of diseases.

Other names: serum protein electrophoresis, (SPEP), protein electrophoresis, SPE, immunofixation electrophoresis, IFE, serum immunofixation
