Protein Electrophoresis by Immunofixation Blood Test
An immunofixation (IFE) blood test measures the number and type of proteins in your blood. Proteins have many important functions, including giving your body energy, rebuilding muscles, and helping your immune system. There are different types of proteins, and each one has a different job for your body. This test checks to see if your body is making or losing too much of certain proteins. Your body might make too much or too little protein if you have certain health conditions.
