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.

An ANA test is a blood test that looks for antinuclear antibodies in your blood. Antibodies are proteins that your immune system makes to fight foreign substances, like viruses and bacteria. But an antinuclear antibody attacks your healthy cells instead. It's called "antinuclear" because it targets the nucleus of the cells, which is in charge of sending signals that are needed for important cell functions.
