An immunofixation (IFE) blood test is used to identify which of the following types of proteins in blood? [Select All That Apply]
a. Albumin
b. Alpha-1 globulin
c. Alpha-2 globulin
d. Beta globulin
e. Gamma globulin

Answer: (a,b, c, d, e)
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.
There are two main types of proteins in the blood: albumin and globulin. The test separates these proteins into subgroups based on their size and electrical charge. The subgroups are:

  1. Albumin
  2. Alpha-1 globulin
  3. Alpha-2 globulin
  4. Beta globulin
  5. Gamma globulin
Measuring the proteins in each subgroup can help diagnose a variety of diseases.
