The lab analyst performs immunoelectrophoresis, IEP, to evaluate a patient’s serum for the amounts and types of certain proteins, called immunoglobulins. The body produces immunoglobulins, also called antibodies, that activate as part of the immune response to neutralize specific invaders such as bacteria or viruses.
