Serum protein electrophoresis (SPEP)

Serum protein electrophoresis (SPEP) is a laboratory technique that’s used to determine the levels of some types of proteins in a blood sample. There are a number of reasons why a doctor may order this test. SPEP is used to help diagnose and monitor a variety of different diseases or disorders that have abnormal proteins or protein levels. Electrophoresis is not usually used by itself to diagnose a disease. Instead, it’s used along with other laboratory tests to provide more information to help with diagnosis.
