Serum/Plasma Substance Concentration by Immunoassay (General Protein Electrophoresis Profile)

What This Test Measures

Electrophoresis separates blood proteins based on size and charge, allowing for the identification of distinct protein bands. This test typically includes measurements for albumin, globulins (including immunoglobulins), and other proteins. The results help assess overall protein distribution and identify potential imbalances.

Common Conditions Evaluated

Protein electrophoresis is commonly used to detect conditions such as multiple myeloma (a cancer of plasma cells), liver disease (affecting albumin production), kidney disease (leading to proteinuria), and certain autoimmune disorders. It may also be used to monitor treatment responses.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in the arm. The blood is then separated into serum or plasma for analysis. This test does not require fasting and is typically performed on fresh or refrigerated samples.

Interpreting Your Results

Results are presented as a graphical profile showing the relative amounts of different protein fractions. Abnormal patterns may indicate specific protein abnormalities, such as elevated or low levels of certain globulins or albumin. Your healthcare provider will interpret these results in the context of your medical history and symptoms.
