Serum or Plasma Electrophoresis (Qualitative) for Protein Electrophoresis

What Is Protein Electrophoresis Used For?

Protein electrophoresis is primarily used to diagnose and monitor conditions affecting protein levels in the blood. It can reveal abnormal protein bands that might suggest conditions such as multiple myeloma (a cancer of plasma cells), Waldenström macroglobulinemia, or other disorders like liver disease or kidney problems. This test is also part of screening for hereditary disorders or evaluating certain autoimmune diseases.

How Is This Test Performed?

A small blood sample is drawn from your arm, typically using a needle. The blood is then processed to separate serum or plasma, which is placed on a gel. An electric current is applied to the gel, causing proteins to move toward the opposite charge. Afterward, the gel is stained to visualize the different protein bands. The results are interpreted by a healthcare provider to identify any unusual patterns.

Preparation for the Test

No special preparation is usually needed for this test. However, you may be asked to avoid certain medications or supplements that could interfere with results, such as some blood thinners or certain vitamins. Always follow your healthcare provider’s instructions.

What Are the Possible Results?

The test produces a visual pattern of protein bands on the gel. Normal results show distinct bands representing different protein types. Abnormal results may show extra bands, missing bands, or unusual patterns that require further medical evaluation. Your healthcare provider will discuss these findings with you and may recommend additional tests if needed.
