Serum/plasma protein electrophoresis (qualitative)

What Does This Test Measure?

The test uses a technique called electrophoresis to separate proteins based on their size and electrical charge. Different protein bands appear on a gel, each representing a distinct protein type (e.g., albumin, globulins). A healthcare provider will analyze these bands to look for patterns or abnormalities.

Why Might You Need This Test?

You may need this test if you have symptoms like unexplained weight loss, fatigue, swelling, or if your doctor suspects conditions such as multiple myeloma, liver disease, kidney disease, or certain autoimmune disorders. It can also be used to monitor treatment progress.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is then separated into serum or plasma for testing. No special preparation is needed, but fasting may be advised depending on your specific situation.

Common Conditions Monitored

This test can help detect or track conditions like multiple myeloma (a cancer of plasma cells), Waldenström macroglobulinemia (a type of lymphoma), liver disease (e.g., cirrhosis), kidney disease, and certain autoimmune diseases. It may also be used to evaluate protein abnormalities in hereditary conditions.
