What This Test Measures

Electrophoresis separates blood proteins based on size and charge. In this test, we analyze specific glycoproteins (proteins with sugar molecules attached) to detect any unusual distribution or presence of abnormal proteins.

Why It’s Done

Doctors may order this test if you have symptoms like unexplained weight loss, frequent infections, or fatigue, or if they suspect blood cancers like multiple myeloma or lymphoma. It can also help monitor treatment progress.

Sample Collection

A blood sample is drawn from a vein in your arm. The blood is processed to separate serum or plasma, which is then analyzed in a lab to identify protein patterns.

Preparation

No special preparation is needed, but avoid strenuous activity or eating heavy meals 24 hours before your test.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results?
Results are typically available within 1–3 business days, depending on lab processing times.
What does an abnormal result mean?
An abnormal result may signal an underlying blood disorder, but doctors will review your full medical history and other test results before diagnosing. Follow-up testing may be needed.
Can I eat or drink before this test?
Yes, you can eat and drink normally, but avoid heavy meals or exercise 24 hours before your blood draw.
